But you, dearly beloved, whom I address in no less earnest terms than those of the blessed Apostle Peter, “a chosen race, a royal priesthood, a holy nation, a people for God’s own possession,” built upon the impregnable rock, Christ, and joined to the Lord our Saviour by His true assumption of our flesh, remain firm in that Faith, which you have professed before many witnesses, and in which you were reborn through water and the Holy Ghost, and received the anointing of salvation, and the seal of eternal life. But “if any one preach to you any thing beside that which you have learnt, let him be anathema:” refuse to put wicked fables before the clearest truth, and what you may happen to read or hear contrary to the rule of the catholic and Apostolic creed, judge it altogether deadly and diabolical. Be not carried away by their deceitful keepings of sham and pretended fasts which tend not to the cleansing, but to the destroying of men’s souls. They put on indeed a cloke of piety and chastity, but under this deceit they conceal the filthiness of their acts, and from the recesses of their ungodly heart hurl shafts to wound the simple; that, as the prophet says, “they may shoot in darkness at the upright in heart.” A mighty bulwark is a sound faith, a true faith, to which nothing has to be added or taken away: because unless it is one, it is no faith, as the Apostle says, “one Lord, one faith, one baptism, one God and Father of all, who is above all, and through all, and in us all.” Cling to this unity, dearly beloved, with minds unshaken, and in it “follow after” all “holiness,” in it carry out the Lord’s commands, because “without faith it is impossible to please God,” and without it nothing is holy, nothing is pure, nothing alive: “for the just lives by faith,” and he who by the devil’s deception loses it, is dead though living, because as righteousness is gained by faith, so too by a true faith is eternal life gained, as says our Lord and Saviour. And this is life eternal, that they may know Thee, the only true God, and Jesus Christ, whom Thou hast sent. May He make you to advance and persevere to the end, Who lives and reigns with the Father and the Holy Spirit, for ever and ever. Amen.
