One could of course respond by citing the innumerable multitudes of Protestant converts who returned to the Church before the existence of the Novus Ordo, most of them because of the radical difference between the Traditional Latin Mass and their own worship. For anyone who wants to read some examples of this, I highly recommend Joseph Pearce's book Literary Converts, which chronicles in fascinating detail the veritable army of English converts that entered the Church between 1850 and the Second Vatican Council.
But I also want to appeal to my own experience here, because I am among those who came into the Church through exposure to the Novus Ordo. It made me question to what degree the Novus Ordo itself was an aid in my conversion. Do I have the Novus Ordo to "thank" for being Catholic today?
I was baptized Catholic as an infant but never raised in the faith, by which I mean I was never taken to Mass, never made a First Communion, and so forth. I came to Christ when I was 19 through the evangelism of a Protestant friend of mine. My first real experience of Christianity was in the sphere of what I would call Protestant house-church Pentecostalism. I returned to the Catholic Church when I was 22 years old as a result of personal study and prayer. It would be laborious to catalog the various winding paths that led me to the Church, but I can sum them up in three points:
As I began my journey towards the Church, I began going to Mass. My first experience of the Mass was of course the Novus Ordo, as I didn't even know the Traditional Latin Mass was a thing. But more importantly, I did not understand that the Novus Ordo was not the historical Mass.
As I was studying the history of the Church, everything I was reading about was of course in the time of the traditional liturgy. When I read about St. Philip Neri going into ecstasy at Mass, it was the traditional Latin Mass. Or the Mass that St. Isaac Jogues offered in the wilderness, suffered, and died to bring to the Iroquois. Or any of the great stories from our heritage. It was always the traditional Latin Mass.
I certainly did not know any of this. Pre-conciliar texts of course did not know there was going to be a Novus Ordo in the future, and hence they did not refer to the Mass of the ages as the "traditional Latin Mass", but simply "the Mass", as they had no conception there would ever be any other. And post-Conciliar texts—anxious to stress continuity between the pre and post-Vatican II Church—simply spoke of the Novus Ordo as if it were essentially the same Mass the Church had always celebrated. Since pre-V2 texts were unaware of future rupture and post-V2 texts were eager to downplay rupture, the result was that I studied my way into the Church without ever realizing there was a rupture. I had no understanding that the Novus Ordo was not the traditional Mass.
But, upon reflection, all of the reasons I wanted to be Catholic in the first place were due to what I read about the pre-Conciliar Church. Consider this: I knew from my historical studies that the language of the Church was Latin. I loved this. I loved the idea of the universal Church having its own sacred, universal language that could breach the gap of culture and geography and undue the division of Babel in the sacred tongue of Latin. I actually went back to college and studied two semesters of Latin because I thought I would need it to be Catholic. I smile when I think of my naivete then, assuming the entire Church still used Latin! Silly me. But that was the impression I got from my historical studies.
There's many other examples—Gregorian chant, missionaries who actually wanted to make converts, popes who stood up to the trends of the world instead of embracing them, religious orders who wore traditional habits and were still faithful to their orders' charisms, a biblical exegesis that took the Scriptures seriously, architecture that reflected the glory of God instead of the ugliness of modernity, lots of pious devotions practiced at the parish level. Yes, I know I am leaving out the biggest thing, that is, the Mass of the ages. But keep in mind, I was not yet aware that the new Mass and old Mass were different.
At any rate, the simple point is this: the Church I read myself in to was the pre-Conciliar Church.
And as an aside, have you ever noticed that many classical Protestant objections to Catholicism also all presume the pre-Conciliar Church? Like, objections about Marian veneration, use of Latin to "keep people from reading the Bible", belief in the Real Presence, veneration of statues, etc. Following historical precedent, today's Protestants generally attack a Church that no longer exists. They expend so much effort attacking the veneration of statues which the vast majority of parishes removed or relegated to mere decoration. They publish long, impassioned rebuttals to belief in the Real Presence—a belief that 69% of Catholics no longer hold. It seems to be the case that, just as I read myself into a pre-Conciliar Church, so do Protestants attack a pre-Conciliar Church. Either the NuChurch does not threaten them, or perhaps, being outsiders, they are simply unaware of how much things have changed in our household. Who knows.
Now, when I actually got into the Catholic Mass and started experiencing the Novus Ordo, it did actually move me deeply. But the reason it impressed itself upon me was not anything particular to the Novus Ordo, but merely the fact that there was a liturgy at all. Coming from a Pentecostal background, the mere existence of a structured liturgy, liturgical year, fixed readings, a Eucharistic rite, etc. were deeply impressive. But upon reflection, what impressed me most was just liturgy qua liturgy, not anything special about the Novus Ordo.
