I'm going to have to disagree with you. Based on scripture and 2000 years of history. Jesus' bride/body is his Church which Ignatius is recorded as calling Catholic in 100 AD. The Church Temporally and eternally is the Kingdom that Jesus established. And Catholics are saved by Grace and a few of the other denominations who obey Jesus Christ will be saved by Grace that Christ gives through his Church. Ie Protestants wouldn't even have faith in Jesus Christ if not for the Catholic Church preserving the faith and the scriptures for 1500 years.
God grants the saving faith by his own intiative, NOT mediated through the RCC!
church again of Gos is the Body of Christ, those who have been saved, NOT the RCC, or any other earth bound/based organization!
Eraly church was NOT what we call today as the RCC, that which is called RCC was Apostated of from the groups that taught true Christianity!
The Lord revelaed the doctrines of faith/salvation to the reformers from his word, so even IF RCC was not around, would have still had that restablished in church!
