Clowns are a red herring and have nothing to do with the topic at hand.
There are three issues here:
- The mode of baptism
- The place of baptism
- Celebrating after the baptism
As for the mode of baptism, it is an adiaphoron: sprinkling, pouring, immersing are all valid. If this woman has confessed Christ, and has confessed a proper understanding of baptism, then she is in no way, shape, or form out of line in requesting to be immersed. For anyone to suggest that she is behaving incorrectly is to return to the Babylonian Captivity, i.e., "If you're really Lutheran, you'll do it the way we all did it!"
Bollocks!
Speaking of Babylonian Captivity, someone earlier pointed out that Luther himself preferred immersion, which is true. The relevant citation is from paragraph 23 of section three of On the Babylonian Captivity of the Church:
(I always find it amusing when Baptists want to use this statement against Lutherans, considering that Luther is using this as an argument for baptismal regeneration, but that's beside the point...)
As for the place, well, Lutheran architecture being what it is, immersion is generally out of the question, since we don't include baptismal pools in our churches. That leaves another Church or some other body of water. Since there is no Biblical mandate requiring that anyone be baptized in a sacred space (doing things in an "orderly" manner can in no way be equated with "in a sacred space"), and in fact there are many baptisms done in odd places (rivers, homes (Acts 10), in random bodies of water by the side of the road (Acts 8), possibly in a jail (Acts 15)), then we can only conclude that the place of baptism is also an adiaphoron.
As for the timing of the event, I turn back to Luke 15. The shepherd doesn't even go back to round up his other 99 sheep before he invites his friends to celebrate. There has been nothing in TCat's description which imply everyone will be hanging out in their speedos and bikinis drinking margaritas while her friend is being dunked. You have imputed that mental picture (or something like it) to the situation, with absolutely no evidence to back it up. That is most certainly not putting the best construction on things.
It's just my opinion, but I think you are picking where there are no nits.
