Jonathan Edwards wrote this in his Thoughts on the Revival, speaking of the importance of “separation,” while emphasizing the humble Christian’s deportment therein:
But, on the contrary, the eminently humble Christian is ready to look upon himself as not worthy that others should be united to him—to think himself more brutish than any man, and worthy to be cast out of human society— and especially unworthy of the society of God’s children. And though he will not be a companion with one that is visibly Christ’s enemy—but delights most in the company of lively Christians, choosing such for his companions, and will be most intimate with them, not delighting to spend much time in the company of those who seem to relish no conversation but about worldly things—yet he does not love the appearance of an open separation from visible Christians, as being a kind of distinct company from them who are one visible company with him by Christ’s appointment; and will as much as possible shun all appearances of a superiority, or distinguishing himself as better than others. His universal benevolence delights in the appearance of union with his fellow-creatures, and will maintain it as much as he possibly can without giving open countenance to iniquity, or wounding his own soul. And herein he follows the example of his meek and lowly Redeemer, who did not keep up such a separation and distance as the Pharisees, but freely ate with publicans and sinners, that he might win them.
