Правило 71 Василия Великого

Anyone who has been exposed to any of the above-mentioned sins, and has not confessed, but has been convicted, may be subject to penance for the same amount of time as the doer of evil is subject to penance. This rule is the completion of the previous rules (51-70) about various sins mentioned in these rules, and anyone who knows about sins committed by someone and does not want to inform the bishop about it, but hides and condones the sinner, the rule subjects to the same punishment as those who committed this sin. This rule contains a very important definition of general criminal law. For the crimes listed in the previous rules, the perpetrators are subject to established penalties; but those involved in these crimes are also subject to the same punishments, or, in the words of Rule 25 of the Ancyra Council, “those guilty of guilt.” The doctrine of complicity (σύμπραζις) in a crime was developed in Roman law, and this doctrine is expressed in this rule. An accomplice, in a general sense, is anyone who knowingly aids and assists the principal culprit in the commission of a criminal offense. Complicity can be of two types: direct, when a known person approves and actively helps the criminal to carry out his criminal intention, and indirect or intellectual, when someone knowingly incites a known person to commit a criminal offense. Complicity also includes when someone assists a criminal with acts that are in connection with a criminal matter with the aim of making it easier to commit, concealing it, or releasing the criminal from punishment. Those who hide one or another culprit of a crime and do not report this to the authorities in order to hide the culprit from punishment are also guilty of complicity 109 . See about this in my op. "Tsrkveno executed right", pp. 84–88 and 454. You might be interested in:
