It’s Sunday . . . the (REAL) first day of the week also known as the LORD’s day (Rev. 1:10). Monday is only the first day of the BUSINESS week. Think about it. Many calendars now show Monday in the first day of the week spot (far left) or at least allow that as an optional view (i.e., electronic versions). How secular we have become. And don’t forget C.E. (Common Era) and B.C.E. instead of B.C. and A.D. (Anno Domini; lit. year of our Lord).
