Priests used to publicly describe Holy Mass as a Holy Holocaust

I still have this quote from Pope St Leo in a book about The Mass by Rev. Father Lucas  S.J.

....Now in a sentence which has been embodied in one of the prayers in the Roman Missal (the Secreta of the Seventh Sunday after Pentecost), St. Leo tells us that in His one sacrifice Our Lord has united and consummated the ancient rites with all their diversities. And indeed it is easy to see that His offering of Himself was a holocaust by reason of its completeness ; a propitiatory offering for sin by reason of its atoning efficacy and purpose, and finally a peace-offering whereby the atonement was not only made but sealed by a sacrificial meal. 

I'm still trying to get Popes, Prelates and Priests to return to the practice of referring to the Holy Sacrifice of the Mass as also The Holy Holocaust as some Fathers did publicly at the beginning of Vatcan Two.

Vatican Two opens and some Council Fathers make a public statement;

We wish to convey to all men and to all nations the message of salvation, love and peace which Jesus Christ, Son of the living God, brought to the world and entrusted to the Church.

In fact, it is for this reason that we, the successors of the apostles, all united in prayer with Mary, the Mother of Jesus, forming one single apostolic body whose head is the successor of Peter, are gathered here at the invitation of His Holiness Pope John XXIII.

Under the guidance of the Holy Spirit, we intend in this meeting to seek the most effective ways of renewing ourselves and of becoming increasingly more faithful witnesses of the Gospel of Christ.

We will strive to propose to the men of our times the truth of God in its entirety and purity so that they may understand it and accept it freely.

Conscious of our duties as pastors, we wish deeply to meet the demands of those who seek God “and perhaps grope after him and find him though he is not far from any one of us” (Acts 17: 27).

Faithful, therefore, to the mandate of Christ, who offered Himself as (a) holocaust “in order that he might present to himself the Church in all her glory …

Probably owing to ecumenism, the document on the Mass did not reference that unique description  (making it the singular possession of the Catholic Church alone) and after the closing of the council, according to Prof  Dr. Norman Finklestein; Finkelstein’s focus on 1967 as the creation date of the industry

the Jews made the word theirs and now there is not a Priest alive who would publicly refer to the Pluperfect Self Sacrifice of Jesus on Calvary as a Holocaust (If they know it is a holocaust) as Priests did publicly at the beginning of Vatican Two.

That is unbelievably tragic for if one were to ask any living Catholic today- "What is the Holocaust?" - less that .01% would say something like "It is the action of Jesus on Calvary where His burning love for mankind substituted for the fires of the OT Holocausts and it is His action that He actualises in His Priesthood in every single Mass celebrated on earth at any moment." but would say "O, it is what happened to the Jews in World War Two."

Shameful; what a loss
