Clement of Alexandria Almost Reveals What Went On In the Inner Sanctum of the Martyrium of St. Mark in Alexandria

"Now I pass over other things in silence (σιγῶ), glorifying the Lord. But I affirm that gnostic souls (τὰς γνωστικὰς ψυχάς), that surpass in the grandeur of contemplation the mode of life of each of the holy ranks, among whom the blessed abodes of the gods (μακάριαι θεῶν οἰκήσεις) are allotted by distribution, reckoned holy among the holy, transferred entire from among the entire, reaching places better than the better places, embracing the divine vision not in mirrors or by means of mirrors, but in the transcendently clear and absolutely pure insatiable vision which is the privilege of intensely loving souls (ἀγαπώσαις ψυχαῖς), holding festival through endless ages (εἰς τοὺς ἀτελευτήτους αἰῶνας), remain honoured with the indentity of all excellence. Such is the vision attainable by "the pure in heart." This is the function of the Gnostic who has been perfected (τοῦ τελειωθέντος γνωστικοῦ), to have convene with God through the great High Priest (προσομιλεῖν τῷ θεῷ διὰ τοῦ μεγάλου ἀρχιερέως), being made like the Lord, up to the measure of his capacity, in the whole service of God, which tends to the salvation of men, through care of the beneficence which has us for its object; and on the other side through worship, through teaching and through beneficence in deeds. The Gnostic even forms and creates himself and besides also, he, like to God, adorns those who hear him." [Stromata 7.3]
