"In God We Trust"—The Contribution of Christian Trade Unions in European Integration.

Since World War II, the countries of Western Europe have gradually gone towards economic, social, and political integration. This was influenced by states, institutions, social partners, and churches. The Christian trade unions also contributed to that end. This contribution was the result of the interaction between the laborers' religion and their desire to act collectively. Those unions followed the social doctrines of the Catholic Church and/or Protestant Churches while strongly disagreeing with socialist or communist unions. During the Interwar period, their members were subjected to the violent actions of the totalitarian governments in many European countries. Those governments eliminated Christian unions and, in some cases, persecuted their leaders. After the war, Christian unions embraced the "Peace Project", advocating for European and global peace. They also cooperated with many political and social leaders during the formation of the EEC. Christian unions aimed at improving political systems in Western Europe, promoting freedom of religion, and defending the Communist threat. In this article, we describe the ways in which the Catholic and Protestant labor unions tried to promote political, economic, and social cooperation in Europe. To this end, we will examine their pertinent material and actions on the Old Continent. Finally, we will discuss the current challenges faced by the Christian unions and their stance towards neoliberal capitalism and globalization—these new developments in the long history of Christian Europe.
