I love the fact that while Christmas for the world ends on Christmas Day (just take note of how many folks take down their trees and turn off their lights starting today), for the Church Christmas is just beginning. We get to celebrate this wonder for 12 days (and Easter for 50)! The Church’s wisdom with the formation of the Church Year is truly evident here in this.
I especially appreciate this as a pastor. As a pastor, the days leading up to Christmas are so busy with the preparations to be made in leading the faithful in the services, that were Christmas to end on the 25th, I (we!) would miss it. But no, the Church continues to celebrate, and we pastors get to sit quietly and reflect on the wonder.
