“ Jesus’s use of the phrasing “a new commandment” is frequently scanted in light of its implicit ramifications. Because Jesus at the Last Supper has executed the “new covenant” with his disciples, the Great Commandment itself now acquires an unprecedented meaning. Its new meaning belongs to this sudden revelation not merely about who God is but also about what love is. Previously the Great Commandment bade us to love God and our neighbor. Now this love can be comprehended only in an incarnational situation. Its incarnate presence is the activation of profound rhizomic relations that explode from the center toward the ends of the earth. We are commanded to be incarnational in relation to one another just as God at the cross was incarnational in Christ. . . . We are no longer simply Christ’s “followers - the pre-Easter form of relation to a master-and-teacher that is conventionally called “disciple” - but also perpetual Christ incarnators . . . ”
