I have never heard of Divine Mercy Sunday. But then I have not been a Catholic very long. We always called the Sunday after Easter “Low Sunday.” I forget why. In the Episcopal church it included the Blessing of the Tartans, which was exciting if quite noisy.
“The Catholic Church teaches that it is a mortal sin to miss Mass on Sundays without a good reason.”
What would constitute a “good reason”? Other than being in the hospital, for example, or in a very small town in Rural Alabama where Baptist and Methodist were your only choices?
I will be posting about Divine Mercy Sunday soon. Hang tight! And blessings for a wonderful Easter celebration of the Resurrection!
Good reason is intentionally left a bit open for each person to discern. For example, being in an area where one has to travel is a good reason to some and not others.
As long as good reason is not “dumbed down” to a level of scandal one needs to trust their conscience and advice from their spiritual advisor.
I am pretty hard on myself for what is a “good reason” to miss mass, but would not have as high expectations for others.
