OK you’re saying that she died. I’m confused because the early church father Epiphanus, in 377 AD stated:
- “If* the Holy Virgin had died and was buried, her falling asleep would have been surrounded with honour, death would have found her pure, and her crown would have been a virginal one…Had she been martyred according to what is written: ‘Thine own soul a sword shall pierce’, then she would shine gloriously among the martyrs, and her holy body would have been declared blessed; for by her, did light come to the world.” Epiphanius,Panarion,78:23(A.D. 377),in PG 42:737
“
Did she die? We do not know. At all events, if she was buried, she had no carnal intercourse. . . . Or she remained alive, since nothing is impossible with God and he can do whatever he desires” (Panarion, haer. 78, nn. 10-11,23: G.C.S., 37, 461-462; 474).
Also, you say that after Mary died in her tomb, she assumed into Heaven, and all this information was passed down apostolically.
So where is the exact location of her tomb where she assumed from located? This should be an extraordinary place of veneration for Catholics. (They knew where Peter died and so they built St. Peter’s Basilica over it. I would imagine they would do the same for someone deserving higher veneration)
