Hey - nevermind. Google is my friend. Haven’t really paid much attention to what is going on inside the CC, but it is fascinating to me for some reason. Some interesting reading about Amoris Laetitia.
1) Francis is trying to change the doctrine of the Church. No pope is allowed to do that.
2) He wrote an ambiguous paragraph in a document that is being used to justify bad things, and has effectively killed the commandment "Thou shalt not commit adultery," as well as three of the seven sacraments of the Catholic Church (Confession, Holy Communion, and Matrimony).
3) Only a few cardinals are publically opposing him, along with a handful of bishops (out of the entire world).
4) Muller is the only person on earth with the authority to overrule the Pope on matters of doctrine, but he tried to play both sides of the fence and Francis and his friends have been free to do whatever they want.
Hope that helps as a quickie summary.
