Back in the summer the General Assembly voted to amend its constitution to change the way the Administrative Committee is funded. Right now, giving in the PCA is done on a voluntary basis. Amendment 14-1 would have completely changed that from voluntary giving to involuntary. Amendment 14-2 would redefine "voting membership" for General Assembly by creating new rules for who could vote at GA. According to this amendment, for a teaching elder to get to participate at GA, his church would have to pay the full amount established by the AC committee proposal, plus, he would also have to pay an additional personal tax on top of that. If these conditions are not met, then not only would he not get to vote, but the church would be reported to the GA.
However, even though GA voted in favor of these amendments, for them to be adopted, the presbyteries had to vote on them. For them to pass,2/3 of the 79 presbyteries (53) would have to vote in favor of the amendments. For them to fail, over 1/3 of the presbyteries (27) would have to vote no. Well as of yesterday, the New York State Presbytery became the 27th to vote down 14-1 and the Presbytery of Eastern Carolina became the 27th to vote down 14-2. This means that even thought there are 23 presbyteries that still have to vote, the magical number of 53 cannot be obtained, so the amendments fail.
For a complete list of which presbyteries have voted for and against, see this article at The Aquila Report.
