Paul taught baptism in water was important--
Act 22:16 And now why tarriest thou? arise, and be baptized, and wash away thy sins, calling on the name of the Lord.
Act 19:3 And he said unto them, Unto what then were ye baptized? And they said, Unto John's baptism.
Act 19:4 Then said Paul, John verily baptized with the baptism of repentance, saying unto the people, that they should believe on him which should come after him, that is, on Christ Jesus.
Act 19:5 When they heard this, they were baptized in the name of the Lord Jesus.
Act 19:6 And when Paul had laid his hands upon them, the Holy Ghost came on them; and they spake with tongues, and prophesied.
1Co 1:13 Is Christ divided? was Paul crucified for you? or were ye baptized in the name of Paul?
1Co 1:14 I thank God that I baptized none of you, but Crispus and Gaius;
1Co 1:15 Lest any should say that I had baptized in mine own name.
1Co 1:16 And I baptized also the household of Stephanas: besides, I know not whether I baptized any other.
Philip taught the same--
Act 8:4 Therefore they that were scattered abroad went every where preaching the word.
Act 8:5 Then Philip went down to the city of Samaria, and preached Christ unto them.
Act 8:6 And the people with one accord gave heed unto those things which Philip spake, hearing and seeing the miracles which he did.
Act 8:7 For unclean spirits, crying with loud voice, came out of many that were possessed with them: and many taken with palsies, and that were lame, were healed.
Act 8:8 And there was great joy in that city.
Act 8:12 But when they believed Philip preaching the things concerning the kingdom of God, and the name of Jesus Christ, they were baptized, both men and women.
Act 8:14 Now when the apostles which were at Jerusalem heard that Samaria had received the word of God, they sent unto them Peter and John:
Act 8:15 Who, when they were come down, prayed for them, that they might receive the Holy Ghost:
Act 8:16 (For as yet he was fallen upon none of them: only they were baptized in the name of the Lord Jesus.)
Act 8:17 Then laid they their hands on them, and they received the Holy Ghost.
(same as did Paul in Acts 19.)
Act 8:35 Then Philip opened his mouth, and began at the same scripture, and preached unto him Jesus.
Act 8:36 And as they went on their way, they came unto a certain water: and the eunuch said, See, here is water; what doth hinder me to be baptized?
Act 8:37 And Philip said, If thou believest with all thine heart, thou mayest. And he answered and said, I believe that Jesus Christ is the Son of God.
Act 8:38 And he commanded the chariot to stand still: and they went down both into the water, both Philip and the eunuch; and he baptized him.
Act 8:39 And when they were come up out of the water, the Spirit of the Lord caught away Philip, that the eunuch saw him no more: and he went on his way rejoicing.
