That rubbish remark depends entirely on the strange notion that Benedict is unquestionably the Pope, which is absolutely not true.
He is a very questionable "pope", one that must be watched carefully.
I strongly suspect Benedict is an obstinate, manifest heretic. I don't believe I should say that as it isn't my place to do so. Attending the religious services of heretics, schismatics and infidels is a reprehensible moral evil, which the author of this blog completely fails to realize. He has no Sensus Catholica because he doesn't even find what Benedict has done to be questionable.
