So show me a passage in Scripture that tells us HOW to baptize. Immersion only?
Matthew 3:16 And Jesus, when he was baptized, went up straightway
out of the water: and, lo, the heavens were opened unto him, and he saw the Spirit of God descending like a dove, and lighting upon him:
Acts 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?
[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.
[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.
