1 Objection 1: It would seem that one miracle is not greater than another. For Augustine says Epist. ad Volusian. cxxxvii): In miraculous deeds, the whole measure of the deed is the power of the doer. But by the same power of God all miracles are done. Therefore one miracle is not greater than another.
1 Ad octavum sic proceditur. Videtur quod unum miraculum non sit maius alio. Dicit enim Augustinus, in epistola ad Volusianum, in rebus mirabiliter factis tota ratio facti est potentia facientis. Sed eadem potentia, scilicet Dei, fiunt omnia miracula. Ergo unum non est maius alio.
2 Objection 2: Further, the power of God is infinite. But the infinite exceeds the finite beyond all proportion; and therefore no more reason exists to wonder at one effect thereof than at another. Therefore one miracle is not greater than another.
2 Praeterea, potentia Dei est infinita. Sed infinitum improportionabiliter excedit omne finitum. Ergo non magis est mirandum quod faciat hunc effectum, quam illum. Ergo unum miraculum non est maius altero.
3 On the contrary, The Lord says, speaking of miraculous works Jn. 14, 12): The works that I do, he also shall do, and greater than these shall he do.
3 Sed contra est quod dominus dicit, Ioan. XIV, de operibus miraculosis loquens, opera quae ego facio, et ipse faciet, et maiora horum faciet.
4 I answer that, Nothing is called a miracle by comparison with the Divine Power; because no action is of any account compared with the power of God, according to Is. 40, 15: Behold the Gentiles are as a drop from a bucket, and are counted as the smallest grain of a balance. But a thing is called a miracle by comparison with the power of nature which it surpasses. So the more the power of nature is surpassed, the greater the miracle.
Now the power of nature is surpassed in three ways: firstly, in the substance of the deed, for instance, if two bodies occupy the same place, or if the sun goes backwards; or if a human body is glorified: such things nature is absolutely unable to do; and these hold the highest rank among miracles. Secondly, a thing surpasses the power of nature, not in the deed, but in that wherein it is done; as the raising of the dead, and giving sight to the blind, and the like; for nature can give life, but not to the dead; and such hold the second rank in miracles.
Thirdly, a thing surpasses nature's power in the measure and order in which it is done; as when a man is cured of a fever suddenly, without treatment or the usual process of nature; or as when the air is suddenly condensed into rain, by Divine power without a natural cause, as occurred at the prayers of Samuel and Elias; and these hold the lowest place in miracles. Moreover, each of these kinds has various degrees, according to the different ways in which the power of nature is surpassed. From this is clear how to reply to the objections, arguing as they do from the Divine power.
4 Respondeo dicendum quod nihil potest dici miraculum ex comparatione potentiae divinae, quia quodcumque factum, divinae potentiae comparatum, est minimum; secundum illud Isaiae XL, ecce gentes quasi stilla situlae, et quasi momentum staterae reputatae sunt. Sed dicitur aliquid miraculum per comparationem ad facultatem naturae, quam excedit. Et ideo secundum quod magis excedit facultatem naturae, secundum hoc maius miraculum dicitur. Excedit autem aliquid facultatem naturae tripliciter. Uno modo, quantum ad substantiam facti, sicut quod duo corpora sint simul, vel quod sol retrocedat, aut quod corpus humanum glorificetur; quod nullo modo natura facere potest. Et ista tenent summum gradum in miraculis. Secundo aliquid excedit facultatem naturae, non quantum ad id quod fit, sed quantum ad id in quo fit, sicut resuscitatio mortuorum, et illuminatio caecorum, et similia. Potest enim natura causare vitam, sed non in mortuo, et potest praestare visum, sed non caeco. Et haec tenent secundum locum in miraculis. Tertio modo excedit aliquid facultatem naturae, quantum ad modum et ordinem faciendi, sicut cum aliquis subito per virtutem divinam a febre curatur absque curatione et consueto processu naturae in talibus, et cum statim aer divina virtute in pluvias densatur absque naturalibus causis, sicut factum est ad preces Samuelis et Eliae. Et huiusmodi tenent infimum locum in miraculis. Quaelibet tamen horum habent diversos gradus, secundum quod diversimode excedunt facultatem naturae. Et per hoc patet solutio ad obiecta, quae procedunt ex parte divinae potentiae.
