XXXVII. And having approached and standing by the cross he began to say: O name of the cross, thou hidden mystery! O grace ineffable that is pronounced in the name of the cross! O nature of man, that cannot be separated from God! O love (friendship) unspeakable and inseparable, that cannot be shown forth by unclean lips! I seize thee now, I that am at the end of my delivery hence (or, of my coming hither). I will declare thee, what thou art: I will not keep silence of the mystery of the cross which of old was shut and hidden from my soul. Let not the cross be unto you which hope in Christ, this which appeareth: for it is another thing, different from that which appeareth, even this passion which is according to that of Christ. And now above all, because ye that can hear are able to hear it of me, that am at the last and final hour of my life, hearken: Separate your souls from every thing that is of the senses, from every thing that appeareth, and does not exist in truth. Blind these eyes of yours, close these ears of yours, put away your doings that are seen; and ye shall perceive that which concerneth Christ, and the whole mystery of your salvation: and let thus much be said unto you that hear, as if it had not been spoken.
But now it is time for thee, Peter, to deliver up thy body unto them that take it. Receive it then, ye unto whom it belongeth. I beseech you the executioners, crucify me thus, with the head downward and not otherwise: and the reason wherefore, I will tell unto them that hear.
XXXVIII. And when they had hanged him up after the manner he desired, he began again to say: Ye men unto whom it belongeth to hear, hearken to that which I shall declare unto you at this especial time as I hang here. Learn ye the mystery of all nature, and the beginning of all things, what it was. For the first man, whose race I bear in mine appearance (or, of the race of whom I bear the likeness), fell (was borne) head downwards, and showed forth a manner of birth such as was not heretofore: for it was dead, having no motion. He, then, being pulled down -who also cast his first state down upon the earth- established this whole disposition of all things, being hanged up an image of the creation (Gk. vocation) wherein he made the things of the right hand into left hand and the left hand into right hand, and changed about all the marks of their nature, so that he thought those things that were not fair to be fair, and those that were in truth evil, to be good. Concerning which the Lord saith in a mystery: Unless ye make the things of the right hand as those of the left, and those of the left as those of the right, and those that are above as those below, and those that are behind as those that are before, ye shall not have knowedge of the kingdom.
This thought, therefore, have I declared unto you; and the figure wherein ye now see me hanging is the representation of that man that first came unto birth. Ye therefore, my beloved, and ye that hear me and that shall hear, ought to cease from your former error and return back again. For it is right to mount upon the cross of Christ, who is the word stretched out, the one and only, of whom the spirit saith: For what else is Christ, but the word, the sound of God? So that the word is the upright beam whereon I am crucified. And the sound is that which crosseth it, the nature of man. And the nail which holdeth the cross-tree unto the upright in the midst thereof is the conversion and repentance of man.
XXXIX. Now whereas thou hast made known and revealed these things unto me, O word of life, called now by me wood (or, word called now by me the tree of life), I give thee thanks, not with these lips that are nailed unto the cross, nor with this tongue by which truth and falsehood issue forth, nor with this word which cometh forth by means of art whose nature is material, but with that voice do I give thee thanks, O King, which is perceived (understood) in silence, which is not heard openly, which proceedeth not forth by organs of the body, which goeth not into ears of flesh, which is not heard of corruptible substance, which existeth not in the world, neither is sent forth upon earth, nor written in books, which is owned by one and not by another: but with this, O Jesu Christ, do I give thee thanks, with the silence of a voice, wherewith the spirit that is in me loveth thee, speaketh unto thee, seeth thee, and beseecheth thee. Thou art perceived of the spirit only, thou art unto me father, thou my mother, thou my brother, thou my friend, thou my bondsman, thou my steward: thou art the All and the All is in thee: and thou Art, and there is nought else that is save thee only.
Unto him therefore do ye also, brethren, flee, and if ye learn that in him alone ye exist, ye shall obtain those things whereof he saith unto you: 'which neither eye hath seen nor ear heard, neither have they entered into the heart of man.' We ask, therefore, for that which thou hast promised to give unto us, O thou undefiled Jesu. We praise thee, we give thee thanks, and confess to thee, glorifying thee, even we men that are yet without strength, for thou art God alone, and none other: to whom be glory now and unto all ages. Amen.
XL. And when the multitude that stood by pronounced the Amen with a great sound, together with the Amen Peter gave up his spirit unto the Lord.
