32 Of this garden I sang of old to My spouse in the Canticles, and spoke to her thus. I have come into My garden, My sister, My spouse; (now in the place where He was crucified was a garden;) and what takest Thou thence? I have gathered My myrrh; having drunk wine mingled with myrrh, and vinegar, after receiving which, He said, It is finished. For the mystery has been fulfilled; the things that are written have been accomplished; sins are forgiven.
For Christ having come an High-Priest of the good things to come, by the greater and more perfect tabernacle, not made with hands, that is to say, not of this creation, nor yet by the blood of goats and calves, but by His own blood, entered in once for all into the holy place, having obtained eternal redemption; for if the blood of bulls and of goats, and the ashes of an heifer, sprinkling the defiled, sanctifies to the purifying of the flesh, how much more the blood of Christ?
And again, Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus, by a new and living way, which He has consecrated for us, through the veil, that is to say, His flesh. And because His flesh, this veil, was dishonoured, therefore the typical veil of the temple was rent asunder, as it is written, And, behold, the veil of the temple was rent in two from the top to the bottom; for not a particle of it was left; for since the Master said, Behold, your house is left unto you desolate, the house broke all in pieces.
