What did the social gospel movement, involving groups such as the salvation army, do impact poverty? what does temperance mean?

The Social Gospel was a movement in Protestantism that applied Christian ethics to social problems, especially issues of social justice such as economic inequality, poverty, alcoholism, crime, racial tensions, slums, unclean environment, child labour, inadequate labour unions, poor schools, and the danger of war. It was most prominent in the early-20th-century United States and Canada. Theologically, the Social Gospellers sought to put into practice the Lord's Prayer (Matthew 6:10): "Thy kingdom come, Thy will be done on earth as it is in heaven".[1] They typically were postmillennialist; that is, they believed the Second Coming could not happen until humankind rid itself of social evils by human effort.[a] The Social Gospel was more popular among clergy than laity.[2] Its leaders were predominantly associated with the liberal wing of the progressive movement, and most were theologically liberal, although a few were also conservative when it came to their views on social issues.[3] Important leaders included Richard T. Ely, Josiah Strong, Washington Gladden, and Walter Rauschenbusch.[4]
