9 Ten treatises have I written unto you, my beloved. Whatsoever you have asked of me, I have explained to you without (receiving) ought from you. And that which you enquired not of me, I have given unto you. I have asked your name and written unto you. I have asked of myself your question, and I have answered you as I was able, for your persuasion. Whatsoever I have written unto you, meditate in these things at every time; and labour to read those books which are read in the church of God.
These ten little books that I have written for you, they borrow one from another, and depend one upon another. Separate them not one from another. From Olaph to Yud I have written for you, each letter after its fellow. Read and learn, you and the brethren, the monks, and the faithful, they from whom mocking is far removed; as I wrote unto you above. And remember that which I pointed out to you, that I have not brought these matters to an end, but short of the end. Nor are these things sufficient; but hear these things from me without wrangling, and enquire concerning them with brethren who are apt for persuasion.
Whatsoever you hear that assuredly edifies, receive; and whatever builds up strange doctrines, overthrow and utterly demolish. For wrangling cannot edify. But I, my beloved, as a stonecutter have brought stones for the building, and let wise architects carve them out and lay them in the building; and all the labourers that toil in the building shall receive reward from the Lord of the house.
