He examines the speeches in Acts and also the editorial skeleton in Mark, and he finds that they follow a more or less common pattern: the ministry began with the «
baptism» of John, that is, his
message of repentance and work as a baptizer; following John's arrest, Jesus began his own ministry in Galilee, and there «went
about doing good,» and «healing all that were possessed by the devil»; then he came up to Jerusalem, where the rulers put him to death by crucifixion; on the third day he rose again, and appeared to his disciples, who were now «witnesses» to the truth of these reported events, namely to his resurrection from the dead.
And the Jewish people who heard the
message of Peter and who wanted to participate with this arrival of the Kingdom of God in Jesus Christ indicated this desire publicly by receiving the
baptism of repentance for the remission of sins, just as others had done with John
about three years earlier.
