Catechesis: Monastic Vows

However, very clearly the monks have taught that their humanly invented observances make satisfaction for sins and merit grace and justification. What is this but to detract from the glory of Christ and to obscure and deny the righteousness of faith? If follows, therefore, that such customary vows were ungodly acts of worship and are invalid for that reason.—AC XXVII:38, 39.
