The June 24 date seems significant. There are at least three PC(USA) congregations in my area holding similar votes on that day. Looks like it was timed to coincide with the EPC GA.
No, the EPC General Assembly is going to be too busy to care. It gets scheduled when it gets scheduled. Remember that within BOTH the PCUSA and the EPC, there is a procedure for leaving the denomination. In the EPC, a Congregational meeting is held, and a vote of the congregation is taken. If in favor of Leaving, another congregational meeting is scheduled, with officials from the Presbytery in attendance and having floor privilages. The issue is then debated. After three months, ANOTHER congregational meeting is held for the final vote. If the result of that vote is for leaving, the Presbytery IMMEDIATELY dismisses that congregation...with all assets as per EPC constitution...to either independence, or another denomination.
