I am not as versed in Scripture as many of you. But, in doing some reading on it, I found that Acts 10: 47-48 and Acts 16: 29-34 appear to support baptism not involving immersion:
47 Can anyone withhold water for baptizing these people, who have received the Holy Spirit just as we have? 48 And he commanded them to be baptized in the name of Jesus Christ. Then they asked him to remain for some days.
29 And the jailer6 called for lights and rushed in, and trembling with fear he fell down before Paul and Silas. 30 Then he brought them out and said, Sirs, what must I do to be saved? 31 And they said, xBelieve in the Lord Jesus, and you will be saved, you and your household. 32 And they spoke the word of the Lord to him and to all who were in his house. 33 And he took them the same hour of the night and washed their wounds; and he was baptized at once, he and all his family. 34 Then he brought them up into his house and set food before them. And he rejoiced along with his entire household that he had believed in God.
