Who they were

At Constantinople, Saint Alexander, bishop, whose apostolic prayer, as Saint Gregory of Nazianzus writes, crushed the head of Arian impiety.

There was never a formal cause: he has been honoured as a saint since before the Church's formal processes began.

Why that counted as sanctity

The Roman Martyrology remembers him on 28 August as a bishop of Constantinople whose prayer overcame the Arian heresy.
