Catechism of the Catholic Church
The living God
205 God calls Moses from the midst of a bush that burns without being consumed: "I am the God of your father, the God of Abraham, the God of Isaac, and the God of Jacob." 9 God is the God of the fathers, the One who had called and guided the patriarchs in their wanderings. He is the faithful and compassionate God who remembers them and his promises; he comes to free their descendants from slavery. He is the God who, from beyond space and time, can do this and wills to do it, the God who will put his almighty power to work for this plan.
9 Ex 3:6.
