14 But you are perhaps longing for me to give an exposition of the faith, in so far as I am able. For I shall myself be sanctified by the effort of memory, and the people also will be benefited, by its special delight in such discussions, and you will fully acknowledge it— unless we are the objects of groundless envy, as the rivals, in the manifestation of the truth, of those whom we do not excel. For as, of deep waters, some in the depths are utterly hidden, some foam against any obstruction, and hesitate a while before breaking (as they promise to our ears), some do actually break; so also, of those who are professors of the Divine philosophy— setting aside the utterly misguided— some keep their piety entirely secret and hidden within themselves, some are not far from the birth pangs, avoiding impiety, yet not speaking out their piety, either from cautious reserve in their teaching, or under pressure of fear, being themselves sound, as they say, in mind, but not making sound their people, as if they had been entrusted with the government of their own souls, but not of those of others; while there are some who make public their treasure, unable to restrain themselves from giving birth to their piety, and not considering that to be salvation which saves themselves alone, without bestowing upon others the overflow of their blessings. Among these would I range myself, and all who by my side have nobly dared to confess the truth.
