The Working Men's College, is among the earliest adult education institutions established in the United Kingdom, and Europe's oldest extant centre for adult education.

Christian socialism is a religious and political philosophy that blends Christianity and socialism, endorsing socialist economics on the basis of the Bible and the teachings of Jesus. Many Christian socialists believe capitalism to be idolatrous and rooted in the sin of greed. Christian socialists identify the cause of social inequality to be the greed that they associate with capitalism. Christian socialism became a major movement in the United Kingdom beginning in the 19th century. The Christian Socialist Movement, known as Christians on the Left since 2013, is one formal group, as well as a faction of the Labour Party.
