“Protestant Americans do not own the English language so deal with ...”
And if God inspired the Holy Scriptures in English instead of Hebrew, Aramaic and Greek, well, you might have an argument there. In this case, your point is interesting, but based on a false premise.
OK - where in Hebrew, Aramaic or Greek does the Bible say that one Christian can’t ask another Christian for something (i.e. pray in British English)? If you can’t find that verse then I can pray TO Mary.
