I am enjoying the new Four Views on The Apostle Paul, edited by Mike Bird. I’ve found especially interesting the essay by Luke Timothy Johnson, who sums up his essay with this:
In his most sustained reflection on the nature and task of the church, Paul proposes that the role of the church is to be the place in the world where the work of Christ in reconciling humans to God should be realized in practice by the reconciliation of Jews and Gentiles (Eph. 2:1-22) and the harmony between male and female (5:32). The task of the church, he suggests, is to be a sacrament of the world’s possibility (3:10) (p. 96).
