XV. (59) For Abraham also, having come with all haste and speech and eagerness, exhorts virtue, that is to say, Sarah, “to hasten and knead three measures of fine meal, and to make cakes upon the Hearth.”{29}{#ge 18:6.} When God, being attended by two of the heavenly powers as guards, to wit, by authority and goodness, he himself, the one God being between them, presented an appearance of the figures to the visual soul; each of which figures was not measured in any respect; for God cannot be circumscribed, nor are his powers capable of being defined by lines, but he himself measures everything. His goodness therefore is the measure of all good things, and his authority is the measures of things in subjection, and the Governor of the universe himself, is the measure of all things to the corporeal and incorporeal. On which account, his powers also having been looked upon in the light of rules and models, have weighed and measured other things with reference to them. (60) Now it is very good that these three measures should, as it were, be kneaded together in the soul, and mixed up together, in order that so the soul, being persuaded that the supreme being is God, who has raised his head above all his powers, and who is beheld independently of them, and who makes himself visible in them, may receive the characters of his power and beneficence, and becoming initiated into the perfect mysteries, may not be too ready to divulge the divine secrets to any one, but may treasure them up in herself, and keeping a check over her speech, may conceal them in silence; for the words of the scripture are, “To make secret cakes;” because the sacred and mystic statements about the one uncreated Being, and about his powers, ought to be kept secret; since it does not belong to every one to keep the deposit of divine mysteries properly.
