sarasara, if ohzone says what you say and what actual history say are what I need to delve into for the truth....
no, that's not, actually, correct, what needs delved into is The Word, The Truth, and, it explains quite readily that the events still to come will be many per Revelation lore that is Truth and so, either believe in the sequential events to happen in the future as John wrote down in His vision from Christ, or, not.
Eusebius, Iraeneus, etc. are all just analyzational nothingness that people USE to prove their point IF the actual history bodes well of their doctrine. Yeah, true, actually

But, sad, indeed, to construct one's doctrine around what's hand-picked according to what you want to believe as Truth instead of looking to the Truth for truth. Makes sense to me, anyway.
The Lord leads.
Sorry, too, if I sound a bit snippy, I always start to go off a bit when someone accuses me of 'blasphemy,' NEVER a wise thing for one Christian to accuse of another, I don't care WHAT the scenario or contextual obligation is for the other party.
