Lactantius — Divine Institutes 4.15
Having spoken of the second nativity, in which, He showed Himself in the flesh to men , let us come to those wonderful works , on account of which, though they were signs of heavenly power, the Jews esteemed Him a magician. When He first began to reach maturity He was baptized by the prophet John in the river Jordan, that He might wash away in the spiritual laver not His own sins , for it is evident that He had none, but those of the flesh, which He bare; that as He saved the Jews by undergoing circumcision , so He might save the Gentiles also by baptism — that is, by the pouring forth of the purifying dew. Then a voice from heaven was heard: You are my Son, today have I begotten You. Which voice is found to have been foretold by David. And the Spirit of God descended upon Him, formed after the appearance of a white dove.
From that time He began to perform the greatest miracles , not by magical tricks, which display nothing true and substantial, but by heavenly strength and power, which were foretold even long ago by the prophets who announced Him; which works are so many, that a single book is not sufficient to comprise them all. I will therefore enumerate them briefly and generally, without any designation of persons and places, that I may be able to come to the setting forth of His passion and cross, to which my discourse has long been hastening.
His powers were those which Apollo called wonderful: that wherever He journeyed, by a single word, and in a single moment, He healed the sick and infirm, and those afflicted with every kind of disease: so that those who were deprived of the use of all their limbs, having suddenly received power, were strengthened, and themselves carried their couches, on which they had a little time before been carried. But to the lame, and to those afflicted with some defect of the feet, He not only gave the power of walking, but also of running. Then, also, if any had their eyes blinded in the deepest darkness, He restored them to their former sight. He also loosened the tongues of the dumb, so that they discoursed and spoke eloquently. He also opened the ears of the deaf, and caused them to hear; He cleansed the polluted and the blemished.
And He performed all these things not by His hands, or the application of any remedy, but by His word and command, as also the Sibyl had foretold: Doing all things by His word, and healing every disease. Nor, indeed, is it wonderful that He did wonderful things by His word, since He Himself was the Word of God , relying upon heavenly strength and power. Nor was it enough that He gave strength to the feeble, soundness of body to the maimed, health to the sick and languishing, unless He also raised the dead, as it were unbound from sleep, and recalled them to life. And the Jews , then, when they saw these things, contended that they were done by demoniacal power, although it was contained in their secret writings that all things should thus come to pass as they did.
