Bede : Figuratively, the curtain in the temple represents the same curtain that the apostle declares openly to the Hebrews, in the place where he also explains properly, according to the allegorical sense, the reason that "the priests go continually into the outer tent, performing their ritual duties, but into the second only the high priest goes, and he but once a year, and not without taking blood which he offers for himself and for the errors of the people." This curtain is interpreted as heaven. And the priests entered into the first tabernacle with sacrifices daily throughout the year, which further illustrates the circumstances of this life, in which the saints who serve the Lord as true priests of God and of his Christ ceaselessly atone for the daily errors of their frailty, without which they are by no means able to exist in this life through the daily sacrifices of good works and the daily libations of their own tears. But the apostle understands the high priest who went into the Holy of Holies with the blood of victims once a year to be the great high priest himself, of whom it was said, "You are a priest forever after the order of Melchizedek." He who as both priest and victim had offered himself through his own blood once for our sins entered "into heaven itself, now to appear in the presence of God on our behalf." — On the Tabernacle 2.8.71 John Chrysostom : "Now when these things were thus ordained, the priests went always into the first tabernacle accomplishing the service of God." That is, these things indeed were there, but the Jews did not enjoy them: they saw them not. So that they were no more theirs than ours for whom they prophesied. — Homily on Hebrews 15 Oecumenius : And it happened that the Jews neither saw the things that were happening, as the veil was being torn. So it was not more for them than for those who were prefigured, that is, for us, "once a year, the high priest alone." Since he approached them while they were still infants, how could one sacrifice of Christ cleanse the sins of the world? This is also shown in the old, which is a type of the new. — The Pseudo-Oecumenian Catena on Hebrews Oecumenius : In Exodus, in the places concerning these things, it says that on the day the high priest entered the Holy of Holies with the holy incense. And it is written thus; "And he shall burn incense upon it." (that is, upon the golden altar that was in the Holy of Holies); Aaron shall burn a finely blended incense in the morning when he tends to the lamps, he shall burn incense upon it. And when Aaron lights the lamps in the evening, he shall burn incense, a continual incense. (Ex. 30:10) — The Pseudo-Oecumenian Catena on Hebrews Oecumenius : How then does the divine Paul say in this place, "once a year, the high priest alone?" And we say that he indeed entered with blood once a year: as is also said in the aforementioned place of Exodus; but to offer, on these days every day. Indeed, he also adds here: "not without blood," that is, with blood; so that this is the sense: Once a year the high priest with blood, not with incense. "without blood." After sacrifices, he says. So also the blood was a type of Christ. "which he offers for himself." He adds everywhere, For himself, showing Christ's excellence above the high priest of the Jews.For the legal high priest offered for himself; but Christ did not offer for himself; for how could he, who is separate from sinners? Thus there is a great difference between the two. "and of the ignorance of the people", he says. And from this, he shows the difference, that the sacrifices according to the law were offered for ignorance. For those in ignorance were allowed sins, indeed, the sacrifice of Christ, even those sins whom we knowingly have committed. — The Pseudo-Oecumenian Catena on Hebrews
