I’m not Catholic, but how does liturgy in a language you can understand, ruin it for you? If all you’re interested in is the syntax, cadence, and melodiousness of the service, you’re missing the point of the words themselves. Most of them are SCRIPTURE. Unless you understand the Latin, what’s the point? It would be like me listening to someone read the Bible in French. It may sound beautiful, but other than an appreciation of the beauty of the sound of the language, it would not benefit me in the least, Blasphemy in French would sound just as melodious to the ear.
I spent 10 years in Catholic parochial school. Many times a week we went to mass. It was a beautiful spiritual experience. As i did spend many years I knew what the words meant. The selection from the gospel and homily is in English.
I took two years of Latin in HS. But that was a near failure for me. Let’s just say I passed.
