Правило 10 Святых Апостолов

If anyone prays with someone who has been excommunicated from church communion, even if it was in the house, let him be excommunicated. (Ap. 11, 12, 32, 45, 48, 65; I Om. 5; Antioch. 2; Carth. 9). The excommunication that we talked about in our interpretation of the 5th Ap. rules (Ap. 5), as a punishment depriving of communication with a certain society, occurs by itself, if only one certain higher principle dominates in a given society, which must be sacredly protected by certain means to maintain the society itself. This happens in general and in any society with a lofty goal, and especially this happens and should be in a religious society. We find the same thing among both pagans and Jews, who deprived unworthy members of their religious community of prayerful communication with the rest of the faithful brethren, i.e. excommunicated them from their religious society 148. In the Christian Church this was observed even more strictly. Jesus Christ Himself initiated the excommunication from His church, saying: “If he does not listen to the church, then let him be to you as a pagan and a tax collector” (Matthew 18:17), i.e. in other words, let him be excommunicated. Subsequently, the Apostles explained this in detail in their epistles, and also applied it in practice (1 Cor. 5:5; 1 Tim. 1:20; 2 Tim. 3:5; Titus 3:10; 2 Sol. 3:6; 2 John 1:10, 11). Thus, the rule strictly expresses the thought of Holy Scripture, forbidding praying with someone who has been excommunicated from church communion, not only in church, when there is prayer common to all the faithful, but even at home alone with someone who has been excommunicated from the church. The same thought of Holy Scripture is expressed by the rule, prescribing excommunication from the church of everyone who will have prayerful communication with someone whom the church authorities have excommunicated from their fellowship. We find such a teaching of the church on excommunications in the works of St. fathers and teachers of the church of ancient times 149. Wed. Beveregii, Annotat. in h. can. (page 21). Ap. post., VIII, 34. – Tertull. apol. With. 39 [Migne, s. l., t. 1, col. 467–448]. – Cyprian. epist. 28, 38, 62, 65 [Migne, s. l., t. 4, col. 300–302; 329–331; 364–372; 393–397]. “It is allowed to talk with those excommunicated from church communion only about non-church matters,” they say in Balsamon’s interpretation of the 10 rights. (Af. Synt., II, 14) and Vlastar in his Syntagma A, 18 (Af. Synt., VI, 107). You might be interested in:
