Chapter 1.—What the Author Entreats from God, What from the Reader. In God Nothing is to Be Thought Corporeal or Changeable.

1. Beginning, as I now do henceforward, to speak of subjects which cannot altogether be spoken as they are thought, either by any man, or, at any rate, not by myself; although even our very thought, when we think of God the Trinity, falls (as we feel) very far short of Him of whom we think, nor comprehends Him as He is; but He is seen, as it is written, even by those who are so great as was the Apostle Paul, “through a glass and in an enigma:”557    [The original is: “ut sit participatio ejus in idipsum.” The English translator renders: “So that it may partake thereof in itself.” The thought of Augustin is, that the believing soul though mutable partakes of the immutable; and he designates the immutable as the in idipsum: the self-existent. In that striking passage in the Confessions, in which he describes the spiritual and extatic meditations of himself and his mother, as they looked out upon the Mediterranean from the windows at Ostia—a scene well known from Ary Schefer’s painting—he denominates God the idipsum: the “self same” (Confessions IX. x). Augustin refers to the same absolute immutability of God, in this place. By faith, man is “a partaker of a divine nature,” (2 Pet. i. 4.)—W.G.T.S.]    Ps. lxviii. 9.—Pluviam voluntariam.    1 Cor. xiii. 12 first, I pray to our Lord God Himself, of whom we ought always to think, and of whom we are not able to think worthily, in praise of whom blessing is at all times to be rendered,558    Ps. cxxii. 3. Vulg.    Gratis.    Ps. xxxiv. 1 and whom no speech is sufficient to declare, that He will grant me both help for understanding and explaining that which I design, and pardon if in anything I offend. For I bear in mind, not only my desire, but also my infirmity. I ask also of my readers to pardon me, where they may perceive me to have had the desire rather than the power to speak, what they either understand better themselves, or fail to understand through the obscurity of my language, just as I myself pardon them what they cannot understand through their own dullness.

2. And we shall mutually pardon one another the more easily, if we know, or at any rate firmly believe and hold, that whatever is said of a nature, unchangeable, invisible and having life absolutely and sufficient to itself, must not be measured after the custom of things visible, and changeable, and mortal, or not self-sufficient. But although we labor, and yet fail, to grasp and know even those things which are within the scope of our corporeal senses, or what we are ourselves in the inner man; yet it is with no shamelessness that faithful piety burns after those divine and unspeakable things which are above: piety, I say, not inflated by the arrogance of its own power, but inflamed by the grace of its Creator and Saviour Himself. For with what understanding can man apprehend God, who does not yet apprehend that very understanding itself of his own, by which he desires to apprehend Him? And if he does already apprehend this, let him carefully consider that there is nothing in his own nature better than it; and let him see whether he can there see any outlines of forms, or brightness of colors, or greatness of space, or distance of parts, or extension of size, or any movements through intervals of place, or any such thing at all. Certainly we find nothing of all this in that, than which we find nothing better in our own nature, that is, in our own intellect, by which we apprehend wisdom according to our capacity. What, therefore, we do not find in that which is our own best, we ought not to seek in Him who is far better than that best of ours; that so we may understand God, if we are able, and as much as we are able, as good without quality, great without quantity, a creator though He lack nothing, ruling but from no position, sustaining all things without “having” them, in His wholeness everywhere, yet without place, eternal without time, making things that are changeable, without change of Himself, and without passion. Whoso thus thinks of God, although he cannot yet find out in all ways what He is, yet piously takes heed, as much as he is able, to think nothing of Him that He is not.

CAPUT PRIMUM.

1. Quid a Deo, quid a lectore auctor exposcat. In Deo nihil mutabilis et corporei cogitandum. Hinc jam exordiens ea dicere, quae dici ut cogitantur vel ab homine aliquo, vel certe a nobis non omni modo possunt: quamvis et ipsa nostra cogitatio, cum de Deo Trinitate cogitamus , longe se illi de quo cogitat, imparem sentiat, neque ut est eum capiat, sed, ut scriptum est, etiam a tantis quantus Paulus apostolus hic erat, per speculum et in aenigmate videatur (I Cor. XIII, 12), primum ab ipso Domino Deo nostro, de quo semper cogitare debemus, et de quo digne cogitare non possumus, cui laudando reddenda est omni tempore benedictio (Psal. XXXIII, 1), et cui enuntiando nulla competit dictio, et adjutorium ad intelligenda atque explicanda quae intendo, et veniam precor sicubi offendo. Memor sum enim, non solum voluntatis, verum etiam infirmitatis meae. Ab his etiam qui ista lecturi sunt, ut ignoscant peto, ubi me magis voluisse quam potuisse dicere adverterint, quod vel ipsi melius intelligunt, vel propter mei eloquii difficultatem non intelligunt: sicut ego eis ignosco, ubi propter suam tarditatem intelligere non possunt.

2. Facilius autem nobis invicem ignoscimus, si noverimus, aut certe credendo firmum tenuerimus, ea quae de natura incommutabili et invisibili summeque vivente ac sibi sufficiente dicuntur, non ex consuetudine visibilium atque mutabilium et mortalium vel egenarum rerum esse metienda. Sed cum in his etiam quae nostris corporalibus adjacent sensibus, vel quod nos ipsi in interiore homine sumus, scientia comprehendendis laboremus, nec sufficiamus: non tamen impudenter in illa quae supra sunt divina et ineffabilia, pietas fidelis ardescit; non quam suarum virium inflat arrogantia, sed quam gratia ipsius Creatoris et Salvatoris inflammat. Nam quo intellectu Deum capit homo, qui ipsum intellectum suum quo eum vult capere nondum capit? Si autem hunc jam capit, attendat diligenter nihil eo esse in sua natura melius, 0912 et videat utrum ibi videat ulla lineamenta formarum, nitores colorum, spatiosam granditatem, partium distantiam, molis distensionem, aliquas per locorum intervalla motiones, vel quid ejusmodi. Nihil certe istorum invenimus in eo, quo in natura nostra nihil melius invenimus, id est, in nostro intellectu, quo sapientiam capimus quantum capaces sumus. Quod ergo non invenimus in meliore nostro, non debemus in illo quaerere, quod longe melius est meliore nostro: ut sic intelligamus Deum, si possumus, quantum possumus, sine qualitate bonum, sine quantitate magnum, sine indigentia creatorem, sine situ praesidentem , sine habitu omnia continentem, sine loco ubique totum, sine tempore sempiternum, sine ulla sui mutatione mutabilia facientem, nihilque patientem. Quisquis Deum ita cogitat, etsi nondum potest omni modo invenire quid sit; pie tamen cavet, quantum potest, aliquid de eo sentire quod non sit.
