Galatians: Language

1. If anyone dares to disagree with Paul on religious matters, "let him be accursed." 1:8-9
2. Paul calls the Galatians "foolish" and thus makes himself worthy of hell fire. (Mt 5:22) 3:1
3. "I would they were even cut off which trouble you." Gosh, that doesn't sound very nice. But I wonder what Paul meant by "cut off". The New Revised Standard Version translates this verse as: "I wish those who unsettle you would castrate themselves!" 5:12
