My first exposure to the TLM was when I was a student at Holy Cross, and the super liberal “religious studies” professor who was teaching Church history took us on a field trip to Holy Trinity (German) Church in Boston for a solemn high Mass on the Feast of Christ the King. She presented it as “medieval liturgy.” I told a Trad priest this a few years later, and he got a chuckle. The only downside from the experience came later, when I looked up the celebrant from that Mass. It turned out he used to seduce teenaged girls when he was a young priest. Thankfully, my faith was well immune to that sort of thing by the time I learned of that.
