What is the definition of "real and natural water" for a valid baptism performed by the laity? Is tap water ok? Bathtub water? River? Ocean?
Also, when the person performing the baptism pours the water over the head of the other person does the water have to be flowing throughout the baptism?
Or could he say I baptize you in the name of the father (pour water, stop),. the son (pour water again, stop), and the holy ghost (pour water, stop)?
Finally, is it acceptable to pour on the hair as long as just a little bit of water drips down to the forehead?
