This is so wrought with error I scarcely know where to begin.
First, it is a blog site, not a Catholic site. The blogger is anonymous. So your information is an anonymous source by a biased blogger on the internet, who states, “A Filial Appeal signed by 790, 190 Catholics, including 201 cardinals…”
The link is the internet petition. I can’t say this enough. Do not believe everything on the internet. When I saw that one commercial where the guy said they couldn’t put it on the internet if it wasn’t true, I thought it was hilarious that someone could be so stupid. Every day I am proven it was all too prophetic.
The link reports this petition as 35,361 petitions world wide, not 790,190.
The petition has nothing to do with Amoris Laetitia, but was in response to the first draft of the first synod documents.
There is no verification of a single person who signed it.
The petition is not only about upholding the doctrine of the Church but also says, “…and to Her uninterrupted discipline, as received from the Apostles.” A faithful Catholic must accept changes in discipline, or he is not a faithful Catholic.
The only thing I have learned from this is that this onepeterfive place is one more that is not to be trusted. We must listen to God, who speaks through His word and through His body on Church. Listening to bloggers and conspiracy weavers and allowing them to shout down what God has established on Earth is just setting up of false idols to serve as our gods.
