Hi Timothysis.
Your comment raises some interesting questions.
How do we explain the fact that Islam is even more strict about using a non-native language, that Islam is growing, and that its adherents seem to have at least as good an understanding of its tenets as most Christians?
How do we explain the fact that in prior times, most Catholics could identify the Blessed Sacrament as the body of Christ? Certainly, they prayed the rosary, the angelus, and vespers in Latin, and understood most of what they prayed.
Perhaps the argument you are making is that modern people in the West are just too busy to learn another language. While this would be a compelling argument, it would leave open the question how Europeans and westernized orientals come to master foreign languages in greater numbers than Americans do. Is it education? Do we get a free ride if we fail to teach Latin so people can pray with the Church? Is it a sin against charity?
Last, to what extent does using a native language impede considered reflection. We all have had the experience of being on a telephone call while otherwise occupied; the experience is somewhat like the conversation between Wol and Winnie the Pooh when Pooh says, “Yes, yes,” and “Oh, no,” more or less automatically, without really listening to what Wol is saying.
How often at English services do we pray, without reflecting on what the words mean?
