|Hairy naked baptism. 3rd century naked was like 1970's naked.|
But ritually, the immersion baptism can be a bit of a mess. And methinks that ritually it also becomes somewhat an unnecessary distraction. The main event of the Vigil is the dunking rather than the richness of each sacrament and the solemnity of it all. I am pretty sure (but am open to correction) that the early immersion baptisms weren't public due to the catechumen (the one to be baptized) being buck-nekkid and dunked in the water then clothed in the white baptismal gown. It also is written that the baptism of the aforementioned naked person was done in a darkened baptistry to hide the nakedness (but it's not like a big deal, we're talking 3rd century naked which is probably not as HAWT as you'd think. If you think). It also was dark to show that the initiated enters in darkness and emerges with light. If not in a darkened room, it certainly wasn't an occasion for everyone to see. Only a few witnesses and of the same gender as the baptized, I believe, were there. So the rite still retained some gravitas.
