What tabernacle does he call greater, more perfect, and not made with hands, that is, not of this creation? Chrysostom, Theodoret, Oecumenius, and Theophylact say that he called the very flesh of the Lord Jesus the tabernacle.
He called it so because in it "all the fullness of the Godhead" settled and dwelt (Col 2:9).
He called it greater and more perfect because the flesh of God the Word incomparably surpasses the lawful tabernacle.
Through the Passion and death of His flesh, God accomplished works incomparably more perfect than those performed in the tabernacle.
He called it not made with hands because it was not skillfully constructed by human hands, as the lawful tabernacle was by Bezalel and Eliab (Ex 36:2).
What does the explanatory phrase mean: "that is, not of this creation"?
It means that the flesh of the Giver of Life received its being not according to the laws of nature, that is, from the union of man and woman, as human bodies do.
Rather, it was composed and fashioned from the most pure blood of the Ever-Virgin Mary, by the descent of the All-Holy Spirit and the overshadowing of the power of the Most High (Lk 1:35).
Here is another superiority of the sacrifice. The typical legal sacrifice was accomplished with the blood of goats and calves, but the true sacrifice of Jesus Christ with His own blood.
The lawful high priest enters the Holies in the tabernacle, offering the blood of goats and calves (Lev 16:14, 18).
But Jesus, the High Priest of grace, after offering His divine blood, ascended into heaven.
To show the difficulty and arduousness of our redemption, he said "having obtained." So it happens among men: when they accomplish difficult and troublesome tasks, they regard it as a finding and say, "We have obtained it."
He called our redemption eternal because, having once been redeemed, we remain free forever. There is no need whatever for another sacrifice to be offered for our redemption.
This, then, is the complete meaning of the Apostle's present words.
Christ, he says, came into the world so that, as High Priest, He might offer Himself in sacrifice, not for worldly and temporal goods, but for the heavenly and unending goods of the age to come.
With His assumed flesh, which is greater and more perfect than the lawful tabernacle, and which was formed supernaturally and not according to the law of nature, He ascended.
He ascended not "once a year" (Heb 9:7), as the lawful high priest did, but only once.
He ascended not into the tabernacle, but into the Holies, that is, "at the right hand of the throne of the Majesty in the heavens" (Heb 8:1).
He ascended offering not the blood of goats and calves, but His own blood, poured out on the Cross.
By this sacrifice He granted the human race eternal redemption from the slavery of Satan and the endless glory of divine blessedness.
Having said this, he brings forward a proof taken from the lesser to the greater.
