"That's not a very nice thing to say about the Luminous Mysteries"
How judgmental of you!
Then again, is there anything "nice" to say about tampering with the Rosary? Annibale Bugnini tried to change the Rosary but Pope Paul IV stopped him, and sent him packing...
I like the "O my Jesus" prayer from Fatima. That's "tampering", I suppose, although it's heavenly tampering ;)
As for the Luminous Mysteries, the jury's still out, I guess... The normal mysteries were fine, if you ask me. But I don't run the Church.
