I think the Holy Spirit is perfectly capable of protecting the Church from erroneous Popes.
The issue of communion for the divorced and remarried is tricky and technical; I know of a line of reasoning which would allow it, bit that is not what the Pope has put forth, nor has he adequately explained himself on this issue. I am not sure what wil come of this.
Perhaps you need to convince MOST of FR's Catholic of this!
Thje vast majority seem to want to heat up the oil and collect bundles of faggots!
So the state of the church is an example of the Holy Spirit protecting it?
Then why did He let this pope or any bad pope, get elected in the first place?
Doesn’t He guide the college of cardinals in the selection of the pope?
