Jinggam

We have been fighting about "The Lord is come" and the historical context. M kept on saying it should be "has come" or "coming." I had this argument under my thumb because "Joy to the World" was written by Isaac Watts in the early 1700s and at that time "The Lord is come" was gramatically accepted. There was another version used by the Mormons which corrected it. So I won.
But then there was this Badjao children who came to us and sang "Jingle Bells" and none of the words matched. At least Jingam Bells has "bells." The Badjao version I heard has nothing right.
"Because it wasn't their culture to have Christmas," A said.
"It's more of them not given a chance to learn to read and write," was what I said.
