Joint Declaration on the Doctrine of Justification

The "Joint Declaration on the Doctrine of Justification" (JDDJ) is a document created and agreed to by the Catholic Church's Pontifical Council for Promoting Christian Unity (PCPCU) and the Lutheran World Federation in 1999 as a result of Catholic–Lutheran dialogue. It states that the churches now share "a common understanding of our justification by God's grace through faith in Christ."^[1] To the parties involved, this substantially resolves much of the 500-year-old conflict over the nature of justification which was at the root of the Protestant Reformation.

As of 2017, the bodies representing 75% of the world's Christians have formally affirmed the Joint Declaration. Now as a five-way agreement between the Roman Catholic Church, the Lutheran World Federation, the World Methodist Council, the Anglican Communion, and the World Communion of Reformed Churches,^[2] it is, however, not without controversy.
