The foundation of the great abomination of desolation rests in the doctrine of the Mass. The Mass substitutes human  (priests’) performances in place of the great sacrifice of Calvary, for the cleansing away of sin. Jesus’ sacrifice was “once for all,” Romans 6:10. “For Christ also suffered once for sins, the just for the unjust…” 1 Peter 3:18. The “priest” in the mass re-sacrifices Jesus on the “altar” every single time. This is an abomination to God.​

There is great significance in our Lord’s words – “When therefore ye see (understand or recognize the error of the Mass) the abomination of the desolation having stood in the holy place, as foretold by Daniel the Prophet (reader consider): Then let them which be in Judea flee to the mountains.” Here we must remember that Judea would, in a greater sense, symbolically represent  Christendom. ​

Then let them which be in Judea flee,” evidently refers to more than the destruction of Jerusalem and the time of trouble which came upon that land in A.D. 70. Proof of this is furnished by comparing verse 21 with Danl. 12:1. This greatest time of trouble is at the close of the Gospel age unquestionably, though the closing features of the Jewish age were typical of it.​

To flee out of Judea (literal) to mountains is peculiar since Judea was in fact “a hill country,” and Jerusalem is described as set in the top of the mountains. Instead, apply mountains symbolically. The mountains represent God’s kingdom. Song of Solomon 8:14 refers to the Bride of Christ calling to her Beloved, Jesus, to come to her from the “mountains of spices”. ​

Thus we are to flee to Christ’s true kingdom through the merit of Jesus’ sacrifice. Ephesians 2:5-6 (NKJV), God “made us alive together with Christ (by grace you have been saved), and raised us up together, and made us sit together in the heavenly places in Christ Jesus.” ​

How? We do not support the Mass nor churches which conduct masses. We leave Christendom, repudiating her forms of godliness and worldly power. Jesus’ words prepare us for the spiritual flight and trials of these last days. His command to flee, and the description of its trials, connect with Revelation (18:4). “Come out of her, my people, so that you may have no fellowship with her sins, and that you may not receive of her plagues.” ​

2 Timothy 3:1-5, “in the last days perilous times will come: For men…having a form of godliness but denying its power. And from such people turn away!” 

Christian believers are to be sanctified and made holy through study, pray, service, and obedience. 1 Thessalonians 5:23, “Now may the God of peace Himself sanctify you completely; and may your whole spirit, soul, and body be preserved blameless at the coming of our Lord Jesus Christ.”
