I’m having trouble with this passage, but here goes …
“Now therefore the whole nation of Israel must know beyond the shadow of a doubt that this Jesus, whom you crucified, God has declared to be both Lord and Christ.”
… It seems that Peter is basing his arguments for Jesus being the messiah on two things – one, the prophesies from the OT, the other, the miracles J performed.
1)this is something which was predicted by the prophet Joel …. David …. He foresaw the resurrection of Christ, and it is this of which he is speaking.
… I find these references to the OT less than convincing, though I can understnad the necessity of it …. By stressing the continuity between Judaism and Christianity, Luke argues that Christianity is deserving of the same toleration accorded Judaism by Rome. – NAB. And Luke also uses this device to identifies Peter with jesus …. Peter preaches, quoting from the prophet Joel (2:16-36; quoting Joel 2:28-32) – Jesus preaches, after reading from the prophet Isaiah (4:14-30; quoting Isa 61:1-2) – Felix Just SJ
2)Jesus of Nazareth was a man proved to you by God himself through the works of power, the miracles and the signs which God showed through him here amongst you …
… this I do find a fairly convincing proof of Jesus being God … not so much the healings, which other Rabbis at the time also performed, but Jesus’ ability to still a storm, walk on water, bring the dead back to life, etc. I know most don’t believe in the existence of the miracles of the gospels, but I’m sticking with being a supernaturalist :-).
