That doesn’t matter, because the pope, who led the anti-Semitism of the Catholic Church is infallible. But Luther was just an anti-Semitic apostate. The whole anti-Semitic issue is ridiculous on both sides, as both sides *were* guilty of it and both sides have denounced those previous behaviors. And as pointed out up thread the muslims, homosexual and liberals are pounding at the gate while free person argue about why their version of Christ is the only one that is correct and everyone else is going to Hell.
The ultimate mission of Christians isn’t political victory, though, but sharing the Gospel and making disciples of Jesus Christ. And on that, the Roman Catholic Church isn’t a partner. It holds many unchristian beliefs. Ultimately, those beliefs are actually contributing to the destruction of cultural and political Christianity (I come from an 80% Catholic city in the Northeast and it’s been “post-Christian” for decades), and means the Catholic Church won’t be able to defend biblical morality because it’s built on the wrong foundation. Should we abandon preaching sound doctrine for political cooperation then? No, that’s not the answer, and Christians will not be silent because the Holy Spirit compels us to speak God’s Word. You mention liberals, homosexual activists and Muslims. Those in the U.S. heavily tend to vote Democrat, but it doesn’t mean they’re laying down their differences. Evangelicals can and absolutely should cooperate with Catholics without being quiet about the many errant beliefs of the Catholic Church. That is spiritual health.
