Our unity is instead a unity of respect for the truth and for truth-in-practice, that sees in each other such a dogged commitment to God's word in both faith and practice that we want to be together promoting biblical Christianity, even (and especially) in the way we handle the points of principle on which we seriously disagree.
--Ligon Duncan TG4
The Gospel needs to be central in our lives. Yes, we have disagreements and differences. If we are truly committed to the Word of God, then all of those disagreements and differences should be minor in comparison to the commonality of the Gospel.
