As, then, the virtues follow one another, why need I say what has been demonstrated already, that faith hopes through repentance, and fear through faith; and patience and practice in these along with learning terminate in love, which is perfected by knowledge? But that is necessarily to be noticed, that the Divine alone is to be regarded as naturally wise. Therefore also wisdom, which has taught the truth, is the power of God; and in it the perfection of knowledge is embraced. The philosopher loves and likes the truth, being now considered as a friend, on account of his love, from his being a true servant. The beginning of knowledge is wondering at objects, as Plato says in his _Theætetus_; and Matthew exhorting in the _Traditions_, says, “Wonder at what is before you;” laying this down first as the foundation of further knowledge. So also in the Gospel to the Hebrews it is written, “He that wonders shall reign, and he that has reigned shall rest.” It is impossible, therefore, for an ignorant man, while he remains ignorant, to philosophize, not having apprehended the idea of wisdom; since philosophy is an effort to grasp that which truly is, and the studies that conduce thereto. And it is not the rendering of one[97] accomplished in good habits of conduct, but the knowing how we are to use and act and labour, according as one is assimilated to God. I mean God the Saviour, by serving the God of the universe through the High Priest, the Word, by whom what is in truth good and right is beheld. Piety is conduct suitable and corresponding to God.
