Matthew wrote primarily to Palestinian Jews and used the language of fulfillment of Hebrew Scriptures. Paul addressed his letters to cosmopolitan, urban, Hellenized Jews. The circumstances and cultures of the writers affected the style and the content used to communicate the message of Jesus. Although we affirm diversity, and the early church did welcome Jew and Gentile, male and female, slave and free, church history has included conflict and division. Today, there continues to be division within the Body of Christ, based on issues of interpretation and authority of Scripture.
Some divisions reflect petty differences, but many are based on substantive issues.
These divisions led to the formation of thousands of Christian denominations and faith communities.
