KoanTao, the church might have taken aspects from a Pagan holiday's for Christmas so it was easier for the Pagan people to adapt to Christianity, but that doesn't have anything to do with the songmeaning here, it's a great song, about the true meaning of Christmas (or i guess the birth of Christ if u're going to get specific since as you already pointed out, most likely Christ was born in the summer and we just adapted Christmas to a Pagan holiday)
