Brothers, I know that this is not the most scintillating topic, but I am hoping to gain some insight from my Puritan Board brethren on the questions I pose below. And your thoughtful response just might help promote the peace, purity, and unity in a small and humble portion of Christ's church. Presbyterian Book of Disciplines (BD) differ from body to body as to whom they grant the right to file a formal complaint against a judicatory (session or presbytery). For example, see the following from the OPC, PCA, and RPCNA. OPC--"It may be brought by an officer or other member of the church against the session or the presbytery to which he is subject, by one session against another session, by a session against the presbytery which has jurisdiction over it, or by one presbytery against another presbytery" (BD IX.1). PCA--"It is the right of any communing member of the Church in good standing to make complaint against any action of a court to whose jurisdiction he is subject..." (BCO 43-1). RPCNA--"It may be made by the parties concerned, by members of the court, or by any interested persons*" (BD E-15). You can see how the right to complain varies from church to church. In the PCA, the right to complain is restricted, so that one can only complain against a court to which the complainant is subject (church member against session, presbyter against presbytery). In the RPCNA, it would seem, the right to complain is extended very broadly to include "any interested party" (I could not determine how precisely the book defines 'interested party' from the cross-reference noted with the asterisk, though I am certain it is not just anybody.). In the OPC, the right to complain appears to be more broad than the PCA but less broad than the RPCNA. My main question is, who should have the right to complain against a court of the church? What biblical and/or logical principle(s) limit it? Should I be able to complain against a session of a church I am not a member or against a presbytery of which I am not a presbyter? Thanks, in advance, for your time.
