Christian socialism generally refers to those on the Christian left whose politics are both Christian and socialist and who see these two things as being interconnected. This category can include Liberation theology and the doctrine of the social gospel. Christian socialists draw parallels between what some have characterized as the egalitarian and anti-establishment message of Jesus, who — according to Christian Gospel — spoke against the religious authorities of his time, and the egalitarian, anti-establishment, and sometimes anti-clerical message of most contemporary socialisms. Some Christian Socialists have gone as far as to become active Communists.
