Christ is our one mediator/intercessor, yet, St. Paul commands all Christians to be intercessors/mediators. Then notice the first word in verse five: “For there is one God and one mediator…” And then in verse seven he says, “For this I was appointed a preacher and apostle.” What is an apostle if not a mediator?
Christ is our Mediator, not Paul. Paul didn't do a thing to make peace between us and God.
He could do it all—and all by himself—if he wanted to. He could come down here right now and write this post much more effectively than I ever could.
And do it without all the heresy, at that.
