YOUCAT Question n. 76 - Part V. Why did God become man in Jesus?

(Youcat answer - Repeated) “For us men and for our salvation he came down from heaven” (Nicene Creed).      

A deepening through CCC

(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. (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).     

Reflecting and meditating 

(Youcat comment) In Jesus Christ, God reconciled the world to himself and redeemed mankind from the imprisonment of sin. “God so loved the world that he gave his only-begotten Son” (Jn 3:16). In Jesus, God took on our mortal human flesh (incarnation), shared our earthly lot, our sufferings, and our death, and became one like us in all things but sin.

(CCC Comment)

(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).    

(The next question is: What does it mean to say that Jesus Christ is at the same time true God and true man?)
