I’m not Catholic. Other than note my concern, there doesn’t seem a whole lot I can do.
But you have a stake in Catholicism, because you have a stake in Christ. Isn't that right? Look around you. When the Enemy targets Christianity, the bullseye is the Catholic Church.
"Other than note my concern, there doesn’t seem a whole lot I can do."
It seems to me there's always something you can do. (I am preaching to myself here as well. Good Lord, do I need a spur in the sides! -- Or a kick in the south end of a horse going north.)
You do believe in the Communion of Saints, e.g. intercessory prayer, don't you? Pray out loud for the ones under fire. Pray for the Pope --- he's gonna need it. It's a start. You call on God. Then God calls on you.
