1 Yesterday, so far as the Lord vouchsafed to bestow, we discussed with what ability we could, and discerned according to our capacity, how the works of the Father and of the Son are inseparable; and how the Father does not some, the Son others, but that the Father does all things through the Son, as through His Word, of which it is written, “All things were made by Him, and without Him was nothing made.” Let us today look at the words that follow. And of the same Lord let us pray for mercy, and hope that, if He deem it meet, we may understand what is true; but if we should not be able to do this, that we may not go into what is false.
For it is better not to know than to go astray; but to know is better than not to know. Therefore, before all things, we ought to strive to know. Should we be able, to God be thanks; but should we not be able meanwhile to arrive at the truth, let us not go to falsehood. For we are bound to consider well what we are, and what we are treating of. We are men bearing flesh, walking in this life; and though now begotten again of the seed of the Word of God, yet in Christ renewed in such manner that we are not yet wholly rid of Adam.
For truly our mortal and corruptible part that weighs down the soul shows itself to be, and manifestly is, of Adam; but what in us is spiritual, and raises up the soul, is of God's gift and of His mercy, who has sent His only Son to partake our death with us, and to lead us to His own immortality. The Son we have for our Master, that we may not sin; and for our defender, if we have sinned and have confessed, and been converted; an intercessor for us, if we have desired any good of God; and the bestower of it with the Father, because Father and Son is one God.
But He was speaking these things as man to men: God concealed, the man manifest, that He might make them gods that are manifest men; and the Son of God made Son of man, that He might make the sons of men sons of God. By what skill of His wisdom He does this, we perceive in His own words. For as a little one He speaks to little ones, but Himself little in such wise that He is also great, and we little, but in Him great. He speaks, in deed as one cherishing and nourishing children at the breast that grow by loving.
