By the 1850s, New School Presbyterians in the North had moved to more moderate positions and reasserted a stronger Presbyterian identity. This was helped in 1852 when the Plan of Union between the New School Church and the Congregationalists was discontinued. Northern Presbyterians of both the Old and New School participated in the Christian Commission that provided religious and social services to Union soldiers during the Civil War. Furthermore, both schools boldly proclaimed the righteousness of the Union cause and engaged in speculation about the role of a newly restored America in ushering in the millennium. This was, in effect, the Old School's repudiation of its teaching against involving the church in political affairs.
