How did the early Jewish-Christians view Jesus' resurrection?
Ye men of Israel, hear these words; Jesus of Nazareth, a man approved of God among you by miracles and wonders and signs, which God did by him in the midst of you, as ye yourselves also know:
Him, being delivered by the determinate counsel and foreknowledge of God, ye have taken, and by wicked hands have crucified and slain:
Whom God hath raised up, having loosed the pains of death: because it was not possible that he should be holden of it.
(Acts 2:22-24)
The early Christians assumed Jesus had been raised by God, and not that he was God.
