Hebrews 10:19-20 is dramatic: "Fulfillment of the Old Testament (especially the Feast of Tabernacles). It is the Catholic Eucharist — the only 'true new and living way.'"
Christ's crucified flesh on the cross rips apart the veil of the Old Testament tabernacle to give us "eternal" access to Most Holy Triune God through Holy Communion. Before, only one high priest could enter the most holy of holies once a year. Now a true Eucharistic — believing Catholic has access forever. Every second, there are five additional Masses in the world (over 500,000 daily).
Ever since Mary (mother of the church) knelt before the cross, there was a sacrificial Mass. Quoting Daniel, so-called scholastics emphasize the antichrist desecrating Jewish temple animal sacrifices. As Satanists have blatantly demonstrated, the "fulfilled" temple devotion the enemy seeks to destroy (the "eternal" sacrificial Mass of Malachi 1:11). Control: People, climate, even time — "eternality."
St. Alphonsus Liquori (doctor of the church) in holy perseverance" serves notice: You can't destroy the "eternality of the Mass; it will go underground as in communist China. More importantly, it has been and is forever worshipped in heaven by the Community of Saints — the focus being toward the alter, tabernacle and crucifix as one, Jesus Christ Himself (as in the Latin Tridentine Mass)."
The Eucharist ("Thanksgiving") fulfills the feast of the tabernacles whereby the Israelites gave thanksgiving for the harvest and ark of the covenant residing in the holy or holies.
Now Christ dwells in Holy Communion (John 6). And John 7:8 elevates our understanding of concluding Zechariah: Jesus would not attend the feast of tabernacles with others; only later did He attend privately. His time had not yet come on the cross. He is our feast of tabernacles in the Catholic Eucharist (with confession) — the "harvest of souls" (John 7:37).
The cross is the acme or zenith of our faith, the hinge that opens the door to the Last Supper preceding it and the Resurrection which follows.
Thus saith the Lord God. The bud blossoms into a rose.
