A very interesting article contrasting the T4G conference with the Wheaton conference. 

For the T4G folks, protecting disputed doctrines against heresy is where good theology is born. Clear thinking comes from friction and protestation, from Hegelian dialectics (R.C. Sproul spoke on this), but not from compromise. The Patristic Fathers got it right whenever they were ironing out disputed doctrines and fighting against heresy, said Ligon Duncan in his talk. But on matters that were not disputed, he said, their thought sometimes got muddled up.

The exact opposite point was made at the Wheaton Conference by Kevin Vanhoozer, professor of systematic theology at Wheaton, who suggested that theologians like Wright (and, presumably Christians in general) are more often correct in matters they collectively affirm than in matters they dispute. This statement reflects the contrasting spirit of the Wheaton Conference as regards unity: It’s what we affirmthat matters. Are we on the same page on the core issues? Can we agree on the claims of the creeds? Yes? Then let’s hash out the details of theological minutia (which is definitely important) in a spirited, friendly debate as the people of God exercising the renewal of our minds (Rom. 12:2).
