Paul writes to Titus,
Paul is saying that Jewish people are spreading lies regarding the faith. These Jewish men rely on Old Testament prophecies"Jewish fables" and the law."commandments of men" Oddly enough, these are both things that Paul himself does not care for. (If he did, he would use them as examples in his writings, rather than dismiss them by saying things like "the law is done with.")
Let us suppose for a second that Paul is correct. There are some Jews who are coming around, not preaching that Jesus raised the standard of the law(Matthew 5:20.) or fulfilled it,(Matthew 5:18) but saying that it is needful to go back to the law of Moses.
Why is Paul saying this? Jesus said,
In fact, when the apostles stopped someone they thought was in the wrong, this happened:
Jesus said to love your enemies, so what he instructed his disciples to do regarding that situation is exactly the same thing we should do, whether it is a friend or foe.
Value of this Evidence
This is fantastic evidence against Paul's case for apostleship. Paul originally sought to shut up the early believers. After his Damascus experience, he still had that evil spirit of forcing other to shut up within him. This goes against what Jesus said, "love your enemies."
