Scriptural anarchists apply St. Paul’s writings when it suits them, but then ignore passages like 1 Corinthians 12:25
That there should be no schism in the body; but that the members should have the same care one for another.
Their ancestors transgressed against this passage.
There is no doubt though that salvation outside the bounds of the visible Church on account of invincible ignorance.
But any Protestant who is saved will be save through the Catholic Church.
What if God doesnt see the RCC as part of the body and used Luther to begin to put the truth back out there? If the RCC is not part of the body there is no schism. What if God knows that the RCC is really the whore of Babylon and took His true body out of the RCC?
Not even the Catholic Church believes that anymore. Didn't you read any of the Vat II pronouncements?
Here's how it really should be said: All those who are saved are saved through faith in the shed blood of Jesus Christ. When they believe, they BECOME part of the universal church, the Body of Christ. So, no, no one is saved through the Catholic Church. The Catholic Church cannot save anyone, only Christ can do so, and he saves by grace through faith in him.
