Are Calvinists Better Evangelists?

I want to extrapolate on a conversation underway on TFTG. Dr. Dever asks Dr. Duncan if Calvinists are better evangelists based on these statistics:

14.8% decline in the United Church of Christ

11.6% decline in the PCUSA

6.7% decline in the United Methodist Church

5.7% decline in the American Baptist Churches

5.3% decline in the Episcopal Church

5% growth in the Southern Baptist Convention

18.5% growth in the Assemblies of God

21.8% growth in the Christian and Missionary Alliance

40.2% growth in the Church of God

42.4% growth in the PCA

57.2% growth in the Evangelical Free Churches

Dever then asks:

"In light of your post on not losing a grip on the gospel, would you suggest that Calvinists are better evangelists? Is that what these statistics suggest? To what do you attribute the PCA's much more rapid growth?"

I would suggest that (1) the denominations which have showed decline are generally more liberal in their theology. The fact that people are leaving these denoms is no surprise to me because why would people come to church to get worldly ideas when one can just get those from the world itself? Also, (2) The denoms that have showed growth are the ones that profess the inerrancy of Scripture. However, why have the PCA and the EV Free churches grown so much? I would say that because they are relatively new, the growing curve will be pretty steep, however both of these two denoms as a whole practice SUFFICIENCY of Scripture, meaning that they preach and teach the ENTIRE Word of God and let the Spirit convict and move their congregants and do not teach "self-help" psychology.

This finding begs the question, "Why have Southern Baptists only grown 5%?" I would surmise that most SB churches DO NOT practice the sufficiency of Scripture. And what I mean, is that I doubt most pastors in the SBC preach through entire books of the Bible, preach doctrinal series, and generally strive to have a biblically-minded church. There is a big difference between stating that one believes the Bible is the Word of God and actually practicing this belief.

In conclusion, being a Calvinist does not make you a better evangelist, but placing yourself under the authority of Scripture, and witnessing faithfully for the glory of God (and NOT the for the glory of ourself), will result in denominational growth. Lost people can discern between godly intentions and ungodly ones.

With that said, growth does necessitate success. One only has to look at Joel Osteen and the Mormon Church. They are growing, but are they growing because God is blessing them?
