43. 8 This faith is faith in God the Savior Jesus Christ. In a simple form it is this:

1. There is one God, the divine trinity exists within him, and he is the Lord Jesus Christ.

2. Believing in him is a faith that saves.

3. We must abstain from doing things that are evil — they belong to the Devil and come from the Devil.

4. We must do things that are good — they belong to God and come from God.

5. We must do these things as if we ourselves were doing them, but we must believe that they come from the Lord working with us and through us.

7. The teachings of the Roman Catholics on justification, as gathered from the decrees of the Council of Trent, can be linked together and summed up as follows:

The sin of Adam was transfused into the entire human race. As a result, the state of the human race and of every individual within it was ruined and alienated from God. People became enemies [of God] and children of wrath. Therefore God the Father as an act of grace sent his Son to reconcile, ritually purge, appease, make satisfaction, and thereby redeem; and to do so by becoming justice.

Christ carried out and fulfilled this task by offering himself to God the Father as a sacrifice on the wood of the cross, that is, through his own suffering and his own blood. Christ alone earned merit. God the Father through the agency of the Holy Spirit assigns, attributes, applies, and transfers this merit of Christ’s to receptive individuals as an act of grace. In this way the sin of Adam is removed from them, although cravings do nonetheless remain and entice them to sin.

Justification is the forgiving of sins, which leads to a renewal of the inner self, by which we turn from an enemy [of God] into a friend and from a child of wrath into a child of grace. This brings us into a union with Christ. We are reborn as a living part of his body.
