Chapter 1 [I.]—Introductory. I Have read your letter—Valentine, my dearly beloved brother, and you who are associated with him in the service of God—which your Love sent by brother Florus and those who came to us with him; and I gave God thanks that I have known your peace in the Lord and agreement in the truth and ardour in love, by your discourse delivered to us. But that an enemy has striven among you to the subversion of some, has, by the mercy of God and His marvellous goodness in turning his arts to the advantage 3236 of His servants, rather availed to this result, that while none of you were cast down for the worse, some were built up for the better. There is therefore no need to reconsider again and again all that I have already transmitted to you, sufficiently argued out in a lengthy treatise; 3237 for your replies indicate how you have received this. Nevertheless, do not in any wise suppose that, when once read, it can have become sufficiently well known to you. Therefore if you desire to have it exceedingly productive, do not count it a grievance by re-perusal to make it thoroughly familiar; so that you may most accurately 3238 know what and what kind of questions they are, for the solution and satisfaction of which there arises an authority not human but divine, from which we ought not to depart if we desire to attain to the point whither we are tending. 3236     Or according to some mss. , “progress.” 3237     Treatise on Grace and Free Will , see above. 3238     Or, “most clearly.”
