Acts 4:9

If we this day are examined concerning a good deed done to an impotent man, by what means this man is made whole; be it known unto you all, and to all the people of Israel, that in the name of Jesus Christ of Nazareth, whom ye crucified, whom God raised from the dead, even in him doth this man stand here before you whole.

Peter moved quickly to the attack, charging the Sanhedrin with murdering the Son of God, and affirming that the great miracle in view had been accomplished by the authority of that same Christ whom they had crucified.

In him doth this man stand ... If we may rely upon the English Revised Version (1885) rendition here, it may be assumed that the man had been baptized into Christ since the miracle was wrought; because the New Testament reveals no other device by which any man was accounted to be "in Christ." See Romans 6:3,1 Corinthians 12:13, and Galatians 3:27. If this is allowed, and we believe it should be, then Peter's words emphasized the fact of the spreading kingdom and the multiplication of disciples mentioned by Luke a bit earlier (Luke 4:4), This, of course, would have further infuriated the Sadducees.
