St. Augustine, from the Confessions, in conversation with his mother, St. Monica:
We were saying, then, If to any man the tumult of the flesh were silenced—silenced the phantasies of earth, waters, and air—silenced, too, the poles; yea, the very soul be silenced to herself, and go beyond herself by not thinking of herself—silenced fancies and imaginary revelations, every tongue, and every sign, and whatsoever exists by passing away, since, if any could hearken, all these say, "We created not ourselves, but were created by Him who abides for ever:" If, having uttered this, they now should be silenced, having only quickened our ears to Him who created them, and He alone speak not by them, but by Himself, that we may hear His word, not by fleshly tongue, nor angelic voice, nor sound of thunder, nor the obscurity of a similitude, but might hear Him— Him whom in these we love— without these, like as we two now strained ourselves, and with rapid thought touched on that Eternal Wisdom which remains over all. If this could be sustained, and other visions of a far different kind be withdrawn, and this one ravish, and absorb, and envelope its beholder amid these inward joys, so that his life might be eternally like that one moment of knowledge which we now sighed after, were not this "Enter into the joy of Your Lord"? (Matthew 25:21) And when shall that be? When we shall all rise again; but all shall not be changed.As pertinent now, in a crass and noisome age like ours, as when written 1600 years ago.
