I just did it a month ago when Gerald Spade wanted to be baptized and join this church. He was too ill to be baptized by immersion. So I had the choice either not baptize him at all or to baptize him in something less than total immersion. It was more important that he be baptized than that it be done by immersion. So pouring water over his head and baptized him as a believer in Jesus Christ.
Baptism is a symbol or sign.
It signifies a spiritual reality beyond itself. We call it an ordinance. Baptists do not call it a sacrament. We do not believe that baptism saves you. Most Baptists believe that baptism is a sign or symbol of the salvation that we received when we first accepted Jesus Christ as Savior.
