Study Document of the Lutheran-Roman Catholic Commission on Unity

The Lutheran World Federation

Pontifical Council for Promoting Christian Unity

With the present study document on the apostolicity of the church, the Lutheran-Roman Catholic Commission on Unity completes, after working from 1995 into 2006, the fourth phase of the Lutheran-Catholic world-level dialogue. The Commission was mandated and its members were appointed by their churches, as these acted through the Lutheran World Federation and the Pontifical Council for Promoting Christian Unity. The study document is presented to these two mandating bodies, and so to the respective churches, but as well to the wider public of persons and groups engaged in the ecumenical movement. The Commission hopes that the study will open fresh perspectives in the area of ecumenical ecclesiology and will throw light on pathways along which significant steps may be taken toward the goal of full communion be-tween the Catholic Church and the Lutheran churches of the world.

The document offers, first, a careful examination of New Testament texts pertaining to the apostles and the main aspects of apostolicity (Part 1), and then sets forth the outcome of investigations from three specific perspectives on apostolicity, namely as a creedal attribute of the church (Part 2), as a characteristic of church ministry (Part 3), and as a decisive quality of the teachers and doctrine which our churches require in order to remain in the truth of the gospel (Part 4).
