"Even in the Apostles' days, Christians were too apt to strive after a wrong unity and uniformity in outward practices and observations, and to judge one another unrighteously in these matters; and mark, it is not the different practice from one another that breaks the peace and unity, but the judging of one another because of different practices. For this is the true ground of love and unity, not that such a man walks and does just as I do, but because I feel the same Spirit and Life in him, and that he walks in his rank, in his own order, in his proper way and place of subjection to that; and this is far more pleasing to me than if he walked just in that track wherein I walk."

-- Isaac Penington, 17th century Quaker
