Beginning from the baptism of John, unto that same day that he was taken up from us, must one be ordained to be a witness with us of his resurrection.
Read Chapter 1
John Chrysostom
AD 407
He did not say, a witness of the rest of his actions, but a witness of the resurrection alone. For indeed that witness had a better right to be believed, who was able to declare, that He Who ate and drank, and was crucified, the same rose again. Wherefore it was needed that he should be a witness, not only of the time preceding this event, nor only of what followed it, and of the miracles; the thing required was, the resurrection. For the other matters were manifest and acknowledged, but the resurrection took place in secret, and was manifest to these only.
