Mark 15:38

And the veil of the temple was rent in two from the top to the bottom.

This is numbered among the Calvary miracles, and a full treatment of the extensive symbolism of this event is found in my Commentary on Matthew, Matthew 27:53. Briefly, the veil symbolized the flesh of Christ himself, through which a new and living way has been opened for Christians (Hebrews 10:19). It means that the Old Testament must be understood in the light of the New Testament (2 Corinthians 3:14-16). It signifies the abolition of the old covenant, the victory over death, the rending of Christ's flesh in his death, and the granting of access of Christians to the presence of God himself.
