Against Heresies: Book III
5. They were confounded, therefore, both by this instance of healing (“for the man was above forty years old on whom this miracle of healing took place”), and by the doctrine of the apostles, and by the exposition of the prophets, when the chief priests had sent away Peter and John. [These latter] returned to the rest of their fellow-apostles and disciples of the Lord, that is, to the Church, and related what had occurred, and how courageously they had acted in the name of Jesus. The whole Church, it is then said, “when they had heard that, lifted up the voice to God with one accord, and said, Lord, Thou art God, which hast made heaven, and earth, and the sea, and all that in them is; who, through the Holy Ghost, by the mouth of our father David, Thy servant, hast said, Why did the heathen rage, and the people imagine vain things? The kings of the earth stood up, and the rulers were gathered together against the Lord, and against His Christ. For of a truth, in this city, against Thy holy Son Jesus, whom Thou hast anointed, both Herod and Pontius Pilate, with the Gentiles, and the people of Israel, were gathered together, to do whatsoever Thy hand and Thy counsel determined before to be done.” These [are the] voices of the Church from which every Church had its origin; these are the voices of the metropolis of the citizens of the new covenant; these are the voices of the apostles; these are voices of the disciples of the Lord, the truly perfect, who, after the assumption of the Lord, were perfected by the Spirit, and called upon the God who made heaven, and earth, and the sea,—who was announced by the prophets,— and Jesus Christ His Son, whom God anointed, and who knew no other [God]. For at that time and place there was neither Valentinus, nor Marcion, nor the rest of these subverters [of the truth], and their adherents. Wherefore God, the Maker of all things, heard them. For it is said, “The place was shaken where they were assembled together; and they were all filled with the Holy Ghost, and they spake the word of God with boldness” to every one that was willing to believe.
“And with great power,” it is added, “gave the apostles witness of the resurrection of the Lord Jesus,” saying to them, “The God of our fathers raised up Jesus, whom ye seized and slew, hanging [Him] upon a beam of wood: Him hath God raised up by His right hand to be a Prince and Saviour, to give repentance to Israel, and forgiveness of sins. And we are in this witnesses of these words; as also is the Holy Ghost, whom God hath given to them that believe in Him.” “And daily,” it is said, “in the temple, and from house to house, they ceased not to teach and preach Christ Jesus,” the Son of God. For this was the knowledge of salvation, which renders those who acknowledge His Son’s advent perfect towards God.
6. But as some of these men impudently assert that the apostles, when preaching among the Jews, could not declare to them another god besides Him in whom they (their hearers) believed, we say to them, that if the apostles used to speak to people in accordance with the opinion instilled into them of old, no one learned the truth from them, nor, at a much earlier date, from the Lord; for they say that He did Himself speak after the same fashion. Wherefore neither do these men themselves know the truth; but since such was their opinion regarding God, they had just received doctrine as they were able to hear it. According to this manner of speaking, therefore, the rule of truth can be with nobody; but all learners will ascribe this practice to all [teachers], that just as every person thought, and as far as his capability extended, so was also the language addressed to him. But the advent of the Lord will appear superfluous and useless, if He did indeed come intending to tolerate and to preserve each man’s idea regarding God rooted in him from of old. Besides this, also, it was a much heavier task, that He whom the Jews had seen as a man, and had fastened to the cross, should be preached as Christ the Son of God, their eternal King. Since this, however, was so, they certainly did not speak to them in accordance with their old belief. For they, who told them to their face that they were the slayers of the Lord, would themselves also much more boldly preach that Father who is above the Demiurge, and not what each individual bid himself believe [respecting God]; and the sin was much less, if indeed they had not fastened to the cross the superior Saviour (to whom it behoved them to ascend), since He was impassible. For, as they did not speak to the Gentiles in compliance with their notions, but told them with boldness that their gods were no gods, but the idols of demons; so would they in like manner have preached to the Jews, if they had known another greater or more perfect Father, not nourishing nor strengthening the untrue opinion of these men regarding God. Moreover, while destroying the error of the Gentiles, and bearing them away from their gods, they did not certainly induce another error upon them; but, removing those which were no gods, they pointed out Him who alone was God and the true Father.
7. From the words of Peter, therefore, which he addressed in Cæsarea to Cornelius the centurion, and those Gentiles with him, to whom the word of God was first preached, we can understand what the apostles used to preach, the nature of their preaching, and their idea with regard to God. For this Cornelius was, it is said, “a devout man, and one who feared God with all his house, giving much alms to the people, and praying to God always. He saw therefore, about the ninth hour of the day, an angel of God coming in to him, and saying, Thine alms are come up for a memorial before God. Wherefore send to Simon, who is called Peter.” But when Peter saw the vision, in which the voice from heaven said to him, “What God hath cleansed, that call not thou common,” this happened [to teach him] that the God who had, through the law, distinguished between clean and unclean, was He who had purified the Gentiles through the blood of His Son—He whom also Cornelius worshipped; to whom Peter, coming in, said, “Of a truth I perceive that God is no respecter of persons: but in every nation, he that feareth Him, and worketh righteousness, is acceptable to Him.” He thus clearly indicates, that He whom Cornelius had previously feared as God, of whom he had heard through the law and the prophets, for whose sake also he used to give alms, is, in truth, God. The knowledge of the Son was, however, wanting to him; therefore did [Peter] add, “The word, ye know, which was published throughout all Judea, beginning from Galilee, after the baptism which John preached, Jesus of Nazareth, how God anointed Him with the Holy Ghost, and with power; who went about doing good, and healing all that were oppressed of the devil; for God was with Him. And we are witnesses of all those things which He did both in the land of the Jews and in Jerusalem; whom they slew, hanging Him on a beam of wood: Him God raised up the third day, and showed Him openly; not to all the people, but unto us, witnesses chosen before of God, who did eat and drink with Him after the resurrection from the dead. And He commanded us to preach unto the people, and to testify that it is He which was ordained of God to be the Judge of quick and dead. To Him give all the prophets witness, that, through His name, every one that believeth in Him does receive remission of sins.”
The apostles, therefore, did preach the Son of God, of whom men were ignorant; and His advent, to those who had been already instructed as to God; but they did not bring in another god. For if Peter had known any such thing, he would have preached freely to the Gentiles, that the God of the Jews was indeed one, but the God of the Christians another; and all of them, doubtless, being awe-struck because of the vision of the angel, would have believed whatever he told them. But it is evident from Peter’s words that he did indeed still retain the God who was already known to them; but he also bare witness to them that Jesus Christ was the Son of God, the Judge of quick and dead, into whom he did also command them to be baptized for the remission of sins; and not this alone, but he witnessed that Jesus was Himself the Son of God, who also, having been anointed with the Holy Spirit, is called Jesus Christ. And He is the same being that was born of Mary, as the testimony of Peter implies. Can it really be, that Peter was not at that time as yet in possession of the perfect knowledge which these men discovered afterwards? According to them, therefore, Peter was imperfect, and the rest of the apostles were imperfect; and so it would be fitting that they, coming to life again, should become disciples of these men, in order that they too might be made perfect. But this is truly ridiculous. These men, in fact, are proved to be not disciples of the apostles, but of their own wicked notions. To this cause also are due the various opinions which exist among them, inasmuch as each one adopted error just as he was capable [of embracing it]. But the Church throughout all the world, having its origin firm from the apostles, perseveres in one and the same opinion with regard to God and His Son.
