Canon V.

Let none of those who are on the priestly list possess any woman or maid servant, beyond those who are enumerated in the canon as being persons free from suspicion, preserving himself hereby from being implicated in any blame.  But if anyone transgresses our decree let him be deposed.  And let eunuchs also observe the same rule, that by foresight they may be free of censure.  But those who transgress, let them be deposed, if indeed they are clerics; but if laymen let them be excommunicated.

Notes.

Ancient Epitome of Canon V.

A priest, even if a eunuch, shall not have in his house a maid or other woman except those on whom no suspicion can light.

See Canon III., of First Ecumenical Council at Nice.  This canon adds Eunuchs.
