43. What does it mean to believe in only one God?

(Comp 43) To believe in the one and only God involves coming to know his greatness and majesty. It involves living in thanksgiving and trusting always in him, even in adversity. It involves knowing the unity and true dignity of all human beings, created in his image. It involves making good use of the things which he has created.

“In Brief”

(CCC 229) Faith in God leads us to turn to him alone as our first origin and our ultimate goal, and neither to prefer anything to him nor to substitute anything for him.

To deepen and explain

(CCC 222) Believing in God, the only One, and loving him with all our being has enormous consequences for our whole life. (CCC 223) It means coming to know God's greatness and majesty: "Behold, God is great, and we know him not" (Job 36:26). Therefore, we must "serve God first" (St. Joan of Arc). (CCC 225) It means knowing the unity and true dignity of all men: everyone is made in the image and likeness of God (Gen 1:26). (CCC 226) It means making good use of created things: faith in God, the only One, leads us to use everything that is not God only insofar as it brings us closer to him, and to detach ourselves from it insofar as it turns us away from him: My Lord and my God, take from me everything that distances me from you. My Lord and my God, give me everything that brings me closer to you. My Lord and my God, detach me from myself to give my all to you (St. Nicholas of Flue; cf. Mt 5:29-30; 16:24-26).

On reflection

(CCC 224) It means living in thanksgiving: if God is the only One, everything we are and have comes from him: "What have you that you did not receive?" (1 Cor 4:7). "What shall I render to the LORD for all his bounty to me?" (Ps 116:12). (CCC 227) It means trusting God in every circumstance, even in adversity. A prayer of St. Teresa of Jesus wonderfully expresses this trust: Let nothing trouble you / Let nothing frighten you Everything passes / God never changes Patience / Obtains all Whoever has God / Wants for nothing God alone is enough (St. Teresa of Jesus, Poesias 30 in The Collected Works of St. Teresa of Avila, vol. III, tr. K. Kavanaugh OCD and O. Rodriguez OCD (Washington DC Institute of Carmelite Studies, 1985), 386 no. 9. tr. John Wall).
