St. Mark, the gospel writer, noted that when Jesus died:

Jesus cried with a loud voice, and gave up the ghost.
And the veil of the temple was rent in twain from the top to the bottom.
(Mark 15: 37-38)

In three of the four accounts of Jesus’ crucifixion, we have a mention of the curious fact of the rending of the temple veil, or curtain. The curtain in view here is probably the barrier that guarded the entrance to the “holy of Holies”, the most sacred part of the Hebrew Tabernacle (and later, the Temple in Jerusalem). Within this chamber resided the Ark of the Covenant (until it became lost to history). This chamber represented the presence of God. No one was allowed to enter except the High Priest, and even he could only enter once a year on Yom Kippur (the great “Day of Atonement”). The barrier was for the protection of the people, who could not survive a direct encounter with the presence of God.

Ancient Jewish tradition would suggest that this barrier was formidable (though debate about the thickness exists; see a full discussion by Baptist seminarian Charles Bumgardner at his blog). It is unclear whether the veil was a single thick panel, or a single panel hung in such a way as to create a maze. It may even have been two panels. (For a lengthy discussion, see the article “The Veil of the Temple in History and Legend” by Daniel M. Gurtner).

According to a 2014 news report, a group of women in Israel are struggling with the challenge of recreating the Veil: “The women of the veil chamber,” as they call themselves, have founded a little workshop in the biblical Samarian community of Shiloh that is filled with weaving devices and wool. . This curtain is no thin wisp of cloth: The size of the veil itself, a single rag-like object measuring 20 meters high, 10 meters wide and 10 centimeters thick, is a project of immense complexity in and of itself.
(From Israel Today. I have not found any follow up reporting on their progress).

I might pause to note that some debate also exists also as to which curtain was torn. Some early theologians, such as St. Thomas Aquinas, believed that the torn curtain was not the one protecting the Holy of Holies, but a more visible and external curtain, hanging in front of the outer courts. There would have been two curtains in the temple, since the temple followed biblical blueprints initially given for its predecessor, the mobile Tent of Meeting (or Tabernacle): “You shall make a screen for the entrance of the tent, of blue and purple and scarlet yarns and fine twined linen, embroidered with needlework.” (Exodus 26:36, English Standard Version)

In his Commentary on St. Matthew, Aquinas noted that the deepest mysteries still remain hid from us:

And these two veils signify a twofold veiling, because the inside veil signifies the veiling of heavenly mysteries, which will be revealed to us: for then we shall be like to Him, when His glory shall have appeared. The other veil, which was outside, signifies the veiling of mysteries which pertain to the Church. Hence, the outer veil was rent, but the other one was not, to signify that mysteries which pertain to the Church were made known by Christ’s death; but the other veil was not rent, because heavenly secrets still remain veiled. Hence, the Apostle says: “But when Israel shall be converted to the Lord, the veil shall be taken away” (II Cor. 3, 16). Hence, by the Passion, all mysteries, which were written in the Law and the prophets, were opened, as it is stated: “Beginning at Moses and all the prophets, he expounded to them in all the scriptures the things that were concerning him” (Lk. 24, 27).
(St Thomas Aquinas, Commentary on St. Matthew, available online).

The important point for us isn’t the nature or location of the curtain, but rather the deeper meaning and symbolism behind its rupture. Even this may have multiple layers of possibilities. As I was preparing this article, I discovered one blog article that linked the tearing of the veil to the Jewish custom of tearing one’s clothes at a time of great distress, such as grief from the death of a loved one. The idea is that God was tearing His clothes at a moment of deep anguish.

A more common interpretation would be something like this:

The rending of this veil means that access into the presence of God is no longer limited to the high priest; in the era after Christ’s death, all believers may boldly come before the Almighty’s throne. … Clearly, with the death of Jesus a cataclysmic change happened in the way we approach the Father, as well as with God’s relationship to the temple. It was, John Calvin writes, “an opening of heaven, that God may now invite the members of his Son to approach him with familiarity.” (R.C. Sproul, Ligonier Ministries).

Jesus’ death has accomplished something wondrous. God has destroyed the barrier that separates us from His presence.
