I was an admirer of JP II and his Encyclicals. Still, it seemed to me an odd thing to do. Not wrong, but odd. And I don’t think it has done anything to increase the saying of the Rosary, which probably was his purpose.Well put, and I tend to agree. However, we do recite the Luminous Mysteries, regardless. Now, if I only could remember all of them without looking... :)
I do think the reason the luminous mysteries were added is because to cover the most important events in the life/teachings of Christ.
