Ignatius to the Philadelphians

The priests likewise were good, but better is the High-priest to whom is committed the holy of holies; for to Him alone are committed the hidden things of God; He Himself being the door of the Father, through which Abraham and Isaac and Jacob enter in, and the Prophets and the Apostles and the whole Church; all these things combine in the unity of God.

Καλοὶ καὶ οἱ ἱερεῖς, κρεῖσσον δὲ ὁ ἀρχιερεὺς ὁ πεπιστευμένος τὰ ἅγια τῶν ἁγίων, ὃς μόνος πεπίστευται τὰ κρυπτὰ τοῦ θεοῦ: αὐτὸς ὢν θύρα τοῦ πατρός, δἰ ἧς εἰσέρχονται Ἀβραὰμ καὶ Ἰσαὰκ καὶ Ἰακὼβ καὶ οἱ προφῆται καὶ ἀπόστολοι καὶ ἡ ἐκκλησία. πάντα ταῦτα εἰς ἑνότητα θεοῦ.
