"Bonhoffer offers an insight into friendship. He notes that it is not easy to classify this relationship sociologically, unlike the relationships which derive from, what he refers to as, the divine mandates, namely marriage, work, the state and the church. Because it cannot be classified or defined as such, friendship cannot be protected by the courts or society in general. Rather, friendship develops in freedom, or as Bonhoffer says, friendship appeals to the necessitas of liberty. Friendship is defined by "the binding content between two people." … The Christian's service of God entails service of one's neighbor. The community united in worship is a manifestation of God's presence. In worship we "rehearse" or "act out" what we are to become as God's people, namely "One." Moreover, in a sense we "worship one another," in that we are aware that each member of the community is an image of the living God."
