Not exactly. Baptism communicates death to one's old life, and new life in Christ. So, a funeral and a (re)birth, all in one.Solid black suits are acceptable for funerals, but Baptisms are the polar opposite of funerals.
I think the reason your point is not being addressed to your satisfaction is that it's not a logical premise to begin with. A wedding or a funeral would no doubt be a more significant event than a business meeting, but I may wear the same suit to all of these, and be perfectly appropriately dressed in each case. There aren't enough modes of dress to be able to match each level of "event significance" to a different mode of dress. The fact that you can't wrap your head around something so obvious is the reason some have thrown out the T word.I guess that is the point I'm trying to make here, and which I have not yet seen addressed by any of the posters. If the accepted wisdom is that a suit and tie is an acceptable form of dress for mass, what is the rationale for suggesting it as the form of dress for an event which is more significant than a regular mass?
