“I wish we could always remember, when the devil tempts us to disputes, that the disagreement of members within the church can lead to nothing else than the ruin and consumption of the whole body. How distressing, how mad is it, that we, who are members of the same body, should be leagued together, of our own accord, for mutual destruction! Now follows the remedy. The ruin of the church is no light evil, and whatever threatens it must be opposed with the most determined resistance. But how is this to be accomplished? By not permitting the flesh to rule in us, and by yielding ourselves to the direction of the Spirit of God.”
-John Calvin, commenting on Galatians 5:15-16.
