Let"s look at the facts. Christmas is, for God"s sakes- A religious holiday- the various religious Christmas songs- Silent Night- Adestes Fidelis, O Holy Night, etc are designed for ecclesiastical use and were originally written in Latin based languages ( O Holy Night was originally written in French- it translates too easily into that tongue!) OKay Silent Night was German or Austrian but is religious. the basic religious carols are in effect cosmopolitan and have found their way into the Hymnals. Oddly some artificial Spanish Christmas songs ( Mamacita- Santa Claus)- (Feliz Navidad) are artificial commercial jobs not native Spanish songs.
