Is God a mystery? Or has he given us knowledge and understanding with respect to His identity? The mystery of the trinity is the central doctrine of the catholic church. Knowing God is not a mystery is eternal life. People perish for lack of knowledge of God.
There are two sides in this conflict. The world has been drawn into worship of the creature, creation, beast. And in their forehead is written the name of what they worship, and their mother Babylon.
But God’s people have His name in their forehead, and the name of the mother of us all. Jerusalem above. The light on this issue is made clear in this study.
