Community life, not a dreamy ideal, said Bonhoeffer, but an often difficult initiation into the “divine reality” that is the church. That is, the church exists as a brotherhood established by Christ, even if it doesn’t feel like it in a given moment. The martyred Lutheran pastor taught that struggles within the community are a gift of God’s grace, because they force its members to reckon with the reality of their kinship, despite their brokenness.
