What makes a Southern Baptist Southern?

This morning I was asked a question in the Bible study group I lead on Monday mornings- "What makes a Southern Baptist Southern?" I didn't think of this answer then, but a good answer-, No, it's not our love of fried chicken with all the fixins! It is a serious issue in light of the fact that many churches are eliminating all reference to their denominational heritage from their names. So, what makes a Baptist a Southern Baptist? Here is an outline of my answer-
1. A commitment to the authority, inerrancy, infallibility, sufficiency, and eternal nature of God's Word. The past 30 years Southern Baptists have fought a battle to reclaim this definition of the Bible. After decades of theological drift, Southern Baptists have anchored themselves to the Word of God.
2. A commitment to cooperatively reach the world with the gospel. Our Cooperative Program enables churches our size to have an impact in the world disproportionate to our size. By combining our gifts (currently we give a little more than 10% of our undesignated offerings to the Cooperative Program) with gifts from thousands of other churches we are able to have a direct link to over 10,000 missionaries across the world, to support the educational ministries of 6 seminaries, and to assist in the operation of an Ethics and Religious Liberty Commission that has a world-wide impact. That's a phenomenal opportunity for a church of under one hundred people!
3. An unwavering commitment to congregational church polity. That might be a fancy way to say, every church is autonomous and independent. Churches in our denominational heritage may be purpose driven, but they are most certainly congregationally driven. Decisions are made by the congregation- not the pastor, not a board of deacons, or trustee;s, but ultimately the individual church member is responsible for making decisions regarding the ministry of his or her local church.

I'm sure others might have answered differently, but from where I sit this seems to summarize why I am a Southern Baptist!
