Epiphanius of Salamis: No One Knows the End of Mary

Epiphanius of Salamis (310/320-403): And there have been many such things to mislead the deluded, though the saints are not responsible for anyone’s stumbling; the human mind finds no rest, but is perverted to evils. The holy virgin may have died and been buried—her falling asleep was with honor, her death in purity, her crown in virginity. Or she may have been put to death—as the Scripture says, “And a sword shall pierce her soul”— her fame is among the martyrs and her holy body, by which light rose on the world, [rests] amid blessings. Or she may have remained alive, for God is not incapable of doing whatever he wills. No one knows her end.
But we must not honor the saints to excess; we must honor their Master.
