Defending the Faith 10
Opening Prayer
In the name of the Father, and of the Son, and of the Holy Spirit.
Amen.
Lord Jesus Christ,
You are the Way, the Truth, and the Life.
You call us not only to believe in You,
but to follow You.
Form our consciences, purify our hearts,
and teach us to love what is good, true, and holy.
Give us courage to receive Your teaching,
especially when it challenges us.
Amen.
In this series, we have been asking some of the questions Catholics are often asked.
Why be Catholic?
Did Jesus really found the Church?
Is the Bible enough?
Who has authority in the Church?
Why do Catholics go to Mass every Sunday?
Is the Eucharist really Jesus?
Why confess sins to a priest?
Why baptise babies?
Why do Catholics honour Mary and the saints?
In this session, we come to another very important question:
Why does the Church teach difficult moral truths?
Many people ask this.
They say:
“Why does the Church have so many rules?”
Or:
“Why does the Church talk about sin?”
Or:
“Why does the Church teach about marriage, sexuality, family, life, death, justice, money, and the body?”
Or:
“Shouldn’t people just follow their conscience?”
Or:
“Isn’t love what matters?”
Or:
“Why can’t the Church simply change with the times?”
These are serious questions.
They deserve a calm answer.
Because many people experience Catholic morality as a list of prohibitions.
Do not do this.
Do not do that.
That is not the heart of Catholic moral teaching.
The heart of Catholic morality is not control.
It is not negativity.
It is not hatred of the body.
It is not suspicion of happiness.
It is not God trying to catch us out.
The heart of Catholic morality is this:
God made us for love, truth, holiness, and eternal life.
The commandments are not prison bars.
They are the path of freedom.
The Church teaches difficult moral truths because Christ wants to save the whole person: body, soul, mind, heart, desires, relationships, choices, and eternal destiny.
Jesus does not only forgive us.
He changes us.
He does not only say:
“Your sins are forgiven.”
He also says:
“Go, and sin no more.”
That is mercy and conversion together.
1. Morality begins with God, not with rules
Catholic moral teaching does not begin with rules.
It begins with God.
God is good.
God is truth.
God is love.
God created us in His image.
That means human life has meaning.
The body has meaning.
Love has meaning.
Marriage has meaning.
Sexuality has meaning.
Freedom has meaning.
Suffering has meaning.
Death has meaning.
We are not random creatures inventing ourselves from nothing.
We are created by God and for God.
So morality is not something imposed from outside, as though God looked at human life and invented arbitrary tests.
Morality is built into reality.
It is about living according to the truth of what we are.
A fish is free in water, not on dry land.
A bird is free in the air, not buried underground.
A human being is free not by doing anything at all, but by living according to truth, love, and God’s design.
So when the Church teaches morality, she is not saying:
“Here are random rules.”
She is saying:
“This is the path of human flourishing.”
“This is what helps love become real.”
“This is what protects the weak.”
“This is what keeps us from slavery.”
“This is what leads to holiness.”
The commandments are not against happiness.
They are against the false happiness that destroys us.
2. Jesus calls us to conversion
Some people imagine Jesus as someone who only comforted and never challenged.
But that is not the Jesus of the Gospel.
Jesus is merciful.
He welcomes sinners.
He eats with tax collectors.
He forgives the fallen.
He touches the unclean.
He seeks the lost.
But He also calls people to repentance.
He says:
“Repent, for the kingdom of heaven is at hand.”
He says:
“If you love me, you will keep my commandments.”
He says:
“Enter by the narrow gate.”
He says:
“Whoever would come after me, let him deny himself and take up his cross and follow me.”
Jesus does not save us by leaving us unchanged.
He saves us by drawing us out of sin and into new life.
That means discipleship will sometimes be difficult.
Christ will challenge our pride.
He will challenge our anger.
He will challenge our greed.
He will challenge our lust.
He will challenge our dishonesty.
He will challenge our selfishness.
He will challenge our bitterness.
He will challenge the parts of us we most want to protect.
This is not because He hates us.
It is because He loves us too much to leave us enslaved.
A doctor who refuses to name the illness is not loving.
A parent who refuses to warn a child about danger is not loving.
A shepherd who refuses to call the sheep back from a cliff is not loving.
So when the Church teaches moral truth, she is not trying to condemn the world.
She is continuing the work of Christ, who calls sinners not only to forgiveness, but to conversion.
