The Leuenberg Agreement or Leuenberg Concord is an ecumenical document adopted in 1973 by major European Lutheran and Reformed churches at the Swiss conference centre Leuenberg (near Basle). Under this agreement the churches agree on a common understanding of the Gospel, including elementary agreement on important doctrines including christology, predestination, Eucharist and justification. They declare church fellowship, understood as pulpit and table fellowship as well as full communion in witness and service.
The number of churches involved has grown over the years, and now includes several Methodist churches.
The churches involved were originally joined in the "Leuenberg Church Fellowship". In 2003 this was renamed the "Community of Protestant Churches in Europe".
