On the Trinity

But it is by love that we must stand firm to this and cleave to this, in order that we may enjoy the presence of that by which we are, and in the absence of which we could not be at all. For as “we walk as yet by faith, and not by sight,” we certainly do not yet see God, as the same [apostle] saith, “face to face:” whom however we shall never see, unless now already we love. But who loves what he does not know? For it is possible something may be known and not loved: but I ask whether it is possible that what is not known can be loved; since if it cannot, then no one loves God before he knows Him. And what is it to know God except to behold Him and steadfastly perceive Him with the mind? For He is not a body to be searched out by carnal eyes. But before also that we have power to behold and to perceive God, as He can be beheld and perceived, which is permitted to the pure in heart; for “blessed are the pure in heart. for they shall see God;” except He is loved by faith, it will not be possible for the heart to be cleansed, in order that it may be apt and meet to see Him. For where are there those three, in order to build up which in the mind the whole apparatus of the divine Scriptures has been raised up, namely Faith, Hope, and Charity, except in a mind believing what it does not yet see, and hoping and loving what it believes? Even He therefore who is not known, but yet is believed, can be loved. But indisputably we must take care, lest the mind believing that which it does not see, feign to itself something which is not, and hope for and love that which is false. For in that case, it will not be charity out of a pure heart, and of a good conscience, and of faith unfeigned, which is the end of the commandment, as the same apostle says.

But it must needs be, that, when by reading or hearing of them we believe in any corporeal things which we have not seen, the mind frames for itself something under bodily features and forms, just as it may occur to our thoughts; which either is not true, or even if it be true, which can most rarely happen, yet this is of no benefit to us to believe in by faith, but it is useful for some other purpose, which is intimated by means of it. For who is there that reads or hears what the Apostle Paul has written, or what has been written of him, that does not imagine to himself the countenance both of the apostle himself, and of all those whose names are there mentioned? And whereas, among such a multitude of men to whom these books are known, each imagines in a different way those bodily features and forms, it is assuredly uncertain which it is that imagines them more nearly and more like the reality. Nor, indeed, is our faith busied therein with the bodily countenance of those men; but only that by the grace of God they so lived and so acted as that Scripture witnesses: this it is which it is both useful to believe, and which must not be despaired of, and must be sought. For even the countenance of our Lord Himself in the flesh is variously fancied by the diversity of countless imaginations, which yet was one, whatever it was. Nor in our faith which we have of our Lord Jesus Christ, is that wholesome which the mind imagines for itself, perhaps far other than the reality, but that which we think of man according to his kind: for we have a notion of human nature implanted in us, as it were by rule, according to which we know forthwith, that whatever such thing we see is a man or the form of a man.
