The Messiah of Prophecy
And why did God decide to send a Redeemer??
In brief:
Catechism of the Catholic Church:
622 The redemption won by Christ consists in this, that he came “to give his life as a ransom for many” (Mt 20:28), that is, he “loved [his own] to the end” (Jn 13:1), so that they might be “ransomed from the futile ways inherited from [their] fathers” (I Pt 1:18).
623 By his loving obedience to the Father, “unto death, even death on a cross” (Phil 2:8), Jesus fulfills the atoning mission (cf. Is 53:10) of the suffering Servant, who will “make many righteous; and he shall bear their iniquities” (Is 53:11; cf. Rom 5:19).
