The Great Fifty Days have been termed a “Week of weeks”; with this first week (”Bright Week”) corresponding to Sunday.
So we are quite literally within a “week of Sundays”.
Interestingly, the Sixth Week of Eastertide (Rogate) corresponds to Friday in the Week of weeks. Every Friday is a commemoration of the departure of Our Lord to the dead; and so it is that during this great Friday week we celebrate His final bodily departure through the Feast of the Ascension.
Today at our church we lit all the candles just as though it were Sunday. I’ve never heard the term “Bright Week.” But it fits!
