I’m puzzled as to how anyone can see it any other way. Where do they get that from?
From the organizations they belong to. Most just apply what that organization gives them to scripture rather than “searching scripture daily to see if what they say is true”. I grew up in one of those organizations. Always had questions they didn’t seem to be able to answer that matched what scripture said. That got be doubtful about what they taught and I began a lifelong investigation of scripture with prayer to the Holy Spirit for guidance and understanding. It didn’t take long to realize that the organizations that had there start in the RCC were only slightly less in error than the RCC itself.
If people only rely on what those organizations teach they are going to be rudely awakened one day soon.
