Правило 20 Василия Великого

If any of the female sex, having been in heresy, took a vow of virginity, but then chose marriage: of such I think that it is not proper to condemn them: the law, if it says anything, speaks to those who are under the law (Rom. 3:19). But those who have not yet taken upon themselves the yoke of Christ do not know the law of the Lord. Therefore, they can be accepted into church with everyone, and in this case they receive forgiveness through the acceptance of faith in Christ, and in general, everything done in the life of the catechumens is not subject to torture. It is obvious that the church does not accept such people without baptism: therefore, the most necessary need for them is the benefits of rebirth. (I Om. 14; II Om. 7; Neokes. 5; Laod. 19; Timothy Alex. 6; Cyril Alex. 5). In order for any vow to be recognized by the church, it must be made in the church and according to the rules of the church; a vow made by someone who does not belong to the church, and, therefore, given outside the church, has no force for the church, which is why the violation of such a vow is not subject to church punishment. Asked about the vow of virginity given by a woman who belonged to a heretical society and then broke it by marrying, subsequently leaving the heresy and wishing to accept Orthodoxy, Basil the Great quotes the words of the Apostle Paul, according to which the law, if it says anything, speaks to those who are under the law (Rom. 3:19), and, therefore, those who are outside this law, who do not profess the Orthodox faith, are not bound by the law, which they do not know; according to this, he decides that the mentioned wife can be accepted into the church, since by faith in Christ she receives forgiveness of all sins, including the above. Saint Basil here mentions baptism and, therefore, has in mind heretics who can be received into the church only through the sacrament of baptism (II Om. 7). You might be interested in:
