Article 1 IN THE OLD TESTAMENT

From The Catechism of the Catholic Church

2569
Prayer is lived in the first place beginning with the realities of creation.
the first nine chapters of Genesis describe this relationship with God as an
offering of the first-born of Abel’s flock, as the invocation of the divine
name at the time of Enosh, and as “walking with God.⁵ Noah’s
offering is pleasing to God, who blesses him and through him all creation,
because his heart was upright and undivided; Noah, like Enoch before him,
“walks with God.”⁶ This kind of prayer is lived by many
righteous people in all religions.
In his indefectible covenant with every living creature,⁷ God has
always called people to prayer. But it is above all beginning with our father
Abraham that prayer is revealed in the Old Testament.
