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

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

A deepening through CCC

(CCC 458) The Word became flesh so that thus we might know God's love: "In this the love of God was made manifest among us, that God sent his only Son into the world, so that we might live through him" (1 Jn 4:9). "For God so loved the world that he gave his only Son, that whoever believes in him should not perish but have eternal life." (Jn 3:16). (CCC 455) The title "Lord" indicates divine sovereignty. To confess or invoke Jesus as Lord is to believe in his divinity. "No one can say 'Jesus is Lord' except by the Holy Spirit'" (1 Cor 12:3).     

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 233) Christians are baptized in the name of the Father and of the Son and of the Holy Spirit: not in their names (Cf. Profession of faith of Pope Vigilius I (552): DS 415), for there is only one God, the almighty Father, his only Son and the Holy Spirit: the Most Holy Trinity.
