LXX Lev 16:4:"A consecrated linen tunic will be put on.” (Tunica inquit linea sanctificata induetur Lev 16.4)
Linen rises up from the earth (linum de terra oritur) a sanctified linen tunic that Christ puts on (tunica ergo sanctificata linea induitur uerus pontifex Christus), with the nature of an earthly body (cum naturam terreni corporis sumit). Remember that it is said about the body that it is earth and it will go into the earth. (de corpore enim dicitur quia terra sit et in terram ibit cf. Genesis 3:19) Therefore my Lord and Savior, wanting to resurrect that which had gone into the earth, took an earthly body that he might carry it raised up from the earth to heaven (Volens ergo Dominus et Saluator meus hoc, quod in terram ierat, resuscitare terrenum suscepit corpus, ut id eleuatum de terra portaret ad caelum).
And the assertion in the Law that the high priest is clothed "with a linen tunic" contains a a figure of this mystery (Et huius mysterii tenet figuram hoc quod in lege scribitur, ut linea tunica pontifex induatur). But that it added "sanctified" must not be heard as superfluous (Sed quod addidit: sanctificata, non otiose audiendum est). For "the tunic" that was the flesh of Christ was "sanctified," for it was not conceived from the seed of man but begotten of the Holy Spirit (Sanctificata namque fuit tunica carnis Christi; non enim erat ex semine uiri concepta, sed ex sancto Spiritu generata).
The root of the word for bathe here is λούω. The closest passage which conforms to what Origen is suggesting is Secret Mark:And he shall put on the consecrated linen tunic, and he shall have on his flesh the linen drawers, and shall gird himself with a linen girdle, and shall put on the linen cap, they are holy garments
and he shall bathe all his body in water, and shall put them on.
καὶ χιτῶνα λινοῦν ἡγιασμένον ἐνδύσεται καὶ περισκελὲς λινοῦν ἔσται ἐπὶ τοῦ χρωτὸς αὐτοῦ καὶ ζώνῃ λινῇ ζώσεται καὶ κίδαριν λινῆν περιθήσεται ἱμάτια ἅγιά
ἐστιν καὶ λούσεται ὕδατι πᾶν τὸ σῶμα αὐτοῦ καὶ ἐνδύσεται αὐτά
Notice that the body is 'in the earth' (= Jesus raised him). This conforms exactly to the idea of a body raised and resurrected from the earth as in Origen. Notice also the linen cloth and the concept of 'resurrecting.' While it is unfortunate that we don't have the original Greek, there can be no doubt that it is this passage of all gospel passages which most closely resembles the act of Jesus that Origen has in mind related to the ceremonial washing of the priests and this is further confirmed by the context in which Clement places the ritual in Secret Mark,Jesus went off with her into the garden where the tomb was (Ἰησοῦς ἀπῆλθεν μετ᾽ αὐτῆς εἰς τὸν κῆπον ὅπου ἦν τὸ μνημεῖον), and straightway a great cry was heard from the tomb. And going near, Jesus rolled away the stone from the door of the tomb. And straightaway, going in where the youth was, he stretched forth his hand and raised him (ἐξέτεινεν τὴν χεῖρα καὶ ἤγειρεν αὐτὸν), seizing his hand. But the youth, looking upon him, loved him and began to beseech him that he might be with him. And going out of the tomb, they came into the house of the youth, for he was rich. And after six days Jesus told him what to do, and in the evening the youth comes to him, wearing a linen cloth over his naked body (ὁ νεανίσκος πρὸς αὐτὸν περιβεβλημένος σινδόνα ἐπὶ γυμνῷ). And he remained with him that night, for Jesus taught him the mystery of the Kingdom of God. And rising (Ἐκεῖθεν δὲ ἀναστὰς), he returned to the other side of the Jordan.
Clement associates the rite with "the hierophantic teaching of the Lord" which are in turn are associated with "the adyton (holy of holies) of truth hidden by seven veils" (τὸ ἄδυτον τῆς ἑπτάκις κεκαλυμμένης ἀληθείας). Of course the high priest is washing and redressing in the very same place in the Leviticus 16 rite and interestingly Clement says of that rite in the Stromata:
While Clement doesn't specifically reference the concept of 'resurrection' there can be no doubt given Clement's explicit reference to Secret Mark in the Letter to Theodore that he and Origen are talking about the same thing. There is a basic understanding that Jesus and a disciple had an experience similar to what transpired when the high priest entered the Holy of Holies of the tabernacle once in the year (= Yom Kippur).And they say that the robe prophesied the ministry in the flesh, by which He (the Logos) was seen in closer relation to the world. So the high priest, putting off his consecrated robe (the universe, and the creation in the universe, were consecrated by Him assenting that, what was made, was good), washes himself (λούεται), and puts on the other tunic -- a holy-of holies one (ἅγιον ἁγίου), so to speak -- which is to accompany him into the adytum (τὰ ἄδυτα); exhibiting, as seems to me, the Levite and Gnostic, as the chief of other priests (those bathed in water, and clothed in faith alone, and expecting their own individual abode), himself distinguishing the objects of the intellect from the things of sense, rising above other priests, hasting to the entrance to the world of ideas, to wash himself from the things here below, not in water, as formerly one was cleansed on being enrolled in the tribe of Levi.
