About this session

Theme: The Old Law and the New: Learning Freedom

God does not give his law because he wants to make human life smaller. He gives his law because he made us for freedom, goodness, and happiness with him. This session looks at the Old Law, especially the Ten Commandments, and the New Law of Christ, especially the commandment of love and the Beatitudes.

The Church teaches this because Christian life is not only believing ideas about God; it is learning to live as his children. God first taught Israel how to live as a freed people after delivering them from slavery. In Christ, he goes even deeper: he frees us from sin and gives the Holy Spirit so that God’s law can be written in our hearts. This also connects with our prayer checkpoint: prayer is a response to God dwelling in us. We do not pray to reach a faraway God; we respond to the God who comes to live in his people.

The teaching, section by section

True freedom is more than doing whatever I want

Many people think freedom means having no limits: no rules, no obligations, no one telling us what to do. At first, that can sound attractive. But a life with no boundaries does not usually become a life of peace. It often becomes a life ruled by impulse, pressure, fear, addiction, resentment, or regret.

Catholic teaching understands freedom more deeply. Freedom is the ability to choose what is truly good. God made us with intellect, the power to know, and will, the power to choose. These gifts are not meant only for self-expression; they are meant for love. A person becomes more free, not less free, when he or she can recognize the good and choose it.

Sin does the opposite. Sin is a deliberate turning away from God’s love and from what is good. It may feel like freedom in the moment, but it makes the heart less free over time. A lie can make another lie necessary. Anger can become a habit. Selfishness can narrow the heart. God’s law names these dangers not to shame us, but to rescue us.

Key truth: True freedom is the grace-filled ability to choose the good, not merely the ability to choose anything at all.

The Old Law taught a freed people how to live

The Old Law means the law God gave to Israel, especially through Moses. Its heart is the Ten Commandments, also called the Decalogue, a word meaning “ten words.” The setting matters: God gave the commandments after he had delivered Israel from slavery in Egypt. The Law was not the price of liberation; it was guidance for people already set free.

Israel had lived under slavery for generations. They needed to learn again who God was, who they were, and how a holy people should live. The commandments taught right worship, reverence for God’s name, holy rest, family honor, respect for life, faithfulness, justice, truth, and purity of desire.

The commandments begin with God because everything else depends on worshiping the true God. If we put false gods first, whether money, success, pleasure, control, or approval, our relationships with others become disordered too. The commandments then guide love of neighbor: honoring parents, protecting life, respecting marriage, refusing theft and lies, and resisting envy.

The Sabbath is the holy day of rest. Christians keep Sunday as the Lord’s Day because Jesus rose from the dead on the first day of the week. Sunday worship and rest remind us that we are not slaves to work, achievement, or constant activity.

Key truth: God gave the Ten Commandments as a path of covenant life, teaching his people how to live in freedom with him and with one another.

The Law shows the good, but we still need a Savior

The Old Law is good. It tells the truth about God, human dignity, worship, and justice. But knowing the good is not the same as having the strength to do it. We have all experienced this: we know we should forgive, tell the truth, pray, be patient, or resist temptation, and yet we still fail.

The Church speaks of this weakness in light of sin. Original Sin means the wounded condition of the human family after the first turning away from God. We are still made good and still loved by God, but our desires, thoughts, and choices are not perfectly ordered. We need more than instruction. We need healing.

This is why the Law prepares us for Christ. The commandments show us what love requires, but they also reveal that willpower alone is not enough. We need grace, which is God’s free help and life within us. Jesus does not come to abolish what God has taught. He comes to fulfill it, to bring it to its fullness, and to free us from sin’s power.

Key truth: The Law reveals what is good, and it also reveals our need for Christ, who gives the grace to live what God commands.

The New Law is love, grace, and freedom

The New Law is the law of the Gospel: the life of Christ given to us through the Holy Spirit. It does not throw away the commandments. It fulfills them from within. The Old Law says what love must not do and what justice requires. The New Law gives the inner power to love as Christ loves.

Jesus sums up the Law in love of God and love of neighbor. This does not mean that the commandments no longer matter. It means that their deepest purpose is love. We do not avoid murder merely to “follow a rule”; we reverence the life of our neighbor. We do not avoid theft merely to stay out of trouble; we honor justice and the dignity of another person. We do not worship God alone merely because it is required; we respond to the One who made us and loves us.

