The World Conference of Life and Work (Swedish: Stora ekumeniska mötet) was held on the initiative of Church of Sweden archbishop Nathan Söderblom in Stockholm, Sweden 1925 to discuss social cooperation.
[1] Attending the meeting were most major Christian denominations, however the Catholic Church and the Pentecostal movement didn't show up.
[2] Prior to the conference, Söderblom had put efforts into ecumenical discussions among churches, and peace talks during World War I.
Among these discussions was the World Alliance for Promoting Friendship among the Churches in 1919, which was the first time Christians from both sides of the war met again.
It was intended that theological differences be kept out with the slogan "Doctrine divides, while service unites", which turned out to be hard to achieve.
