26 These things I have written according to what I have attained to. But if anyone shall read these discourses, and find words that do not agree with his thought, he ought not to scorn them; because whatsoever is written in these chapters was not written according to the thought of one man, nor for the persuasion of one reader; but according to the thought of all the Church, and for the persuasion of all faith. If he shall read and hear with persuasion, it is well; and if not, it is meet for me to say that I wrote for those open to persuasion and not for mockers.
And if again any reader should find words that are spoken by us in one fashion, and by another sage in another fashion, let him not be disturbed at this; for every man speaks to his hearers according to what he can attain to. So I, who have written these things, even if some of the words do not agree with what other speakers have said, yet say this; that those sages have spoken well, yet it seemed good to me to speak thus. And if any man shall speak and demonstrate to me about any matter, I will receive instruction from him without contention.
Everyone who reads the sacred scriptures, both former and latter, in both covenants, and reads with persuasion, will learn and teach. But if he strives about anything that he does not understand, his mind does not receive teaching. But if he finds words that are too difficult for him, and he does not understand their force, let him say thus, “Whatsoever is written is written well, but I have not attained to the understanding of it.” And if he shall ask about the matters that are too hard for him of wise and discerning men who inquire into doctrine, then, when ten wise men shall speak to him in ten different ways about one matter, let him accept that which pleases him; and if any please not him, let him not scorn the sages; for the word of God is like a pearl, that has a beautiful appearance on whatever side you turn it.
And remember, O disciple, what David said, From all my teachers have I learned. And the Apostle said:— Read every Scripture that is in the Spirit of God. And prove everything; hold fast that which is good; and flee from every evil thing. For if the days of a man should be many as all the days of the world from Adam to the end of the ages, and he should sit and meditate upon the Holy Scriptures, he would not comprehend all the force of the depth of the words.
And man cannot rise up to the wisdom of God; as I have written in the tenth discourse. But, however, the words of all speakers who do not take from the great treasure, are accursed and to be despised. For the image of the king (on his coin) is received wherever it goes; but (the coin) in which there is base metal, is rejected and is not received. And if any one should say, “These discourses were spoken by such an one;” let him carefully learn that to be careful to inquire about the speaker is not commanded him.
I also according to my insignificance have written these things, a man sprung from Adam, and fashioned by the hands of God, a disciple of the Holy Scriptures. For our Lord said:— Every one that asks receives, and he that seeks finds, and for him that knocks it shall be opened. And the prophet said:— I will pour out my spirit upon all flesh in the last days, and they shall prophesy. Therefore whoever shall read anything that I have written above, let him read with persuasion, and pray for the author as a brother of the Body; that through the petition of all the Church of God; his sins may be forgiven.
And let whoever reads understand what is written:— Let him that hears the word, communicate to him that causes him to hear, in all good things. And again it is written, The sower and the reaper shall rejoice together. And Every man according to his labours shall receive his reward. And There is nothing hidden that shall not be revealed to every man.
