Nisi quis renatus fuerit ex aqua, et spiritu sancto, non potest introire in regnum Dei.
unless a man be born again of water and the Holy Ghost, he cannot enter into the kingdom of God.
John 3.5
Ecce aqua, quid prohibet me Baptizari?
See, here is water: what doth hinder me from being baptized?
Acts 8.36
