Sacred Scripture far excels all other knowledge and teaching. It sets forth what is true; it calls readers to the heavenly country; it changes the hearts of readers from earthly desires to embrace things above; by its obscurer statements it exercises the strong and by its humble strain speaks gently to the little ones; it is neither so shut up that it should be dreaded nor so open to view as to be contemptible; use of it does not weary: the more it is meditated on the more it is loved; by its lowly words it assists a readers mind and uplifts it with lofty meanings; in a way it grows with the persons reading it; uninstructed readers find it familiar and yet the learned find in it something always new.(Gregory, Morals on Job, Bk. 20, 1:1)
Gregory found the same point made allegorically in the great vision in the first chapter of the Book of Ezekiel, where, after the four living creatures, wheels are seen (vv. 15ff), and after a difficult description of the wheels, the prophet reports this:
19 When the living creatures went, the wheels went beside them; and when the living creatures were lifted up from the earth, the wheels were lifted up. 20 Wherever the spirit wanted to go, they went, because there the spirit went; and the wheels were lifted together with them, for the spirit of the life was in the wheels. 21 When those went, these went; when those stood, these stood; and when those were lifted up from the earth, the wheels were lifted up together with them, for the spirit of life was in the wheels.
Gregory had already interpreted the living creatures to represent preachers of the Gospel and the wheels were the Sacred Scriptures, so that when it came to v. 19, he could say:
The living creatures go when holy men understand from the Scriptures how they are to live morally; they are lifted up from the earth when the holy men are suspended in contemplation. And because each one of the saints, the more he makes progress in the Scriptures, the more they make progress in him, it is rightly said: When the living creatures went, the wheels also went, and when the living creatures were lifted up from the earth, the wheels also were lifted up with them, because the Scriptures grow with the one who is reading them... The wheels are not lifted up if the living creatures are not lifted up, because unless the minds of those reading them make some progress upwards, the Scriptures lie in the depths, not understood....Wherever the spirit of the reader goes, there the Scriptures are lifted up, because if in them you seek to see and to sense something lofty, those same Scriptures grow with you, and with you rise toward loftier places. ...The wheels follow the spirit because the words of Scripture, as has already been said several times, grow in accordance with the understanding of those reading them. (Gregory on Ezekiel, Bk. I, Hom. 7, 8; PL 76, 843ff)
Even if one does not wish to follow Gregory in his allegorical flights, the insight is valid. What the Scriptures--or any other writing--can say to readers varies with their experience, learning, knowledge, wisdom--not to mention holiness. Susan Gannon reminded us yesterday that one never reads the same book twice, and that holds for the Bible, too.
