But some most worthless persons are in the habit of carrying about the name [of Jesus Christ] in wicked guile, while yet they practise things unworthy of God, and hold opinions contrary to the doctrine of Christ, to their own destruction, and that of those who give credit to them, whom you must avoid as ye would wild beasts. For “the righteous man who avoids them is saved for ever; but the destruction of the ungodly is sudden, and a subject of rejoicing.”[792] For “they are dumb dogs, that cannot bark,”[793] raving mad, and biting secretly, against whom ye must be on your guard, since they labour under an incurable disease. But our Physician is the only true God, the unbegotten and unapproachable, the Lord of all, the Father and Begetter of the only-begotten Son. We have also as a Physician the Lord our God, Jesus the Christ, the only-begotten Son and Word, before time began,[794] but who afterwards became also man, of Mary the virgin. For “the Word was made flesh.”[795] Being incorporeal, He was in the body; being impassible, He was in a passible body; being immortal, He was in a mortal body; being life, He became subject to corruption, that He might free our souls from death and corruption, and heal them, and might restore them to health, when they were diseased with ungodliness and wicked lusts. CHAP. VIII.—_Renewed praise of the Ephesians._ SHORTER. Let not then any one deceive you, as indeed ye are not deceived, inasmuch as ye are wholly devoted to God. For since there is no strife raging among you which might distress you, ye are certainly living in accordance with God’s will. I am far inferior to you, and require to be sanctified by your church of Ephesus, so renowned throughout the world. They that are carnal cannot do those things which are spiritual, nor they that are spiritual the things which are carnal; even as faith cannot do the works of unbelief, nor unbelief the works of faith. But even those things which ye do according to the flesh are spiritual; for ye do all things in Jesus Christ. LONGER. Let not then any one deceive you, as indeed ye are not deceived; for ye are wholly devoted to God. For when there is no evil desire within you, which might defile and torment you, then do ye live in accordance with the will of God, and are [the servants] of Christ. Cast ye out that which defiles[796] you, who are of the[797] most holy church of the Ephesians, which is so famous and celebrated throughout the world. They that are carnal cannot do those things which are spiritual, nor they that are spiritual the things which are carnal; even as faith cannot do the works of unbelief, nor unbelief the works of faith. But ye, being full of the Holy Spirit, do nothing according to the flesh, but all things according to the Spirit. Ye are complete in Christ Jesus, “who is the Saviour of all men, specially of them that believe.”[798] CHAP. IX.—_Ye have given no heed to false teachers._ SHORTER.