3. Freedom is not doing whatever I want
A great confusion today is the meaning of freedom.
Many people think freedom means:
“I can do whatever I want.”
Or:
“No one can tell me what to do.”
Or:
“My body, my choice.”
Or:
“My truth.”
But that is not real freedom.
If a person is ruled by anger, is that freedom?
If a person cannot resist lust, is that freedom?
If a person is enslaved to drink, drugs, pornography, gambling, money, approval, or resentment, is that freedom?
If a person always does whatever desire demands, is that freedom?
No.
That is slavery wearing the mask of freedom.
Real freedom is the power to choose the good.
It is the ability to love.
It is self-mastery.
It is the capacity to say yes to God and no to sin.
A person who cannot say no is not free.
A person who is controlled by appetite is not free.
A person who is trapped by selfishness is not free.
Christ comes to make us free.
But that freedom requires truth.
Jesus says:
“The truth will set you free.”
He does not say:
“Your preferences will set you free.”
He does not say:
“Your feelings will set you free.”
He says:
“The truth will set you free.”
This is why the Church teaches difficult truths.
Because falsehood enslaves.
Truth liberates.
At first, truth may feel restrictive.
But in the end, truth makes love possible.
4. Conscience must be formed
People often say:
“I just follow my conscience.”
That can sound good.
And conscience does matter deeply.
No one should act against conscience.
But conscience is not simply a feeling.
It is not the same as personal preference.
It is not a private permission slip.
Conscience is the judgement by which we recognise what is right and wrong.
But conscience can be mistaken.
A person can sincerely believe something and still be wrong.
History is full of people who sincerely justified terrible things.
We can justify selfishness.
We can excuse cruelty.
We can normalise impurity.
We can explain away greed.
We can call cowardice prudence.
We can call revenge justice.
We can call convenience compassion.
That is why conscience must be formed.
A Catholic forms conscience by listening to Christ.
By reading Scripture.
By receiving the teaching of the Church.
By praying.
By examining one’s life honestly.
By going to Confession.
By seeking wise counsel.
By being willing to change.
The Church does not replace conscience.
She helps form conscience in truth.
A mature Catholic does not say:
“I will ignore my conscience.”
Nor does a mature Catholic say:
“My conscience means I can ignore the Church.”
A mature Catholic says:
“Lord, form my conscience so that I may recognise and choose the good.”
That is humility.
And without humility, conscience easily becomes self-approval.
5. Love is not the same as approval
Another common phrase is:
“Surely love is what matters.”
Yes.
Love matters absolutely.
Jesus says the greatest commandments are to love God and love our neighbour.
Saint Paul says that without love we are nothing.
But we must understand love properly.
Love is not the same as approval.
Love is not the same as agreeing with every choice.
Love is not the same as avoiding all difficult truths.
Love is willing the good of the other.
And the highest good of the other is salvation.
If someone is walking towards danger, love warns.
If someone is harming himself, love speaks.
If someone is trapped in sin, love does not say, “It does not matter.”
Love says:
“You were made for more than this.”
This is very important.
The Church’s moral teaching should never be expressed with cruelty.
It should never be used to humiliate.
It should never be spoken with contempt.
It should never be detached from mercy.
But mercy does not mean pretending sin is harmless.
Jesus loves sinners.
That is why He calls sinners to repentance.
A Church that stopped teaching moral truth would not be more loving.
She would be less loving.
She would be like a doctor who hides the diagnosis.
Or a lighthouse that switches off its light because ships do not like being warned about rocks.
True love tells the truth.
And true truth is spoken with love.
6. The body matters
Catholic morality often speaks about the body.
Marriage.
Sexuality.
Life in the womb.
Care for the sick.
Respect for the dying.
Modesty.
Purity.
Food.
Fasting.
Work.
Rest.
Why?
Because the body matters.
Christianity is not anti-body.
God created the body.
The Son of God took a human body.
Jesus healed bodies.
Jesus died in His body.
Jesus rose in His body.
Our bodies are temples of the Holy Spirit.
Our bodies will rise again.
So what we do with the body matters.
The body is not a meaningless object.
It is not raw material for the will.
It is not a costume for the self.
It is part of the person.
This is why Catholic teaching about sexuality is not a hatred of sex.
It is a defence of the meaning of the body, the dignity of the person, and the truth of love.
