The national ministries would continue only as they are funded by their respective supporting constituencies. Synods could meet to determine strategies for mission including the creation of new congregations. After five years, with a majority vote by the Presbyteries in both synods, General Assembly could meet to see if the impasse can be resolved. If not we continue under this arrangement for another pre-determined amount of time. Pa. Local option is congregational, not Presbyterian Gene Huff's suggestions seem reasonable on the surface, but like most every other argument in favor of this issue it failS to understand the nature of Presbyterian ordination.
All ordinations are the act of the whole church.
An ordained officer is not just a leader for their local congregation, they become a leader for every church and can serve in the judicatories that have oversight and responsibility for all churches. What Gene proposes would require that we change our whole understanding of the ordained office and since that is the basis of our connectional government system, much of that system would have to change as well. Imagine what would happen iF an openly gay man, serving at the presbytery level, becomes the chair of an administrative commission that is overseeing a church that doesn't accept his ordination as valid. Or, what if a lesbian woman is ordained in one church then seeks to transfer her membership to another church. Gene wants to make this look simple and the fact is there is nothing simple about it the way our system works.
