John 8:35

He alone can free from sin, who came without sin, and was made a sacrifice for sin. And thus it follows: The servant abideth not in the house for ever. The Church is the house: the servant is the sinner; and many sinners enter into the Church. So He does not say, The servant is, not in the house; but, The servant abideth not in the house for ever. If a time then is to come, when there shall be no servant in the house; who will there be there? Who will boast that he is pure from sin? Christ's are fearful words. But He adds, The Son abideth for ever. So then Christ will live alone in His house. Or does not the word Son, imply both the body and the head? Christ purposely alarms us first, and then gives us hope. He alarms us, that we may not love sin; He gives us hope, that we may not despair of the absolution of our sin.

"The servant abideth not in the house, but the Son abideth forever." Gently too from this He casts down the things of the Law, alluding to former times. For that they may not run back to them and say, "We have the sacrifices which Moses commanded, they are able to deliver us," He addeth these words, since otherwise what connection would the saying have? For "all have sinned, and come short of the glory of God, being justified freely by His grace," even the priests themselves. Wherefore Paul also saith of the priest, that "he ought as for the people so also for himself to offer for sins, for that he also is compassed about with infirmity." And this is signified by His saying, "The servant abideth not in the house." Here also He showeth His equal honor with the Father, and the difference between slave and free. For the parable has this meaning, that is, "the servant hath no power," this is the meaning of "abideth not."

"And the servant abideth not in the house for ever." The church is the house, the servant is the sinner. Many sinners enter the church. Accordingly He has not said, "The servant" is not in the house, but "abideth not in the house for ever." If, then, there shall be no servant there, who will be there? For "when" as the Scripture speaketh, "the righteous king sitteth on the throne, who will boast of having a clean heart? or who will boast that he is pure from his sin?" He has greatly alarmed us, my brethren, by saying, "The servant abideth not in the house for ever." But He further adds, "But the Son abideth ever." Will Christ, then, be alone in His house? Will no people remain at His side? Whose head will He be, if there shall be no body? Or is the Son all this, both the head and the body? For it is not without cause that He has inspired both terror and hope: terror, in order that we should not love sin; and hope, that we should not be distrustful of the remission of sin. "Every one," He says, "that committeth sin is the servant of sin. And the servant abideth not in the house for ever."
