Thomas Aquinas

“ From all these instances it is clear that Christ, when He willed, changed the minds of men by His Divine power, not only by the bestowal of righteousness and the infusion of wisdom, which pertains to the end of miracles, but also by outwardly drawing men to Himself, or by terrifying or stupefying them, which pertains to the miraculous itself. ”

“ Now Christ came into the world and taught in order to save man, according to Jn. 3:17: "For God sent not His Son into the world to judge the world, but that the world may be saved by Him." Therefore it was fitting that Christ, by miraculously healing men in particular, should prove Himself to be the universal and spiritual Saviour of all. ”

“ Christ came to save the world, not only by Divine power, but also through the mystery of His Incarnation. Consequently in healing the sick He frequently not only made use of His Divine power, healing by way of command, but also by applying something pertaining to His human nature. ”

“ The third miracle was that the eclipse of the sun naturally always begins in that part of the sun which is to the west and spreads towards the east: and this is because the moon's proper movement from west to east is more rapid than that of the sun, and consequently the moon, coming up from the west, overtakes the sun and passes it on its eastward course. ”

“ We are hereby given to understand that ailments of the body are frequently due to sin: for which reason, perhaps, first are his sins forgiven, that the cause of the ailment being removed, health may return. ”

“ Further, it was more fitting that Christ should work miracles in life and when teaching, than in death: both because, as it is written (2 Cor. 13:4) , "He was crucified through weakness, yet He liveth by the power of God," by which He worked miracles; and because His miracles were in confirmation of His doctrine. But there is no record of Christ having worked any miracles in the heavenly bodies during His lifetime: nay, more; when the Pharisees asked Him to give "a sign from heaven," He refused, as Matthew relates (12,16) . ”

“ The miracles which Christ worked in expelling demons were for the benefit, not of the demons, but of men, that they might glorify Him. Wherefore He forbade them to speak in His praise. First, to give us an example. For, as Athanasius says, "He restrained his speech, although he was confessing the truth; to teach us not to care about such things, although it may seem that what is said is true. For it is wrong to seek to learn from the devil when we have the Divine Scripture": Besides, it is dangerous, since the demons frequently mix falsehood with truth. ”

“ And this, in so far as the enlightenment was inward, is not to be reckoned as a miracle, but only as regards the outward action---namely, in so far as men saw that those who had been unlettered and simple spoke with such wisdom and constancy. ”
