I think you’re right there I do remember that teaching from long ago, I think when I was a child. But it’s strange because this morning EWTN had the Luminous Mysteries with the Rosary with Mother Angelica.
I think they are just re-run based on day of the week and they haven’t taken Lent into consideration.
Mother Angelica has not done any live programs for a number of years now. She is 90 (I believe) and had a very bad stroke a few years ago.
