The only thing patently laughable is someone posting claiming to be a “catholic” who clearly has no idea of what catholic beliefs are. Normally I would suspect the person is not a catholic at all, after all how could someone have such ignorance of the faith they claim to hold, but sadly I have met so many ignorant “Catholics” that nothing surprises me anymore.
Absolute nonsense.
Being a Catholic does not mean you march in lockstep like a mindless drone.
The concept of papal infallibility was developed in the 19th Century by Pope Pius IX.
