Monastic spirituality concentrated on private disciplines, as if detaching oneself from "the world" (i.e. society) might make one holier. Anabaptist piety was similar in that regard. However, Calvin thought of sanctification as a family affair. How could one learn loving humility, patience, wisdom, and forgiveness in isolation from others?
