Catechism of the Catholic Church

The Profession of Faith 55 all nations to turn to him, the one and only God: “Turn to me and be saved, all the ends of the earth! For I am God, and there is no other . . . . To me every knee shall bow, every tongue shall swear. ‘Only in the Lord , it shall be said of me, are righteousness and strength.’” 5 202 Jesus himself affirms that God is “the one Lord” whom you must love “with all your heart, and with all your soul, and with all your mind, and with all your strength.” 6 At the same time Jesus gives us to understand that he himself is “the Lord.” 7 To confess that Jesus is Lord is distinctive of Christian faith. This is not contrary to belief in the One God. Nor does believing in the Holy Spirit as “Lord and giver of life” introduce any division into the One God: We firmly believe and confess without reservation that there is only one true God, eternal, infinite ( immensus ) and un- changeable, incomprehensible, almighty, and ineffable, the Father and the Son and the Holy Spirit; three persons indeed, but one essence, substance or nature entirely simple. 8 II. G od R eveals H is N ame 203 God revealed himself to his people Israel by making his name known to them. A name expresses a person’s essence and identity and the meaning of this person’s life. God has a name; he is not an anonymous force. To disclose one’s name is to make oneself known to others; in a way it is to hand oneself over by becoming accessible, capable of being known more intimately and addressed personally. 204 God revealed himself progressively and under different names to his people, but the revelation that proved to be the fundamental one for both the Old and the New Covenants was the revelation of the divine name to Moses in the theophany of the burning bush, on the threshold of the Exodus and of the covenant on Sinai. 5 Isa 45: 22-24; cf.
