On Sinlessness and Mortality

St. Athanasius the Great ca. 297-373

Many for instance have been made holy and clean from all sin; nay, Jeremiah was hallowed even from the womb, and John, while yet in the womb, leapt for joy at the voice of Mary Bearer of God; nevertheless ‘death reigned from Adam to Moses, even over those that had not sinned after the similitude of Adam’s transgression Rom. 5:14;’ and thus man remained mortal and corruptible as before, liable to the affections proper to their nature. (Four Discourses Against the Arians, Discourse 3.33)
