The twenty-first-century church cannot afford to neglect mission. When church and culture no longer share a common outlook, the only way forward is mission. Pope Francis recognizes this in his call for a missionary conversion of the church. Eugene Schlesinger responds this invitation in Missa Est!, a volume from the Emerging Scholars series that is a constructive work in ecclesiology that particularly focuses on the relationship between liturgy and mission in the church's life. Within, Schlesinger advances a notion of the church grounded in both liturgy and mission, where neither is subordinated to nor collapsed into the other. The church's liturgical rites disclose and enact the church's identity as a missionary community.
