Quotes
Paul was the first corrupter of the doctrines of Jesus - Thomas Jefferson

Paul created a theology of which none but the vaguest warrants can be found in the words of Christ. Fundamentalism is the triumph of Paul over Christ
- Will Durant

Where possible, Paul avoids quoting the teaching of Jesus, in fact even mentioning it. If we had to rely on Paul, we should not know that Jesus taught in parables, had delivered the sermon on the mount and had taught his disciples the 'Our Father.' Even when they are specially relevant, Paul passes over the words of the Lord - Albert Schweitzer

Paul substituted 'faith in Christ' for the 'Christ-like life.' - Walter Kaufmann

If Christianity needed an Anti-Christ, they needed look no further than Paul
(Paraphrased) - Jeremy Bentham

Paul's words are not the words of God. They are the words of Paul - a vast difference. - Bishop John S Spong, Episcopal Bishop of Newark

My long-time view about Christianity is that it represents an amalgam of two seemingly immiscible parts - the religion of Jesus and the religion of Paul. Thomas Jefferson attempted to exercise the Pauline parts of the New Testament. There wasn't much left when he was done, but it was an inspiring document. - Carl Sagan

You can argue with the Book if you want.