This is why the Church defends unborn children, the elderly, the sick, and the dying.
Because every human body belongs to a person made in the image of God.
This is why the Church teaches that marriage has a meaning given by God.
Because the body speaks a language.
The union of husband and wife is ordered towards faithful love and the gift of life.
The Church does not teach about the body because she is obsessed with rules.
She teaches because the body is sacred.
What we do with the body either tells the truth about love or tells a lie.
And Christ wants the whole person to be saved.
Not just thoughts.
Not just feelings.
The whole person.
Body and soul.
7. Difficult teaching is not hatred
This needs to be said clearly.
When the Church says that something is sinful, she is not saying the person is hated.
A person is never reducible to a sin.
Every human being is made in the image of God.
Every human being is loved by God.
Every human being is called to holiness.
Every human being deserves dignity, patience, justice, and pastoral care.
The Church’s moral teaching should never be used as an excuse for mockery, rejection, or cruelty.
That is not Catholic.
At the same time, dignity does not mean every choice is good.
Love does not mean every desire should be acted upon.
Respect does not mean truth disappears.
We must hold two truths together:
Every person must be loved.
Every person is called to conversion.
That includes all of us.
The angry person.
The proud person.
The greedy person.
The unfaithful person.
The impure person.
The dishonest person.
The resentful person.
The selfish person.
The lukewarm person.
The Church does not call only some people to conversion.
She calls everyone.
So difficult moral teaching should never be used to place “those people” outside the reach of mercy.
We are all sinners.
We all need grace.
We all need the Cross.
We all need conversion.
The Church’s moral teaching is not a weapon for the self-righteous.
It is medicine for the wounded.
And we are all wounded.
8. The Church cannot simply change the truth
Some people say:
“Why does the Church not change with the times?”
We need to answer carefully.
The Church can change many things.
She can change disciplines.
She can change pastoral methods.
She can change language.
She can change customs.
She can change schedules, structures, and ways of explaining.
The Church must always seek to speak the Gospel clearly in each age.
But the Church cannot change truth.
She cannot make evil good.
She cannot make falsehood true.
She cannot abolish the commandments.
She cannot invent a new human nature.
She cannot redesign the sacraments according to fashion.
She cannot say that what Christ taught no longer matters.
The Church is not the owner of truth.
She is its servant.
This is why some teachings cannot simply be voted away or adjusted by public opinion.
Truth is not decided by majority.
Holiness is not decided by fashion.
The Gospel is not edited by each generation.
This can be hard.
But it is also merciful.
Because if the Church simply changed her teaching every time culture changed, she would no longer be a reliable guide.
She would become an echo.
And the world does not need the Church to echo its confusion.
The world needs the Church to witness to Christ.
Always with humility.
Always with repentance for her own failures.
Always with patience.
But also with courage.
9. Moral teaching is for everyone, not only “serious sinners”
Sometimes people think Catholic morality is mainly about certain controversial issues.
But Catholic moral teaching concerns the whole of life.
It concerns how we speak.
How we spend money.
How we treat workers.
How we care for the poor.
How we forgive enemies.
How we use technology.
How we treat our bodies.
How we honour marriage.
How we protect life.
How we tell the truth.
How we keep promises.
How we worship God.
How we rest.
How we handle anger.
How we resist envy.
How we treat strangers.
How we care for creation.
How we die.
How we live.
No one escapes the call to conversion.
A person may be outwardly respectable and still be far from God.
A person may keep certain rules and still be proud, cold, dishonest, greedy, or cruel.
Jesus often speaks strongly to religious people who think they are righteous.
So when we speak of moral truth, we should not immediately think of other people.
We should ask:
Where is Christ calling me to conversion?
Where have I excused myself?
Where have I made peace with sin?
Where do I need grace?
The Church’s moral teaching is not a spotlight to shine only on others.
It is also a mirror for my own soul.
10. Grace makes holiness possible
If Catholic morality were only a list of demands, it would crush us.
But the Christian life is not lived by willpower alone.
Grace comes first.
Christ gives grace.
The Holy Spirit strengthens us.
The sacraments heal and nourish us.
Confession restores us.
The Eucharist feeds us.
Prayer changes us.
The saints help us.
The Church supports us.
This is important because many people hear moral teaching and think:
“I cannot live that.”
Sometimes, alone, that is true.
