Правило 4 Дионисия Александрийского

Those who have experienced an involuntary nocturnal discharge should also follow their conscience and examine themselves whether this is why they are in doubt or not: just as the apostle says about food: he who doubts, if he eats, is condemned (Rom. 14:23). And in this case, let everyone who approaches God have a good conscience and good courage, according to his own thoughts. You, beloved, have proposed these questions to us, as if you honor us (for without a doubt, not as if you do not know), disposing us to be like-minded and unanimous with you, just as we are. Not like a teacher, but since it is decent for us to talk to each other, with all simplicity, I offered my opinion on Wednesday. Think about this, my most prudent son, and write to me if something fair and better presents itself to you, or if you see such a thing to happen. I wish you, my beloved son, good health and serve the Lord in peace. (Ankyr. 23; Athanasius Vel. 1; Timothy Alex. 12). By involuntary nocturnal emission, which this rule speaks of, we must understand the emission of semen (σπέρματος). In the first rule of Athanasius the Great, otherwise in his letter to Ammun, it is called φυσική Ικκρισις (naturalis excretio), and this is discussed in more detail here. Regarding this cf. Zonars 124, equal to Balsamon's 10th canonical answer 125. The second half of this rule is the end of Dionysius’ letter to Bishop Basilides. Af. Synth., IV, 455. See also Harmenop., Epit. Can., sect. 5, tit. 2 (Leunclav., I, 51). You might be interested in:
