Care to give any sort of citation, link, or anything like that?
Or did you just do a cut-and-paste job from some anti-Catholic screed?
The Pope has no authority to modify or abrogate Divine Law. Ever. Sorry, but that's the way it is.
The anti-Catholic screed I cut & pasted this from is "Prompta Bibliotheca canonica, juridica, moralis, theologica, necnon ascetica, polemica, rubricistica, historica", by Lucius Ferrarisa. The "Catholic Encyclopedia" lists him as an eighteenth-century canonist of the Franciscan Order. The exact dates of his birth and death are unknown, but he was born at Solero, near Alessandria in Northern Italy. He was also professor, provincial of his order, and consultor of the Holy Office. His work has went through several editions and the Encyclopedia remarks that it is "which will ever remain a precious mine of information..." I found it so!!
