Christian left

[2][3] As with any section within the left–right political spectrum, a label such as Christian left represents an approximation, including within it groups and persons holding many diverse viewpoints.

The most common religious viewpoint that might be described as left-wing is social justice, or care for impoverished and oppressed minority groups.

Supporters of this trend might encourage universal health care, welfare provisions, subsidized education, foreign aid, and affirmative action for improving the conditions of the disadvantaged.

With values stemming from egalitarianism, adherents of the Christian left consider it part of their religious duty to take actions on behalf of the oppressed.

[5] The term social justice was coined in the 1840s by Luigi Taparelli, an Italian Catholic scholar of the Society of Jesus, who was inspired by the writings of Thomas Aquinas.

For much of the early history of anti-establishment leftist movements, such as socialism and communism, which was highly anti-clerical in the 19th century, some established churches were led by clergy who saw revolution as a threat to their status and power.

Early socialist thinkers such as Robert Owen, Henri de Saint-Simon based their theories of socialism upon Christian principles.

From St. Augustine of Hippo's City of God through St. Thomas More's Utopia, major Christian writers had expounded upon views that socialists found agreeable.

Other common leftist concerns such as pacifism, social justice, racial equality, human rights, and the rejection of excessive wealth are also expressed strongly in the Bible.

In the United States during this period, Episcopalians and Congregationalists generally tended to be the most liberal, both in theological interpretation and in their adherence to the Social Gospel.

[11] Martin Luther King Jr. was an American Baptist minister and activist who became the most visible spokesman and leader in the civil rights movement from 1955 until his assassination in 1968.

The group was created to harness the moral authority and organizing power of black churches to conduct nonviolent protests in the service of civil rights reform.

His nonviolent thought was also based in the injunction to turn the other cheek in the Sermon on the Mount, and Jesus' teaching of putting the sword back into its place (Matthew 26:52).

In his famous "Letter from Birmingham Jail", King urged action consistent with what he describes as Jesus' "extremist" love, and also quoted numerous other Christian pacifist authors, which was very usual for him.

It arose at a time when Catholic thinkers who opposed the despotic leaders in Southern and Central America allied themselves with the communist opposition.
