2 Corinthians 10

8 Paul had nothing to be ashamed of, but his opponents should have been ashamed for fragmenting the church.
11 Paul insists that he is consistent.
12 Paul's opponents are guilty of relativism. However, God is not relative. He is the absolute.
15 Paul's opponents were not opening new territory with the Good News of Jesus. Instead, they were destroying what Paul (and others) had already built.
