Constantine the Jew

Constantine the Jew (c. 850[1] – 26 December, after 886) was a Byzantine Christian monk and evangelist venerated as a saint within his monastic milieu and in Constantinople.

[3] Constantine's family arranged a marriage for him, but on his wedding day he fled to the monastery of Phlouboute, where he was finally baptised.

[2] Constantine, known as "the former Jew" (ό εξ Ιουδαιων, ho ex Iudaion),[3] remained at Phlouboute for twelve years.

[2][1] An anonymous hagiography of Constantine (Acta Sanctorum, Nov. IV, 628–656[3] and Bibliotheca Hagiographica Graeca 370[4]) was written by a Nicaean monk early in the tenth century during the reign of Leo VI,[2] probably in Constantinople.

[2] Archbishop Anthony of Novgorod records the existence of a church dedicated to Constantine in the Jewish Quarter of Constantinople in the thirteenth century.
