Karl Rahner famously proclaimed that Vatican II marked the beginning of a new Christian epoch, that of the “world church” (Weltkirche). He also proposed that the Catholic Church develop a global pastoral-strategic plan for the world church. This recommendation needs updating. This can occur through conversation with theologians engaged with Christianity in the Global South: Lamin Sanneh and Gemma Tulud Cruz. They offer ideas regarding the translatability and emerging inclusivity involved in the concrete, localized performances of ecclesial life that constitute the world church. Combined with Rahner’s rendering of the nexus between Christology and ecclesiology, these ideas can impel and guide attempts to think through and live out the church’s catholicity today.
