From the Constitutions of St. Nicephorus, Bishop of Constantinople, who Died A.D. 828

(Cf. Spicilegium Solesmense, Tom. IV, p. 397 and following.)

From the fourth Sylloge of Canons. Canon XXXIV. If anyone, having obtained a concubine, does not wish either to dismiss her or to have her blessed and to have her rightly with the sacrament, it is not fitting that those things which are offered by him to the Church be received.

Canon XXXV. If a monk, after putting aside the holy habit, has eaten flesh and led a wife, it is fitting that he be converted; if he is unwilling, that he be subjected to anathema and clothed, unwilling, with monastic garments and shut up in a monastery.

Therefore also among the Greeks there was no such marriage.

From the seventh Sylloge. Canon I. If anyone is bound by spiritual affinity, or if anyone baptizes a boy who afterward, having become a man, has a sister, but he who receives the boy, after being made a widower, turns himself hither so that he may lead as wife (the sister?) of his godson, he has penance of 5 years.

Canon VIII. One entangled in fourth nuptials is indeed outside the law and is banished from the ecclesiastical boundary; for polygamy and uncleanness are held by the most holy Fathers; nevertheless he will have penance of 7 years.

Cf. what was said in Thesis XII, nn. VI, VII, VIII.
