Послание 3 Григория Нисского

Those who come to sorcerers or soothsayers, or to those who promise to perform some kind of cleansing or aversion of harm through demons, are asked in detail and tested: whether, while remaining in faith in Christ, they are drawn by some need to such sin, in the direction given to them by some misfortune or unbearable deprivation, or, having completely despised the confession entrusted to them from us, have resorted to help demons. For if they did this with a rejection of faith, and in order not to believe that God is worshiped by Christians, then without a doubt they will be subject to condemnation with apostates. If unbearable need, having taken possession of their weak soul, brought them to this point, seducing them with some false hope, then let love for mankind be shown to them too, in the likeness of those who, during confession, were unable to resist torment. (Trul. 61, 65; Ancir. 24; Laod. 36; Basil the Great. 65, 72 and 83). You might be interested in:
