You use the Bible and God as interchangeable.
Paul does not claim that God is speaking through him.
Paul is an evangelist.
Jesus as the messiah would be the next authority after God.
Paul doesn't claim that Jesus is speaking through him.
Mark 10:17-21
As Jesus started on his way, a man ran up to him and fell on his kees before him. "Good teacher," he asked, "what must I do to inherit eternal life?"
"Why do you call me good?" Jesus answered. "No one is good--except God alone. You know the commandments: Do not murder, do not commit adultery, do not steal, do not give false testimony, do not defraud, honor your father and mother."
"Teacher," he declared, "all these I have kept since I was a boy."
Jesus looked at him and loved him. "One thing you lack," he said. "Go, sell everything you have and give to the poor, and you will have treasure in heaven. Then come, follow me."
Jesus pretty much sumed it up.
The author of Matthew added: Love your neighbor as yourself.
So the question is:
Does Paul have the authority to change or add to what Jesus supposedly said?
If we do not follow Paul's interpretations or additions, do we truly miss the mark?
A gentle answer turns away wrath, But a harsh word stirs up anger.
