Christ died for our sins, to free us from them and redeem us from the slavery that sin introduced into mankind’s life.

The liturgy is an “action of God” that unites us to Jesus Christ through the Holy Spirit (cf. "Sacramentum Caritatis," no. 37).

God created us with the great gift of freedom. The natural law has the force of law as the voice and interpreter of the 'higher reason' of the divine Lawgiver.
Topic 28: Grace and the Virtues
Grace “is the gratuitous gift that God makes to us of his own life, infused by the Holy Spirit into our soul to heal it of sin and to sanctify it” (Catechism of the Catholic Church, 1999).

Topic 30: Personal Sin
Personal sin is an “action, word or desire contrary to the eternal law."
Topic 39: Prayer