But purified (καθαρὸς) already by the gnostic Word (τῷ γνωστικῷ λόγῳ) in his whole heart, and set up right (κατορθώσας), and having improved that mode of life received from the priest to the highest pitch, being quite sanctified (ἡγνισμένος) both in word and life, and having put on the bright array of glory (ἐπενδυσάμενος τὸ γάνωμα τῆς δόξης), and received the ineffable inheritance of that spiritual and perfect man (τοῦ πνευματικοῦ ἐκείνου καὶ τελείου ἀνδρὸς τὴν ἀπόρρητον κληρονομίαν ἀπολαβών), "which eye hath not seen and ear hath not heard, and it hath not entered into the heart of man;" and having become son and friend (υἱὸς καὶ φίλος γενόμενος), he is now replenished with insatiable contemplation face to face (πρόσωπον ἤδη πρὸς πρόσωπον ἐμπίπλαται τῆς ἀκορέστου θεωρίας).
For there is nothing like hearing the Word Himself, who by means of the Scripture inspires fuller intelligence. For so it is said, "And he shall put off the linen robe, which he had put on when he entered into the holy place; and shall lay it aside there, and wash his body in water in the holy place, and put on his robe." But in one way, as I think, the Lord puts off and puts on by descending into the region of sense; and in another, he who through Him has believed puts off and puts on, as the apostle intimated, the consecrated stole. Thence, after the image of the Lord. the worthiest were chosen from the sacred tribes to be high priests, and those elected to the kingly office and to prophecy were anointed. [Stromata 5.6.39.2 - 5.6.40.4]
This is what isn't grasped by most people in the debate. Everyone accepts that there was a basic understanding regarding the applicability of the high priest entering the holy of holies bathing and seeing God AND the Christian experience. Look at Mazur notes about the Alexandrian tradition:
When you start to calculate how much damage to Smith's scholarly reputation merely because a bunch of uptight Christian scholars saw the word 'naked' and peed their pants it is simply astounding. Clearly Clement, Origen and Valentinians before them understood the nakedness of the Jewish high priest during the ritual immersion in the holy of holies as being passed on to Christian initiates at baptism. It is incredible that this charade has gone on as long as it has.Philo formulates a Platonizing allegory on the basis of the passages of Leviticus that prescribe the ritual procedures to be performed by the high priest upon entering the tabernacle. The priest, according to Philo, must remove his garments that symbolize the lower faculties of opinion (δόξα) and imagination (φαντασία) prior to entering the Holy of Holies, which apparently represents the intelligible realm;68 at this point, “he will enter naked, without colors or sounds, to offer up psychic blood, and to sacrifice the whole intellect to the salvific and beneficent God.”69 Signifi— cantly, Dodds also adduced a clearly related passage of Clement's Excerpta ex Theodoto that he believed to reflect the doctrine of the Valentinian heresiarch Theodotus himself. Thus at Exc. 26.2—27.3, the high priest (identified with the Monogenes—Son) is said to remove not garments but a gold plate on which is inscribed the Tetragrammaton (the Name of God) at the precise moment he passes through the “second veil” which separates the antechamber (the “Holy Place”) of the tabernacle from the Holy of Holies itself.70 The high priest is subsequently compared to the ascending soul, which, once “naked” (yuuvrj), enters into the spiritual realm.71 Dodds therefore suggested that a Valentinian allegory of the sort one finds in the text of Clement/Theodotus served as the more immediate source for Plotinus' ritual imagery at 1.6.[1]7.
As reasonable as this hypothesis might seem however it has been largely ignored by subsequent commentators. in part, one may presume, be- cause of the widespread but (in my view) overly-simplistic assumption of Plotinus' fundamental antipathy toward the Gnostics (which, if correct, would render such a borrowing implausible),but also because of the recognition that the process by which the motif was transmitted between its ostensibly Philonic origin and its eventual Plotinian iteration must have been considerably more complex than Dodds had originally supposed. In 1970, F. Sagnard observed that the allegorical interpretation of the high priest's ritual divestiture of the sort we find in the Excerpta occurs elsewhere in Clement, at Strom. 5.6.32.1–40.4, in a passage which clearly expresses Clement's own thought and not merely that of his Valentinian source:74 “So the high priest, shedding his consecrated tunic ... bathes himself and puts on his other, so to speak,'Holy of Holies' tunic, and he enters together into the adyton with it." Sagnard further demonstrated that the entirety of this extended passage echoes another Philonic passage originally neglected by Dodds, Mos.2.95–135, in which Philo allegorizes certain passages of the Pentateuch (especially Exod 25–31, 35 - 39, and Lev 8) that describe the sacrificial procedures and ritual paraphernalia attending the high priest's entrance into the Holy of Holies.

The logical inference here is that the catechumen were immersed into a rite understood to have been originally associated with the Jewish high priest. This is undoubtedly why in many early Christian cultures baptism takes place away from the unbaptized in a secret chamber mirroring the 'holy of holies.'
