Merton on Resisting Evil

Merely to resist evil with evil by hating those who hate us and seeking to destroy them, is actually no resistance at all. It is active and purposeful collaboration in evil that brings the Christian into direct and intimate contact with the same source of evil and hatred which inspires the acts of his enemy. It leads in practice to a denial of Christ and to the service of hatred rather than love.
