It is interesting to see how the Neo-Catastrophist Henry Morris perceived Noah’s Flood — through his own spectacles of baptistic immersionism. There, he forgot it was only the unbaptized wicked who were totally submersed – and that it was only Noah’s family that was baptized, precisely by sprinkling from above.
In his book The Beginning of the World, Morris pushed his immersionistic theology. He called1 the Noachic Flood "this first great baptism" — and even "Earth’s great baptism." By this, Morris meant total submersion by a global flood — rather than the Biblical rain-sprinkling of the baptized human persons as taught in First Peter 3:20f.
