Progressive Christianity is a form of Christianity which is characterized by a willingness to question tradition, acceptance of human diversity, a strong emphasis on social justice  and care for the poor and the oppressed, and environmental stewardship of the Earth. Progressive Christians have a deep belief in the centrality of the instruction to "love one another" (John 15:17) within the teachings of Jesus Christ. This leads to a focus on promoting values such as compassion, justice, mercy, tolerance, often through political activism. Though prominent, the movement is by no means the only significant movement of progressive thought among Christians (see the 'See also' links below).
