Unto what then were ye baptized? What doctrine did you make profession of? And what religion did you seal unto at your baptism? Unto John's baptism; the doctrine that John taught, and the religion that he professed and preached. Thus the Jews are said to be baptized unto Moses, 1 Corinthians 10:2, being engaged to believe the doctrine and observe the law delivered by Moses. Now the Baptist, as Acts 18:25, preached indeed Christ; but many things concerning him he could not preach, unless as of things to come; as his death, and resurrection: the Baptist being beheaded before our Saviour's death, and the Holy Ghost was not poured out in that extraordinary manner until after our Saviour's resurrection and ascension; which pouring out of the Spirit, these disciples at Ephesus, having been baptized by John in Judea, and afterwards returning home, might not have heard of.
