No matter how you dress it up, that's essentially what it boils down to and in spite of the fact that the RCC tried to weasel out of directly saying that with its pronouncements in Vatican II, it never really ever directly denied it. And the Catholics on this forum keep reinforcing what we keep saying, that the Catholic church teaches that those outside the church, who are not Roman Catholic, are going to hell.
Outside of the teachings of Jesus and the Church, we have no authority. You wanna take it up with Jesus, do so. It is outside of the realm of Christianity and you do so in unmapped territory. Who knows? You may find the Reformed limousines lined up ready to shuttle you in comfort to Heaven. But if you wish to stay true to sola scriptura, then you cannot, nay dare not for the sake of your soul, go beyond what is written on the pages of Scripture. You wish to stay sola, then do so. But at least be true to it.
I don't. That's why I don't accept the traditions of men and don't accept any church teaching that elevates such traditions to the level of Scripture as the Catholic church does.
The Catholic church teaches many things that are NOT supported by Scripture and considers its traditions to be on equal footing with Scripture itself.
