Knowing very well that there is no date specified in the Holy Scriptures, we celebrate the festival of Sun God of Roman empire as Christmas day.
The very simple reason is that we want to have fun, eat, drink and party in the winter. Christmas is the reason. Who bothers about our Lord today. We concentrate on Santa, gifts, decorating tree and crib.
If HE is born in our heart, then it is real Christmas.
Merry Christmas to you all.
