The "absolute necessity" would be the receipt of the grace of the sacrament either in re or by votum.
I understand being done with the discussion. You express your view and clarify as necessary, then at some point it becomes redundant unless some other issue introduces itself.
Unfortunately, the absolute necessary speaks of water baptism, so no the issue of squaring is still there.
Anyway, thanks for understanding. I hope I didn't come off rude...it wasn't meant to be.
