The "ALL" who will be resurrected must include your man made "Saints" and precludes the Bodily Assumption of any person prior to the Second Coming of Jesus.
I don't have any man made "Saints". How do you know what it precludes?
Hint: Really read, and pay attention to, the ATHANASIAN CREED which you posted.
Okay.
Who made, after an "exhaustive" process, the Saints you pray to?
Has any person ever been declared a Heretic and subsequently decrared a Saint?
Has any "Saint" ever been stricken from the roll of Saints?
MEN, not Jesus were the ones involved.
