Logos for December 14, 2019--The Observance of Christmas. What Is Christmas? CHRISTMAS is coming,” is the note that is sounded throughout our world from East to West and from North to South. With youth, those of mature age, and even the aged, it is a period of general rejoicing, of great gladness. But what is Christmas, that it should demand so much attention? This day has been made much of for centuries. It is accepted by the unbelieving world, and by the Christian world generally, as the day on which Christ was born.