The New Law is a law of love because it moves us by charity, which means self-giving love. It is a law of grace because God gives what he commands. It is a law of freedom because God does not want slaves who obey only from fear, but children and friends who are being changed from the inside.

This is also where prayer belongs. Jesus promises that the Father and the Son will dwell with the one who loves him and keeps his word. Through Christ, we are made into God’s household and a dwelling place for God. Prayer is our response to that indwelling presence: listening, surrendering, asking for help, and learning to love.

Key truth: The New Law is Christ’s own life in us, moving us by grace to love God and neighbor.

The Beatitudes show the face of Christian happiness

Beatitude means blessedness or true happiness. It is not simply feeling cheerful. It is the deep happiness of sharing God’s life. The Beatitudes are Jesus’ description of the blessed life: poverty of spirit, mercy, meekness, purity of heart, peacemaking, hunger for righteousness, and faithfulness even under persecution.

The Beatitudes do not replace the commandments. They reveal the heart that grace forms in a disciple. The commandments teach the necessary boundaries of love. The Beatitudes show love becoming beautiful in the soul.

For example:

• The commandments tell us not to worship false gods; the Beatitudes show the poor in spirit who depend entirely on God.
• The commandments tell us not to kill; the Beatitudes show the peacemakers.
• The commandments tell us not to bear false witness; the Beatitudes show disciples who remain faithful even when falsely accused.
• The commandments tell us not to covet; the Beatitudes show the meek and merciful heart that is not grasping for control.

Jesus himself is the perfect model of the Beatitudes. He is poor in spirit, meek, merciful, pure of heart, and faithful through suffering. To follow him is not simply to admire his teaching, but to receive his grace and become like him.

Key truth: The Beatitudes describe the happiness of a heart transformed by Christ.

Confession, honesty, and the Confiteor

At the beginning of Mass, the Church invites us to acknowledge our sins. One form of this is the Confiteor, a Latin word meaning “I confess.” In this prayer, we admit that we have sinned “in my thoughts and in my words, in what I have done and in what I have failed to do.”

This matters for a session on law and freedom. God’s commandments help us see not only obvious wrong actions, but also neglected love. Sometimes sin is something we did. Sometimes it is something we refused to do: a kindness withheld, a truth avoided, a duty ignored, a prayer neglected.

The Confiteor is not meant to crush us. It teaches honest humility and hope. We confess before God and before our brothers and sisters because sin wounds communion. Then we ask for prayer from Mary, the angels, the saints, and the Church. The Christian moral life begins again and again with mercy.

Key truth: Honest confession opens the heart to God’s mercy and to the freedom he wants to give.

The saint of the day

On October 28, the Church celebrates Saints Simon and Jude, Apostles. They remind us that the Christian life is received from witnesses: real people called by Jesus, sent by Jesus, and strengthened to hand on the faith. For someone in OCIA, their feast is a quiet encouragement that Christ still calls ordinary people to belong to him and to share his mission.

Taking it home

Questions to sit with

• Where do I tend to think of freedom as “doing what I want,” and where have I learned that freedom needs truth?
• Which commandment feels most challenging or most confusing to me right now?
• How might God’s law be a protection for my dignity and the dignity of others?
• Where do I know the good but struggle to do it?
• Which Beatitude most attracts me, and which one most challenges me?
• What would it mean this week to love God with more of my heart, soul, and mind?
• If God dwells in his people, how might that change the way I pray?

This week’s invitation

• Read and pray slowly with Matthew 5:1-12, asking which Beatitude Jesus is placing before you.
• Read Exodus 20:1-17 and notice that the commandments come after God’s act of liberation.
• Choose one commandment and make one concrete change this week to live it more faithfully.
• At Mass, pay attention to the Confiteor or Penitential Act, and ask God for honest humility without fear.
• Practice one act of loving service for someone at home, work, school, or in the parish.
• Spend five quiet minutes in prayer, remembering that God desires to dwell in you and teach you freedom from within.

Closing prayer

Lord God, you made me for freedom, goodness, and love.
Teach me to trust your commandments as gifts, not burdens.
Show me where sin has made my heart less free.
Give me the grace of your Holy Spirit to choose what is good.
Make my heart poor in spirit, merciful, pure, and peaceful.
Dwell in me, Lord, and teach me to respond to your presence in prayer.
Lead me in the law of Christ, the law of love.
Amen.
