Ο Όσιος Ιωάννης ήταν Επίσκοπος Ειρηνουπόλεως (η Ειρηνούπολη, πόλη Βυζαντινή, ήταν κοντά στον ποταμό Σάρο και το βουνό Ταύρος της Τραχείας Κιλικίας) και ένας από τους τριακόσιους δέκα οκτώ (318) Αγίους Πατέρες της Α' Οικουμενικής Συνόδου, που συνήλθε στη Νίκαια της Βιθυνίας, το έτος 325 μ.Χ., για να καταδικάσει τις αιρετικές δοξασίες του Αρείου. Ο Όσιος Ιωάννης κοιμήθηκε οσίως με ειρήνη.
