one baptism
Ephesians 4:5
4:5 one baptism. Whether this “one baptism” refers to Spirit baptism or water baptism has been extensively argued. Since both aspects of baptism are taught in the Bible, with water baptism being the visible sign and testimony to the Spirit’s baptism, and since no modifying words or phrases are attached to the word here to identify it as one or the other, it is probable that both aspects are in view, it being implicit that both go together in one unifying reality. See notes on I Corinthians 12:13 and Romans 6:3-5.
