heresy. 20th century Confessional revision Briggs' heresy trial was a setback to the movement for confessional revision, which wanted to soften the Westminster Confession's Calvinistic doctrines of predestination and election. Nevertheless, overtures continued to come before the General Assembly. In 1903, two chapters on "The Holy Spirit" and "The Love of God and Missions" were added to the Confession and a reference to the pope being the anti-christ was deleted. Most objectionable to conservatives, a new "Declaratory Statement" was added to clarify the church's doctrine of election. Conservatives criticized the "Declaratory Statement" and claimed that it promoted Arminianism. The 1903 revision of the Westminster Confession eventually led a large number of congregations from the Arminian–leaning Cumberland Presbyterian Church to reunite with the PCUSA in 1906.

The department, created in 1903 to minister to working class immigrants, was the first official denominational agency to pursue a Social Gospel agenda. According to church historian Bradley Longfield, Stelzle "advocated for child-labor laws, workers' compensation, adequate housing, and more effective ways to address vice and crime in order to advance the kingdom of God." After a reorganization in 1908, the work of the department was split between the newly created Department of Church and Labor and the Department of Immigration. While the Social Gospel was making inroads within the denomination, the ministry of baseball player turned evangelist Billy Sunday demonstrated that evangelization and the revivalist tradition was still a force within the denomination. Sunday became the most prominent evangelist of the early 20th century, preaching to over
