At the very core of Christian identity lies an all-encompassing change of loyalty, from a given culture with its gods to the God of all cultures. A response to a call from that God entails rearrangement of a whole network of allegiances. As the call of Jesus’ first disciples illustrates, “the nets” (economy) and “the father” (family) must be left behind (Mark 1:16–20). Departure is part and parcel of Christian identity.
