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 2063
The covenant and dialogue between God and man are also attested to by the fact that all the obligations
are stated in the first person (“I am the Lord.") and addressed by God to another personal subject (“you"). In
all God's commandments, the singular personal pronoun designates the recipient. God makes his will known
to each person in particular, at the same time as he makes it known to the whole people:
The Lord prescribed love towards God and taught justice towards neighbor, so that man would be neither unjust, nor unworthy of God. Thus, through the Decalogue, God prepared man to become his friend and to live in harmony with his neighbor.... the words of the Decalogue remain likewise for us Christians. Far from being abolished, they have received amplification and development from the fact of the coming of the Lord in the flesh.26
