I'll repeat myself. Do you believe in Purgatory?
Well, the link referenced sure didn’t give Luther any chance at Purgatory if it exists.
...which raises the recurring question of: if everyone not positively & perfectly confessing Christ gets a “second chance” at the Cosmic Washing Machine of Purgatory as a route to Heaven, then how does anyone end up in Hell? Christ made clear that no sin was greater than another*, that any sin committed whatsoever condemns one to eternal damnation - that’s rather counter to the whole concept/purpose of Purgatory.
(* - yes there’s one narrow arguable exception. I’m waiting for you to fall into that trap; it will mean more to you then.)
