Translated from the Greek
5 And what are we to say regarding the prophecies of Christ in the Psalms, there being a certain ode with the superscription “For the Beloved,” whose tongue is said to be the “pen of a ready writer, who is fairer than the sons of men,” since “grace was poured on His lips?” For a proof that grace was poured on His lips is this, that although the period of His teaching was short— for He taught somewhere about a year and a few months— the world has been filled with his teaching, and with the worship of God (established) through Him. For there arose “in His days righteousness and abundance of peace,” which abides until the consummation, which has been called the taking away of the moon; and He continues “ruling from sea to sea, and from the rivers to the ends of the earth.” And to the house of David has been given a sign: for the Virgin bore, and was pregnant, and brought forth a son, and His name is Emmanuel, which is, “God with us;” and as the same prophet says, the prediction has been fulfilled, “God (is) with us; know it, O nations, and be overcome; you who are strong, be vanquished:” for we of the heathen have been overcome and vanquished, we who have been taken by the grace of His teaching. The place also of His birth has been foretold in (the prophecies of) Micah: “For you, Bethlehem,” he says, “land of Judah, art by no means the least among the rulers of Judah; for out of you shall come forth a Ruler, who shall rule My people Israel.” And according to Daniel, seventy weeks were fulfilled until (the coming of) Christ the Ruler. And He came, who, according to Job, has subdued the great fish, and has given power to His true disciples to tread upon serpents and scorpions, and all the power of the enemy, without sustaining any injury from them. And let one notice also the universal advent of the apostles sent by Jesus to announce the Gospel, and he will see both that the undertaking was beyond human power, and that the commandment came from God. And if we examine how men, on hearing new doctrines, and strange words, yielded themselves up to these teachers, being overcome, amid the very desire to plot against them, by a divine power that watched over these (teachers), we shall not be incredulous as to whether they also wrought miracles, God bearing witness to their words both by signs, and wonders, and various miracles.
6. And while we thus briefly demonstrate the deity of Christ, and (in so doing) make use of the prophetic declarations regarding Him, we demonstrate at the same time that the writings which prophesied of Him were divinely inspired; and that those documents which announced His coming and His doctrine were given forth with all power and authority, and that on this account they obtained the election from the Gentiles. We must say, also, that the divinity of the prophetic declarations, and the spiritual nature of the law of Moses, shone forth after the advent of Christ. For before the advent of Christ it was not altogether possible to exhibit manifest proofs of the divine inspiration of the ancient Scripture; whereas His coming led those who might suspect the law and the prophets not to be divine, to the clear conviction that they were composed by (the aid of) heavenly grace. And he who reads the words of the prophets with care and attention, feeling by the very perusal the traces of the divinity that is in them, will be led by his own emotions to believe that those words which have been deemed to be the words of God are not the compositions of men. The light, moreover, which was contained in the law of Moses, but which had been concealed by a veil, shone forth at the advent of Jesus, the veil being taken away, and those blessings, the shadow of which was contained in the letter, coming forth gradually to the knowledge (of men).
7. It would be tedious now to enumerate the most ancient prophecies respecting each future event, in order that the doubter, being impressed by their divinity, may lay aside all hesitation and distraction, and devote himself with his whole soul to the words of God. But if in every part of the Scriptures the superhuman element of thought does not seem to present itself to the uninstructed, that is not at all wonderful for, with respect to the works of that providence which embraces the whole world, some show with the utmost clearness that they are works of providence, while others are so concealed as to seem to furnish ground for unbelief with respect to that God who orders all things with unspeakable skill and power. For the artistic plan of a providential Ruler is not so evident in those matters belonging to the earth, as in the case of the sun, and moon, and stars; and not so clear in what relates to human occurrences, as it is in the souls and bodies of animals,— the object and reason of the impulses, and phantasies and natures of animals, and the structure of their bodies, being carefully ascertained by those who attend to these things. But as (the doctrine of) providence is not at all weakened (on account of those things which are not understood) in the eyes of those who have once honestly accepted it, so neither is the divinity of Scripture, which extends to the whole of it, (lost) on account of the inability of our weakness to discover in every expression the hidden splendour of the doctrines veiled in common and unattractive phraseology. For we have the treasure in earthen vessels, that the excellency of the power of God may shine forth, and that it may not be deemed to proceed from us (who are but) human beings. For if the hackneyed methods of demonstration (common) among men, contained in the books (of the Bible), had been successful in producing conviction; then our faith would rightly have been supposed to rest on the wisdom of men, and not on the power of God; but now it is manifest to everyone who lifts up his eyes, that the word and preaching have not prevailed among the multitude “by persuasive words of wisdom, but by demonstration of the Spirit and of power.” Wherefore, since a celestial or even a super-celestial power compels us to worship the only Creator, let us leave the doctrine of the beginning of Christ, i.e., the elements, and endeavour to go on to perfection, in order that the wisdom spoken to the perfect may be spoken to us also. For he who possesses it promises to speak wisdom among them that are perfect, but another wisdom than that of this world, and of the rulers of this world, which is brought to nought. And this wisdom will be distinctly stamped upon us, and will produce a revelation of the mystery that was kept silent in the eternal ages, but now has been manifested through the prophetic Scriptures, and the appearance of our Lord and Saviour Jesus Christ, to whom be glory for ever and ever. Amen.
