Religious Social Democrats of Sweden (Swedish: Socialdemokrater för tro och solidaritet) formerly the Swedish Association of Christian Social Democrats (Swedish: Sveriges kristna socialdemokraters förbund, commonly known as Broderskapsrörelsen, "the Brotherhood Movement") organizes religious members of the Swedish Social Democratic Party. The organization was founded in 1929 as an organization for Christian social democrats. Since 2011, it has been open for members of all religions. It is an associate member of the International League of Religious Socialists.
The former Prime Minister of Sweden Göran Persson is a member of the organization.
The Swedish Association of Christian Social Democrats has received criticism for its cooperation with various alleged islamist and anti-Zionist groups and people. In November 2005 the organization together with the Social Democratic Students of Sweden and the Muslim Council of Sweden invited the Palestinian-British academic Azzam Tamimi to hold a speech at a seminar at the entitled Islam and Democratic Development (Swedish: Islam och demokratiutveckling). Tamimi has referred to Israel as a "cancer" and expressed support for the violent struggle of Hamas and Hizbollah against Israel.
In March 2007, the Swedish Association of Christian Social Democrats together with the workers' educational association ABF and the journal Folket i Bild/Kulturfront invited the Israeli-born activist and musician Gilad Atzmon to hold a speech at a seminar in entitled Iraq, Palestine and Afghanistan: same occupation? (Swedish: Irak, Palestina och Afghanistan: Samma ockupation?). The invitation led to strong criticism from the chairman of the Swedish Committee Against Antisemitism (SKMA), who called Atzmon a "notorious anti-Semite". In a reply, Ulf Carmesund of the Swedish Association of Christian Social Democrats countered that SKMA is on a dangerous path, devaluing the whole concept of antisemitism, when they attempt to apply the term to persons such as Atzmon. Gilad Atzmon belongs to the group of Jews that distance themselves from Israels policies, Carmesund explained. Atzom is critical of Israels policies and of organizations that spuriously support Israel in the name of all Jews.
