This is a question for Presbyterians. How does it work if a man desires the office of elder in one denomination but is a member of another? For example, he is a member of a PCA church but is seeking office in the RPCNA due to his doctrinal beliefs. This is assuming that the reason he is a member of a PCA church and not an RPCNA one is that there is not an RPCNA congregation in his area.
