The Mass is well framed in the last chapter of Luke:
"their hearts were burning in their breasts as He explained Scripture to them"....and they asked Him to "remain with them" and He answered their request and ... "they recognized Him in the breaking of the bread."
The two parts of the Mass are the reading and explanation of the Scriptures (the Old Testament and/or the Epistles, the Psalms, and the Gospel), followed by words of Consecration and the Breaking of the Bread.
We recognize Him in the "breaking of the Bread" and the reception of his Body, Blood , Soul and Divinty in the Eucharist. In this way, by Word and Sacrament, He fulfills our desire for Him to "remain with us."
And up to this day, He does so, at all hours around all the world.
The 16th century LUZR's, (Luther, Ulrich Zwingli, and other Revolutionaries), dethroned Jesus and chased Him out of the Sanctuary.
Now, I have nothing against the progeny of the protestant progenitors. They are doing their level best to study Scripture and attend Sunday services and they try and follow Jesus.
However, not one in one million know the truth about the 16th century LUZR's.
Malachias 1 prophesies ...
For from the rising of the sun even to the going down, my name is great among the Gentiles, and in every place there is sacrifice, and there is offered to my name a clean oblation: for my name is great among the Gentiles, saith the Lord of hosts.
*But, the protestant revolutionaries falsified Scripture substituting incense for Sacrifice and pure offereing for oblation (and also heathen for gentile)
*It is clear they absolutely had no love for Scripture when it came to a Prophesy their ideology rejected. They simply falsified Scripture to cement their revolution which abandoned the Commands of Jesus vis a vis Worship.. Now, is there one in one hundred million well-intended protestant who knows this? NO. We must preach it to them.
We must preach this truth to them because they have been denied their birthright as Baptised Christians. As Baptised Christians, they ARE related,imperfectly, to the Church.
However, their worship is sans Sacrifice.
For Catholic and Orthodox, our Churches are permeated with the Odor of Sanctity because ours is not only the Worship Prophesied by Malachias, it is the Worship Malachias Prophesied and Perfected by Jesus and He Commanded His Apostles to Worship this way as The Way until the end of time.
At a Catholic Mass/Orthodox Divine Liturgy, it is the action of Jesus, as Priest, Victim, Meal, which is the focus and essence of Worship.
In a protestant service, it is solely the action of man - reading and commenting upon scripture and singing hymns and praising God. Now, there is nothing wrong with that. HOWEVER, there IS something wrong in that Our Lord and Saviour has been excised from the exercise. Protestants tells us the works of man are bloody rags. By their own words they are condemned. Their service is solely about the work of man (bloody rags)as the protestant progenitors jettisoned the Sacrifice, Priesthood, Eucharist and rejected Apostolic Succession, Eucharist, Mass etc.
What IS acceptable to God as Worship? Bloody Rags or the PluPerfect Sacrifice of the New Covenant?
They need to hear the truth. And I will preach it to them
