During the 1850s the RCUS also fought over the use of a liturgy. In general the Mercersburg men favored the new liturgy, which they helped write with Nevin on the committee, and the "Old Reformed Party" (the opponents), rejected it as innovative and as contrary to Reformed doctrine. The controversy, which came perilously close to causing a schism between the factions, continued until 1878, when the General Synod established a peace commission. The General Synod of 1884 approved a liturgy that was approved by the required number of Classes (first-level judicatories, equivalent to presbyteries). The controversy between the two parties ended in a compromise liturgy, and with each side having its own educational institutions: Mercersburg Seminary and Franklin and Marshall College for the Mercersburg Movement, and Ursinus College for the Old Reformed Party.
