It appears the author believes no decoration, or celebration should occur until after advent. It is wise to consider advent a time for preparation rather than celebration but I believe such a cut and dried, dogmatic approach is not the proper way to judge. In fact it seems the Friar has more trouble with the manner in which people celebrate, by esteeming the festivities themselves higher than the reason to be festive; the rushing of Christmas being only a symptom.
Is this why my parents would never put up the Christmas tree until Christmas Eve day?
As a family, we would always gather around and decorate the tree on Christmas Eve, before going to church. We were Episcopalian, not Roman Catholic.
And, the tree had to be taken down on New Year’s Day, with all the family helping. It was our tradition, but my parents never explained why they chose to do it this way.
