As I wrote previously, the OPC's General Assembly, with its delegated representation, has the structural and institutional weaknesses of the United States Senate: this poses a great danger to the Orthodox Presbyterian Church. Meanwhile, the PCA's General Assembly, which permits (at least nominally) a practically universal membership of all the Church's congregations and teaching elders, has the structural and institutional weaknesses of the United States House of Representatives: this poses a great danger to the Presbyterian Church in America.
Since the United States Congress was deliberately designed so that the weaknesses of each of its two Houses are compensated for by the other House's strengths, and since I have flogged ecumenism whenever and wherever I've been able, one might expect me to facilely suggest the two denominations merge and let their two General Assemblies balance each other out. However, the structure of presbyterian Church government will not allow for this simple solution.
Presbyterian governmental structure, gleaned from Acts 15 and other bits and scraps of relevant Scripture, is rather simple. It calls for a graded, or hierarchical, series of Church courts. A council of ruling and teaching elders governs each level, or manifestation, of the visible Church. (For what I mean by "the visible Church," see Westminster Confession of Faith chapter 25.) In both the OPC and the PCA, a session governs the local congregation, a presbytery governs the several congregations of a designated geographical region (also known as a "Regional Church"), and a general assembly governs the entire denomination. These courts necessarily relate to each other in a hierarchical fashion; to do otherwise would simply not be presbyterian. Therefore, a faithfully presbyterian form of Church government has no room for two Church courts which must cooperate with each other after the manner of the Houses of the United States Congress.
Nonetheless, there's a rather simple way to draw on the institutional strengths of the systems of representation of both the OPC and the PCA. Historically, and in several contemporary cases, presbyterian denominations have had another level of Church court: the synod. The synod is an intermediary court between the presbytery and the general assembly. It functions much as a presbytery does in overseeing the affairs of a designated geographical region within that of the larger denomination. Unlike a presbytery, however, the synod is not a court of original jurisdiction. Local sessions are responsible to oversee (and discipline when necessary) members of the congregation, and presbyteries oversee (and discipline when necessary) ministers of Word and sacrament. (Ministers are members of the regional Church, not the local Church.) Thus, in matters of Church discipline, synods are appellate courts only.
I suggest, then, that both the OPC and the PCA institute synods in their respective communions. These synods could have the universal membership of the PCA's General Assembly: every teaching elder and two (for the sake of argument) ruling elders from every congregation. On the one hand, this would broaden the range of perspectives of those overseeing the work of presbyteries, something the OPC desperately needs. On the other hand, the number of members at any given synod would not be so large as to make genuine debate impossible, which would address the problem of the PCA's General Assembly.
Under my proposed system, commissioners to the General Assembly would be drawn from presbyteries according to some formula set forth in a Form of Government. This would bypass both the risk of synods bottlenecking representation and the risk of presbyteries favoring only a few particular men as their (virtually) permanent commissioners. This system would allow for easier practical functioning of the General Assembly (due to more manageable numbers) and providing for lighter dockets if more disciplinary cases can be resolved by synodical courts.
Our national government's structure is remarkably robust, designed to restrain untoward ambition and encourage healthy cooperation. Its genius is perhaps best demonstrated by the little-celebrated fact that it has endured despite the often foolish choices of legislator the American people make. While the general structure of presbyterian Church government is dictated by Scripture, presbyterians have a great deal of freedom to order its institutions according to the light of nature and Christian prudence. The institutional designs of the OPC and the PCA emerged at their foundings and were based on assumptions because the founders were focused more on doctrinal problems. Now is an opportune moment to take a deep breath and consider how better to order our two houses.
