Since there was a passing from the paradise of freedom to the slavery of this world, in punishment for sin, the first phrase of the Decalogue, the first word of God's commandments, bears on freedom "I am the LORD your God, who brought you out of the land of Egypt, out of the house of slavery." 25
Catechism number 2062
The Commandments properly so-called come in the second place: they express the implications of
belonging to God through the establishment of the covenant. Moral existence is a response to the Lord's
loving initiative. It is the acknowledgement and homage given to God and a worship of thanksgiving. It is
cooperation with the plan God pursues in history.
