Marcion Rejected the Preceding Portion of St. Luke's Gospel. Therefore This Review Opens with an Examination of the Case of the Evil Spirit in the Synagogue of Capernaum. He Whom the Demon Acknowledged Was the Creator's Christ
My present discussion is, how the evil spirit could have known that He was called by such a name, when there had never at any time been uttered about Him a single prophecy by a god who was unknown, and up to that time silent, of whom it was not possible for Him to be attested as “the Holy One,” as (of a god) unknown even to his own Creator. What similar event could he then have published of a new deity, whereby he might betoken for “the holy one” of the rival god?
Simply that he went into the synagogue, and did nothing even in word against the Creator? As therefore he could not by any means acknowledge him, whom he was ignorant of, to be Jesus and the Holy One of God; so did he acknowledge Him whom he knew (to be both). For he remembered how that the prophet had prophesied of “the Holy One” of God, and how that God's name of “Jesus” was in the son of Nun. These facts he had also received from the angel, according to our Gospel: “Wherefore that which shall be born of you shall be called the Holy One, the Son of God;” and, “You shall call his name Jesus.” Thus he actually had (although only an evil spirit) some idea of the Lord's dispensation, rather than of any strange and heretofore imperfectly understood one.
Because he also premised this question: “What have we to do with You?”— not as if referring to a strange Jesus, to whom pertain the evil spirits of the Creator. Nor did he say, What have You to do with us? But, “What have we to do with You?” as if deploring himself, and deprecating his own calamity; at the prospect of which he adds: “Have You come to destroy us?” So completely did he acknowledge in Jesus the Son of that God who was judicial and avenging, and (so to speak) severe, and not of him who was simply good, and knew not how to destroy or how to punish!
Now for what purpose have we adduced his passage first? In order to show that Jesus was neither acknowledged by the evil spirit, nor affirmed by Himself, to be any other than the Creator's. Well, but Jesus rebuked him, you say. To be sure he did, as being an envious (spirit), and in his very confession only petulant, and evil in adulation— just as if it had been Christ's highest glory to have come for the destruction of demons, and not for the salvation of mankind; whereas His wish really was that His disciples should not glory in the subjection of evil spirits but in the fair beauty of salvation. Why else did He rebuke him?
If it was because he was entirely wrong (in his invocation), then He was neither Jesus nor the Holy One of God; if it was because he was partially wrong— for having supposed him to be, rightly enough, Jesus and the Holy One of God, but also as belonging to the Creator— most unjustly would He have rebuked him for thinking what he knew he ought to think (about Him), and for not supposing that of Him which he knew not that he ought to suppose— that he was another Jesus, and the holy one of the other god.
If, however, the rebuke has not a more probable meaning than that which we ascribe to it, it follows that the evil spirit made no mistake, and was not rebuked for lying; for it was Jesus Himself, besides whom it was impossible for the evil spirit to have acknowledged any other, while Jesus affirmed that He was He whom the evil spirit had acknowledged, by not rebuking him for uttering a lie.
