The doctrine of the Holy Trinity, for example, is related to how we behave, and what we become. We don't have to all have the same beliefs about the Trinity or how Jesus is God and man. We just need fellowship in the Spirit. Such talk is nonsense. Then remember this.
Words carry reality.
Christ is somehow mystically within each of His commands. And anyone who receives the Logos through His commands, receives at the same time, through it, the Spirit, which is also naturally found in that command. Therefore, anyone who receives a command from Christ and does as commanded, has received the Holy Trinity. And, being modernists, they cannot conceive of happiness accompanied with pain. But the Scriptures teach us to rejoice in pain and suffering.
