Note 5 at Ac 11:18: The account of Cornelius' water baptism is noticeably missing from Peter's arguments. If water baptism was necessary for forgiveness of sins, as some teach, it wouldn't have mattered that an angel spoke to Cornelius or that they had received the Holy Ghost or that anything else happened, if they didn't receive water baptism. Peter omitting their water baptism illustrates that the early church did not believe water baptism was essential for salvation (see note 9 at Mr 16:16 and note 2 at Ac 2:38).
