When Pope Benedict XVI issued Summorum Pontificum, there was true and palpable excitement, almost like liberation from an oppressive ideology or foreign power that had invaded and overtaken the Church since Vatican II as it concerns the liturgy.
Immediately, after SP was issued, there was joy, video memes of exhilaration about the Traditional Latin Mass and its other liturgical celebrations released from the dungeon of a Vatican basement to breathe new life into the Church’s liturgical culture. It was a true experience of moving on, going forward and letting go of looking backwards at all the liturgical chaos of the post-Vatican II upheaval.
That all came to an end with TC. We returned to the liturgical wars of the past 50 years. We returned to the oppressive spirit of those days where every novelty was embraced and any hint of tradition associated with the pre-Vatican II Church was condemned.
But shortly after TC, Pope Francis issued his own liturgical document Desiderio Desideravi. The portion I post below shows the “I” spirit that the pope then condemns as gnostic, meaning the use of what “I” want rather than “we”. But count the number of times Pope Francis uses the word “I” as he communicates what he wants. This is a study in psychology to say the least!
Here’s a portion of that document. Press the title for the full Apostolic Letter. Have you experienced in your own parish any hint of the application of this document to everyday liturgical life with the excitement and joy that SP had generated?
TO THE BISHOPS, PRIESTS AND DEACONS,
TO CONSECRATED MEN AND WOMEN
AND TO THE LAY FAITHFUL
ON THE LITURGICAL FORMATION
OF THE PEOPLE OF GOD
hoc Pascha manducare vobiscum,
antequam patiar (Lk 22:15)
1. My dearest brothers and sisters,
with this letter I desire to reach you all – after having written already only to the bishops after the publication of the Motu Proprio Traditionis custodes – and I write to share with you some reflections on the liturgy, a dimension fundamental for the life of the Church. The theme is vast and always deserves an attentive consideration in every one of its aspects. Even so, with this letter I do not intend to treat the question in an exhaustive way. I simply desire to offer some prompts or cues for reflections that can aid in the contemplation of the beauty and truth of Christian celebration.
The Liturgy: antidote for the poison of spiritual worldliness
17. On different occasions I have warned against a dangerous temptation for the life of the Church, which I called “spiritual worldliness.” I spoke about this at length in the exhortation Evangelii gaudium (nn. 93-97), pinpointing Gnosticism and neo-Pelagianism as two versions connected between themselves that feed this spiritual worldliness.
The first shrinks Christian faith into a subjectivism that “ultimately keeps one imprisoned in his or her own thoughts and feelings.” (EG 94) The second cancels out the role of grace and “leads instead to a narcissistic and authoritarian elitism, whereby instead of evangelizing, one analyses and classifies others, and instead of opening the door to grace, one exhausts his or her energies in inspecting and verifying.” (EG 94)
These distorted forms of Christianity can have disastrous consequences for the life of the Church.
18. From what I have recalled above it is clear that the Liturgy is, by its very nature, the most effective antidote against these poisons. Obviously, I am speaking of the Liturgy in its theological sense and certainly not, as Pius XII already affirmed, Liturgy as decorative ceremonies or a mere sum total of laws and precepts that govern the cult. 
19. If Gnosticism intoxicates us with the poison of subjectivism, the liturgical celebration frees us from the prison of a self-referencing nourished by one’s own reasoning and one’s own feeling. The action of the celebration does not belong to the individual but to the Christ-Church, to the totality of the faithful united in Christ. The liturgy does not say “I” but “we,” and any limitation on the breadth of this “we” is always demonic. The Liturgy does not leave us alone to search out an individual supposed knowledge of the mystery of God. Rather, it takes us by the hand, together, as an assembly, to lead us deep within the mystery that the Word and the sacramental signs reveal to us. And it does this, consistent with all action of God, following the way of the Incarnation, that is, by means of the symbolic language of the body, which extends to things in space and time.
20. If neo-Pelagianism intoxicates us with the presumption of a salvation earned through our own efforts, the liturgical celebration purifies us, proclaiming the gratuity of the gift of salvation received in faith. Participating in the Eucharistic sacrifice is not our own achievement, as if because of it we could boast before God or before our brothers and sisters. The beginning of every celebration reminds me who I am, asking me to confess my sin and inviting me to implore the Blessed Mary ever virgin, the angels and saints and all my brothers and sisters to pray for me to the Lord our God. Certainly, we are not worthy to enter his house; we need a word of his to be saved. (cf. Ma 8:8) We have no other boast but the cross of our Lord Jesus Christ. (cf. Gal 6:14) The Liturgy has nothing to do with an ascetical moralism. It is the gift of the Paschal Mysteryof the Lord which, received with docility, makes our life new. The cenacle is not entered except through the power of attraction of his desire to eat the Passover with us: Desiderio desideravi hoc Pascha manducare vobiscum, antequam patiar (Lk 22:15).
Rediscovering daily the beauty of the truth of the Christian celebration
21. But we must be careful: for the antidote of the Liturgy to be effective, we are required every day to rediscover the beauty of the truth of the Christian celebration. I refer once again to the theological sense, as n. 7 of Sacrosanctum Concilium so beautifully describes it: the Liturgy is the priesthood of Christ, revealed to us and given in his Paschal Mystery, rendered present and active by means of signs addressed to the senses (water, oil, bread, wine, gestures, words), so that the Spirit, plunging us into the paschal mystery, might transform every dimension of our life, conforming us more and more to Christ.
22. The continual rediscovery of the beauty of the Liturgy is not the search for a ritual aesthetic which is content by only a careful exterior observance of a rite or is satisfied by a scrupulous observance of the rubrics. Obviously, what I am saying here does not wish in any way to approve the opposite attitude, which confuses simplicity with a careless banality, or what is essential with an ignorant superficiality, or the concreteness of ritual action with an exasperating practical functionalism.
23. Let us be clear here: every aspect of the celebration must be carefully tended to (space, time, gestures, words, objects, vestments, song, music…) and every rubric must be observed. Such attention would be enough to prevent robbing from the assembly what is owed to it; namely, the paschal mystery celebrated according to the ritual that the Church sets down. But even if the quality and the proper action of the celebration were guaranteed, that would not be enough to make our participation full.
