506 Part Three 2085 The one and true God first reveals his glory to Israel. 6 The revelation of the vocation and truth of man is linked to the revela­ tion of God. Man’s vocation is to make God manifest by acting in conformity with his creation “in the image and likeness of God”: There will never be another God, Trypho, and there has been no other since the world began . . . than he who made and ordered the universe. We do not think that our God is different from yours. He is the same who brought your fathers out of Egypt “by his powerful hand and his out­ stretched arm.”We do not place our hope in some other god, for there is none, but in the same God as you do: the God of Abraham, Isaac and Jacob. 7 2086 “The first commandment embraces faith, hope, and char­ ity. When we say ‘God’ we confess a constant, unchangeable being, always the same, faithful and just, without any evil.

St. Paul speaks of the “obedience of faith” 9 as our first obligation. He shows that “ignorance of God” is the principle and explanation of all moral deviations. 10 Our duty toward God is to believe in him and to bear witness to him. 2088 The first commandment requires us to nourish and protect our faith with prudence and vigilance, and to reject everything that is opposed to it. There are various ways of sinning against faith: Voluntary doubt about the faith disregards or refuses to hold as true what God has revealed and the Church proposes for belief. Involuntary doubt refers to hesitation in believing, difficulty 6 Cf.