But we are not asked to live holiness alone.
Christ gives what He commands.
He does not merely point to the mountain and say, “Climb.”
He gives strength.
He walks with us.
He forgives us when we fall.
He lifts us up.
He teaches us to begin again.
This does not mean holiness is easy.
It means holiness is possible.
The Church’s moral teaching is demanding because human dignity is great.
God does not call us to mediocrity.
He calls us to sainthood.
And every saint is proof that grace can do what human weakness cannot do alone.
So if a teaching feels difficult, the Catholic response is not despair.
It is:
“Lord, give me grace.”
“Lord, form my heart.”
“Lord, help me take the next step.”
“Lord, teach me to love what You command.”
Conversion is often gradual.
But gradual does not mean false.
A person may struggle.
A person may fall.
A person may need patience, confession, guidance, and time.
But the goal remains holiness.
Mercy meets us where we are.
It does not leave us where we are.
11. How to answer this simply
So if someone asks:
“Why does the Church have so many rules?”
You might say:
“The Church’s moral teaching is not about control. It is about helping us live according to truth, love, and the dignity God has given us.”
If someone says:
“Shouldn’t people just follow their conscience?”
You can say:
“Conscience matters deeply, but conscience must be formed by truth. The Church helps us form conscience according to Christ.”
If someone says:
“Isn’t love what matters?”
You can say:
“Yes, love matters. But love is not the same as approving every choice. True love wants the good of the other, and the highest good is salvation.”
If someone says:
“Why can’t the Church change?”
You can say:
“The Church can change disciplines and pastoral methods, but she cannot change the truth about God, the human person, sin, grace, and salvation.”
If someone says:
“The Church hates people who disagree with her teaching,”
You can say:
“No. Every person is loved by God and must be treated with dignity. But love does not mean pretending every choice is good. Christ calls every one of us to conversion.”
Simple answers are often best.
The aim is not to win an argument.
The aim is to show that Catholic morality is not hatred, control, or fear.
It is the truth about love.
12. What this asks of us
If the Church teaches moral truth in the name of Christ, then each of us must become teachable.
We must not only ask:
“What does the Church say?”
We must ask:
“Lord, how are You calling me to conversion?”
Do I form my conscience?
Do I listen when the Church challenges me?
Do I confuse freedom with doing whatever I want?
Do I confuse love with approval?
Do I treat my body as a temple of the Holy Spirit?
Do I use moral teaching to judge others while excusing myself?
Do I believe grace can change me?
Do I go to Confession when I fall?
Do I ask for help where I struggle?
Do I want holiness, or only comfort?
Catholic morality is not mainly about winning arguments in public.
It is about becoming saints.
The Church teaches difficult truths because Christ calls us to difficult love.
And difficult love is often the love that saves.
So we must receive moral teaching not as an insult, but as an invitation.
An invitation to freedom.
An invitation to truth.
An invitation to healing.
An invitation to become fully alive in Christ.
Conclusion
So why does the Church teach difficult moral truths?
Because Christ is Lord of the whole person.
Because truth matters.
Because freedom is not doing whatever we want.
Because conscience must be formed.
Because love is more than approval.
Because the body is sacred.
Because sin wounds us.
Because grace heals us.
Because holiness is possible.
Because the Church is not free to change what Christ has given.
Because mercy calls us to conversion.
The Church’s moral teaching is not God trying to catch us out.
It is God calling us home.
It is not hatred of humanity.
It is reverence for what humanity is called to become.
It is not a list of arbitrary rules.
It is the path of love, truth, freedom, and holiness.
So we do not say:
“I will follow Christ only where He agrees with me.”
We say:
“Lord, teach me, even when Your teaching challenges me.”
We do not say:
“My desires define the truth.”
We say:
“Lord, purify my desires according to Your truth.”
We do not say:
“The Church should simply echo the world.”
We say:
“Lord, make Your Church faithful, courageous, humble, and merciful.”
To summarise, remember these three simple answers.
Why does the Church teach difficult moral truths?
Because Christ calls the whole person to holiness.
Because truth and love belong together.
Because real freedom means being able to choose the good.
If you remember nothing else, remember this:
Catholic morality is not about God catching us out. It is about Christ setting us free to love truly and become holy.
Each of us should ask:
Where do I need Christ to convert my heart?
Because moral teaching is not only something to defend.
It is something to live.
Amen.
