Reformed Presbyterian Church, Evangelical Synod

[2] The denomination subscribed to the 1647 version of the Westminster Confession of Faith; however, the plan of union to form the denomination, in a concession to the largely premillennial Evangelical Presbyterian Church, called for modifications to the Larger Catechism to make it more hospitable to those who held to a premillennial eschatology.

[4] The RPCES had also planned to include resolutions warning members against the evils of dancing, liquor, television, gambling and tobacco, again, in a concession to the Evangelical Presbyterian Church's Bible Presbyterian heritage, yet these resolutions, despite being a basis for the merger, had no binding legislative power.

[3] The Orthodox Presbyterian Church invited the RPCES to organic union third time (OPC had fraternal relation with the Evangelical Presbyterian Church (1961) The OPC had extensive contact with this latter group already since 1945, when a committee was established to investigate the possibility of union with them 2 times, in 1949, and in 1959 unsuccessful.)

[6] At the time of the merger the RPCES had 25,718 communicant members in 187 congregations served by 400 teaching elders.

From its founding date, the RPCES experienced a rapid membership growth, more than 400 percent.
