The implication seems to be that the very same 'Man' who was strange or unknown to the Jews was at once the holder of the name which is above all names. The implication seems to be the Jews will call him 'Lord' because he is 'just' to them (i.e. punishes them) but to the Christians he is merciful and known by another name - Man.They say, too, that Here delights in the lily, and Artemis in the myrtle. For if the flowers were made especially for man, and senseless people have taken them not for their own proper and grateful use, but have abused them to the thankless service of demons, we must keep from them for conscience sake. The crown is the symbol of untroubled tranquillity. For this reason they crown the dead, and idols, too, on the same account, by this fact giving testimony to their being dead. For revellers do not without crowns celebrate their orgies; and when once they are encircled with flowers, at last they are inflamed excessively. We must have no communion with demons. Nor must we crown the living image of God after the manner of dead idols. For the fair crown of amaranth is laid up for those who have lived well. This flower the earth is not able to bear; heaven alone is competent to produce it. Further, it were irrational in us, who have heard that the Lord was crowned with thorns, Matthew 27:29 to crown ourselves with flowers, insulting thus the sacred passion of the Lord. For the Lord's crown prophetically pointed to us, who once were barren, but are placed around Him through the Church of which He is the Head. But it is also a type of faith, of life in respect of the substance of the wood, of joy in respect of the appellation of crown, of danger in respect of the thorn, for there is no approaching to the Word without blood. But this platted crown fades, and the plait of perversity is untied, and the flower withers. For the glory of those who have not believed on the Lord (τῷ κυρίῳ μὴ πεπιστευκότων) fades. And they crowned ΙΣ raised aloft, testifying to their own ignorance. For being hard of heart, they understood not that this very thing, which they called the disgrace of the Lord, was a prophecy wisely uttered: The Lord was not known by the people which erred [Isaiah 1:3], which was not circumcised in understanding, whose darkness was not enlightened, which knew not God, denied the Lord, forfeited the place of the true Israel, persecuted God, hoped to reduce the Word to disgrace; and Him whom they crucified as a malefactor they crowned as a king. Wherefore the Man on whom they believed not (οὐκ ἐπίστευσαν ἄνθρωπον), the man-loving God they shall know to be the Lord, the Just (τὸν φιλάνθρωπον θεὸν ἐπιγνώσονται κύριον καὶ δίκαιον). Whom they provoked to show Himself to be the Lord (ὅτι αὐτοὶ παρεπίκραναν ἐπιδείξασθαι τὸν κύριον), to Him when lifted up they bore witness (τοῦτο αὐτῷ ὑψουμένῳ μεμαρτυρήκασι) with the diadem of righteousness who is exalted above every name by encircling Him (τῷ ὑπὲρ πᾶν ὄνομα ἐπηρμένῳ περιάψαντες) with the ever-blooming thorn (διὰ τῆς ἀειθαλοῦς ἀκάνθης). This diadem, being hostile to those who plot against Him, coerces them; and friendly to those who form the Church, defends them. This crown is the flower of those who have believed on the glorified One, but covers with blood and chastises those who have not believed. It is a symbol, too, of the Lord's successful work, He having borne on His head, the princely part of His body, all our iniquities by which we were pierced. For He by His own passion rescued us from offenses, and sins, and such like thorns; and having destroyed the devil, deservedly said in triumph, O Death, where is your sting? 1 Corinthians 15:55 And we eat grapes from thorns, and figs from thistles; while those to whom He stretched forth His hands — the disobedient and unfruitful people — He lacerates into wounds. I can also show you another mystic meaning in it. For when the Almighty Lord of the universe began to legislate by the Word, and wished His power to be manifested to Moses, a godlike vision of light that had assumed a shape was shown him in the burning bush (the bush is a thorny plant); but when the Word ended the giving of the law and His stay with men, the Lord was again mystically crowned with thorn. On His departure from this world to the place whence He came, He repeated the beginning of His old descent, in order that the Word beheld at first in the bush, and afterwards taken up crowned by the thorn, might show the whole to be the work of one power, He Himself being one, the Son of the Father, who is truly one, the beginning and the end of time. [Clement Instructor 2.8]
There is a strong parallel with a passage in Philo - that Clement copies out verbatim as his own teaching - where it is understood that Jacob when he finally sees god on the heavenly ladder no longer sees him as Yahweh - 'Lord' - but instead Man or Elohim. Philo understands him to be singing a song acknowledging his change of understanding.
