Roman Catholicism and Christian Unity

from Christ the Center

Mark Gilbert joins Camden Bucey to examine what Protestants and Roman Catholics mean when they speak of Christian unity. Drawing on Gilbert’s conversion from Roman Catholicism, they contrast a unity grounded in the Spirit’s work through the Word with Rome’s institutional claim to mediate grace and gather humanity into one visible communion. The conversation turns to Vatican II and Karl Rahner’s doctrine of the “anonymous Christian.” Camden and Mark consider Rahner’s anthropology, his account of God’s self-communication, and the influence of this framework on Roman Catholic inclusivism. They conclude with a pastoral call to speak with clarity and charity and to offer the assurance found only in the finished work of Christ.