After I got into the Church, I obviously noticed the dearth of Latin immediately. And the absence of chant. And bad music. And many other things that we associate with what is loosely called "Novus Ordoism" these days. This was disappointing, but at the time I thought this state of affairs was peculiar to my parish. Eventually I found a parish that did what I called a "reverent Novus Ordo" and I thought things were fine.
As happens with many converts, it was only when I started to realize how little the current rite resembles the old rite than my mind changed. After I had been Catholic for five years, I of course had learned about the Second Vatican Council and the Novus Ordo and everything, but I assumed that the Novus Ordo was basically the same as the Traditional Latin Mass. I assumed that perhaps 90% was the same and the changes only superficial. Crazy, I know! But, in my defense, this was pre-Summorum Pontificum, and I had very little opportunity of ever actually experiencing a traditional Mass for myself. And, as I mentioned above, every piece of contemporary literature on the subject—generally from the Catholic Answers-New Springtime-EWTN quadrant of Catholic intelligentsia—stressed pre and post-V2 continuity. It was stressed to a degree that, in retrospect, I now find ridiculous at best and deceptive at worst. But the end result was that I was ignorant of the true depth and breadth of the rupture.
Eventually I met another Catholic, just a DRE at the time but now the eminent Dr. John Joy, who gave me copies of Klaus Gamber's The Reform of the Roman Liturgy and Michael Davies' Liturgical Timebombs. These books finally opened my eyes to how much had actually been gutted from the Tradition. How the prayers were changed. The calendar. The sacraments. Literally everything. The Pauline Reform was not a cosmetic make-over. It was almost an entirely new edifice.
Around that time I also got a hold of the actual day books of the Second Vatican Council. The day books were essentially the daily logs of the day-by-day proceedings of the Council: what bishops spoke on what days, the subjects they spoke about, the exact vote tallies on the different proposals and documents, and so forth. In reading these, I was astonished by the way the liberal faction had dominated the procedures of the Council. I couldn't believe the unplugging of Cardinal Ottaviani's microphone during his speech actually happened. And many other instances of chicanery. Yet there it all was. This led me to Ralph Wiltgen's The Rhine Flows Into the Tiber, which helped make sense of what I had read in Council day books and pulled the entire history of the Council together in a cohesive narrative.
At a certain point, it dawned on me that the sad state of affairs I had lamented in some of my local parishes was not confined to to those parishes. It was, in fact, the state of the Church globally. This was an incredibly depressing realization, but it ultimately led me to the study of the Traditional Latin Mass, which at that time was still only offered under the Indult. When I was able to compare the prayers of the TLM to the Novus Ordo, the difference was night and day. "Why wouldn't anyone want to pray like this?" I thought to myself in astonishment at the obvious superiority of the old prayers.
The curtain finally fell when I had the following realizations:
(1) The Church I had fallen in love with through study was the traditional Church, which for all intents and purposes no longer existed.
(2) Whatever it was that had replaced the traditional Church was not only different, but also inferior to it in every way. Those things I liked about the contemporary Church were precisely those facets of traditional Catholicism that had survived despite the rupture of the Conciliar era.
(3) Finally, this displacement of tradition was not some accident of history, but was a very deliberate act of erasure—of intentional cultural warfare waged against the Church by one of her own factions.
The Church I had read my way into simply did not exist. It's hard to explain the degree of frustration I felt. Not just frustration, but, a sense of having been robbed. Yes, robbed; for to intentionally cut off the great stream Tradition is to commit the sin of theft against future generations, who are thereby deprived unjustly of a heritage they ought to have inherited. Destroying tradition is to commit theft against future Catholics.
Was the Novus Ordo responsible for bringing me back to the Church? Only in an indirect way, in the sense that I found a few scattered remnants of tradition within the contemporary Church that nourished me enough to secure me in the faith. I do not therefore think the Novus Ordo is a good "transitionary" Mass for people who were in my situation. The fact that God used it to my advantage does not mean it would be to the Church's advantage in general. To use another example, I came into the Catholic Church through the bridge of Pentecostal Protestantism. Pentecostalism was the step God used to bring me to the Catholicism, which was a good thing. But that God used Pentecostalism for my good does not mean I view Pentecostalism as an objective good that I would recommend.
God can bring good out of anything, but it does not follow that those things are goods.
