Interesting problem they have here.
First, they need to decide if the Holy Spirit guided the CoC in selecting the pope in the first place.
If He didn’t then they did it contrary to the example in Scripture they like to appeal to in Acts, and the pope is merely the choice of men without God’s intervention. Which then complicates things by nullifying the claim that the Holy Spirit protects the church in the area of faith and morals.
If He did, the GOD is then repeosnible for PF and the mess he’s made. God has then given His approval to what’s going on and is allowing Francis to represent Him. Then the problem the Catholics have is that if they are fighting this God ordained pope, they are fighting God’s will for their church and being disobedient to Him by not submitting to God’s choice for them.

We've had one Roman Catholic on record saying NO.
OR, and from the evidence of centuries culminating in the current exposure, or the Catholiciism is as Paul perceived ‘another religion’, thus The God is not directing that ORG as a representative of HIS GRACE.
