To mark the 1700th anniversary of the Nicene-Constantinopolitan Creed, the Dutch Churches have organised some events. On Friday, 6 June, a symposium will be held in Huize Heyendael, Nijmegen, on “the Nicene Creed and its influence on the Eastern Orthodox and Catholic traditions”, with an exchange of views between theologians of the two traditions – John Behr (St Irenaeus Orthodox Institute) and Marcel Sarot (Faculty of Theology, Tilburg University). On Saturday, 14 June, a national ecumenical commemorative celebration organised by the Council of Churches will be held in Gouda (at 2 pm, Church of St John). Before this, there will be an ecumenical event dedicated to young people (15 to 35 years) in preparation for the celebration. The programme also features a musical dialogue with the composer of a new musical version of the Nicene Creed, an explanation of the Creed, and an exchange of views in groups. Young people will then move to the venue where the celebration will be held. “On the eve of Holy Trinity Sunday, with this celebration, the member Churches of the Council of Churches want to celebrate unity in faith”, the Council’s website reads. The celebration was organised by the Nicaea 2025 Committee. The Nicene Creed was drafted in 325 during the First Council of Nicaea (now Iznik, Turkey) which was convened by Emperor Constantine the Great to affirm the doctrine of the Trinity and reject Arianism – a doctrine that denied the divinity of Christ. The Creed was then revised in Constantinople in 381 to clarify the doctrine of the Holy Spirit. This Creed is still fundamental for many Christian denominations today.
