From a PCG member:
We could or cannot know or understand the truth without God revealing it through Mr. Herbert W Armstrong and Mr. Gerald Flurry. That is the government of God. We have to follow them. We don’t have to focus about the physical things that are happening in the church(we don’t have to focus about people’s sins in the church but to pray for them to stop it) but we focus on the spiritual things God is given to us in the church through Mr. Gerald Flurry. It is only the PCG that is administering God government on this earth. And God is using only PCG to do His work on this earth.
