If it's OK for someone other than Ambrose and Mary to interject an opinion

, here's mine:
One of the reasons I'm more comfortable with Orthodoxy than Catholicism is my perception that Orthodoxy is, at least in theory, more comfortable with my uncertainty about the afterlife.
There may very well be something like Purgatory after we die. But I haven't died yet, so I don't know.
There may very well be something like Toll Houses after we die. But I haven't died yet, so I don't know.
There may be something completely different and unexpected after we die.
There may be NOTHING after we die.
But I haven't died yet! So I don't know!!!
And I don't really see how anyone who hasn't died can know, for sure, to the point where they can authoritatively tell other people that they MUST believe what they believe, as a FACT, or else they will be shut out from any contact with God for eternity.
Sigh. So what do you think? Am I doomed?

Are you suggesting that comfort is the arbiter of theological truth?
Also, logically and without immediate reference to your wide ranging doubts, has it occurred to you that among the substances of things unseen are such gems as....heaven....and howse'bout the resurrection of the body?...all those credal truths, and such.
If you are right about Orthodoxy not being certain about some of these fundamentals then I suppose that's where you belong.
I don't think that's true BTW...so maybe you still belong there but I'd re-think my reasons.
