When the Catholic church starts actually taking action on its pro-abortion members instead of just talk and threats, then they can be taken seriously.
As long as they do not exercise church discipline for pro-abortion members, and the occasional bishop chastising the occasional politician is not serious.
It’s optics.
As long as Romanism doesn’t excommunicate or deny members communion for pro-sin stands, they become complicit in the sin.
Indeed, and complicity is the case with us all when we fail to do what we should. TradCaths will pronounced Teddy K Catholics as excommunicated, but that is not up to them, but a judging such begins with the local ordinary and can extend all the way to the pope. Whose leadership is the one that is to be followed in Catholicism, but even Ratzinger affirmed bloody proabortion, prohomosexual Teddy K.
TradCaths who rebel against leadership based upon their judgment of what valid church teaching is are essentially acting as Protestants in so doing.
