Правила архиепископа Петра Александрийского (из его слова о покаянии) Правило 1 Петра Александрийского

Since the fourth Easter after the persecution is already approaching, the time of excommunication is upon those who were subjected to denunciation, were imprisoned, suffered cruel torment and unbearable wounds, and many other grave oppressions, and who were finally betrayed by the weakness of the flesh. Although at first they were not accepted into the church, due to the grave fall that followed: but since they labored a lot and fought for a long time (since they reached the point of crime not out of arbitrariness, but because the weakness of the flesh betrayed them, for they show the wounds of Jesus on their bodies, and some have been in mourning for the third year already), then let another fourty days be added to this penance, according to mindfulness when they approached the church. For the same number of days, our Lord and Savior Jesus Christ, after baptism, having fasted, was tempted by the devil: for the same number of days, let them strive and fast more diligently, and moreover, let them stay awake in prayer, constantly meditating on what was spoken by the Lord to the tempter, who demanded of Him to worship himself: follow me, Satan, for it is written: Thou shalt worship the Lord thy God, and serve only that one (Matthew 4:10). (Ap. 62; I Om. 10; Ankyr. 4; Gregory of Nyssk. 2). The present and the following 13 rules, called in the Latin editions canones poenitentiales, are compiled from the word of Peter on repentance (περί μετανοίας), written in Alexandria in the 4th year of the Maximinian persecution, or in the year 306 of the Christian era, for those who fell during the persecution, and it is prescribed how They must be subjected to penance. All these rules of St. Peter of Alexandria contain in general the same thing as the first 9 rules of the Ancyra Council, which had its meetings only 8 years after this holy father wrote his word on repentance, from which these rules are compiled. In the interpretations of the mentioned Ancyra rules, we spoke enough about those who, during the persecution, apostatized from Christianity, about the degrees and methods of their apostasy, as well as about the punishments that should be subjected to subsequently, when the persecution stopped and they returned to Christianity again. As a result of this, we leave all 14 rules of this holy father without special interpretations, for the mentioned interpretations of the corresponding Anchir rules serve at the same time as interpretations of these rules. We presented a systematic presentation of the teaching of the Orthodox Church on apostasy from Christianity in another place 130. See mine: “Crkveno executed right” (Mostar, 1911), pp. 344–352.
