I too was not entirely “moved” the first time I attended the TLM, although I appreciated it. Looking back, I probably wasn’t completely moved the second time either. It took a while. Now I’m a regular. I agree with Eagle that High Mass is much richer than the Low Mass.
While I agree with people who say the TLM is “the most beautiful thing this side of heaven,” one who hears this and attends for the first time may expect perfection itself, or to see choirs of angels in front of the altar. Sadly, there is no perfection on this earth. There will always be some forms of irreverence and boredom at any mass, anywhere. To expect otherwise is unrealistic.
I hope you give the TLM another chance or chances. God Bless!
