3 But enough of this admonition. It is time now to deal with our subject; although our mind holds back and shrinks from giving this instruction, on account of those who are not come. And just as an affectionate mother when she is about to spread out her table, grieves and laments when all her children are not there, thus also do I now suffer; and when I think of the absence of our brethren, I am reluctant to discharge my debt. But you have it in your power to rid me of this tardiness.
For if you promise me that you will convey to them an exact report of all I say, we shall readily pay you down the whole; for thus the instructions, charitably afforded on your part, will make up to them for their absence; and you will hear me the more attentively, knowing that you must necessarily give an account of these things to others. In order then that our subject may be made the clearer, let us take it up and repeat it from the beginning. We were enquiring, then, the other day, On what account the Scriptures were delivered after so many years.
For this Book was delivered neither in the time of Adam, nor of Noah, nor of Abraham, but in that of Moses. And I hear many who say, that if the Book was profitable, it ought to have been delivered from the very beginning; but if it was useless, it ought not to have been delivered afterwards. But this is an obsolete argument; for it is not quite true that anything which is profitable ought to have been delivered from the beginning, nor if anything was delivered from the beginning, is it quite necessary that the same should continue afterwards. For example; Milk is useful, yet it is not always given; but it is given to us only when we are children; and solid food is useful; but no one ever gives it us in the beginning of our life, but when we have passed out of the age of childhood.
Again, the summer season is useful; but it does not show itself constantly; and the winter season is advantageous; yet this too makes room for others. What then? Do they say that the Scriptures are not useful? I reply; they are most useful and most necessary. And if so useful, for what reason then, say they, were they not delivered to us from the beginning? It was because God was desirous of instructing the nature of man, not by letters, but by things. But what does the expression “by things” signify? By means of the Creation itself.
