The Pope's perspective is not subjective because God has ordered reality according to His law and anything which contravenes that law is disordered. That law is objective reality.

Your reply:

I'm not sure about that last part. Don't religious scholars disagree on what God's law is?

Yes they do. But we're talking about the Pope, the Vicar of Christ.. Not just some religious scholar. On Faith and Morals he's speaking with the guidance of the Holy Ghost. And it's infallible.

Religious scholars may have any number of opinions. And they are just that, opinions. When the Pope speaks excathedra on these issues it's no longer an opinion. It's truth.

Well, isn't that the whole debate? As a Catholic, that is your position. However, no other religion accepts that claim (AFAIK).

The Catholic claim that the Pope speaks with the guidance of the Holy Ghost is only persuasive to Catholics.

When the Pope speaks excathedra on these issues it's no longer an opinion. It's truth.

For Catholics, sure.
