Modern liturgists despise this image of Jesus Christ the High Priest because it exalts the "sign" of the ordained priest who in fact is a sacramental image of Jesus the High Priest during the Mass and orders the laity or the assembly (of which the ordained priest is also a member) to Jesus Christ who is their Head, Lord and Savior and to whom every knee shall bow and every tongue profess! What's wrong with modern liturgists? They are the reason why the Church's liturgy in the post-Vatican II era has undermined the mission and evangelization of the Church and reduced the number of men considering the priesthood thus depriving the Church of the Holy Eucharist in many places in the world!
Many liturgists of the progressive type (and keep in mind that liturgists tend to be control freaks and dogmatic about their theological perspective turning theology into infallible dogma) are "not nostalgic for what they regards as the repetitive nature of the old Mass, neither the exaltation of the celebrant to the detriment of the people of God; and they deplore the marked split between the priest and the assembly."
What these liturgists want is an egalitarian Church where there are no distinctions between clergy and laity and there is a blurring of the ministerial priesthood with the common baptismal priesthood of the laity and clergy together. They also want an egalitarian Jesus Christ, a buddy, a brother, a casual friend not Lord of lords and King of kings! They want Milquetoast Jesus that is symbolized in the image below.
The true sign of Holy Orders in the Holy Sacrifice of the Mass should never be diminished. No matter the form of the Mass Jesus Christ is to be exalted as Head of the Church, High Priest and Bridegroom to His Bride the Church. In the ancient form of the Mass, the priest himself is not exalted simply because he is a priest, but Jesus Christ, the High Priest is exalted the sacramental sign of the ordained priesthood! This is the sign of the Sacrament of Holy Orders especially during the Holy Sacrifice of the Mass that must be abundantly clear but for some reason is not as clear in the Ordinary Form and by design of those who promote their weak theology as dogma in this regard!
The fact that in the design of the Ordinary Form of the Mass liturgists purposely do not exalt Jesus Christ as Head of the Church, High Priest and Bridegroom obscures this most powerful sign of the liturgy within the sacramental sign of the person of the ordained man especially in the sacramental rites of the Church. This is a terrible aberration to say the least.
What has this led to in the post-Vatican II experience of the Liturgy and the life of the Church? A decline in vocations to the priesthood as well as scores of priests leaving the priesthood for the lay life of marriage and secular employment.
Why were there more men in the seminary prior to Vatican II and why has there been a recovery of interest in the priesthood since Pope St. John Paul II and Pope Benedict? Because there has been a recovery of the true nature and sign of the sacrament of Holy Orders and in continuity with the pre-Vatican II understanding of this sign not in rupture to it.
Will going back in time by liturgist to the day when there was not the hermeneutic of continuity; when the 1962 Roman Missal was thought a pariah of inequity, duplicity and repetition serve the Church well?
Of course not! “You cannot base your decisions on a past era where things were different...”
