The RC’s are a little slippery on that point. They do make allowances that salvation is attainable through other churches, but they still claim they are the only truly reliable way, and that all the salvation you might find elsewhere still “flows through” them.
oneness pentecostal, That I am not familiar with (unless there is also another name)
I would include those formally Christian churches that went the way of “name it and claim it”, or “all paths lead to God” (sure you know who they are)
