Last night the congregation of Kirk of the Hills Church in Tulsa, OK, met and voted overwhelmingly to affirm the Session's decisions to:

1. Disaffiliate from the PC(USA)
2. Affiliate with the EPC
3. Affirm the ordinations of Pastors Tom Gray and Wayne Hardy

If you want to read about it there is no end of information about it out there.  This is the largest PC(USA) congregaton so far to leave the denomination and it is getting wide-spread coverage.  I would refer you to:

The church's press release about the meeting
Pastor Tom Gray's blog and his discussion of the meeting
An article in the Tulsa World about it
And a press release issued by the PC(USA) before the meeting

There is some more information as well on the Kirk of the Hills Church web site. 
At least at the moment, the Eastern Oklahoma Presbytery still lists the church on their web site since the Presbytery has yet to take formal action.

I will leave it at that and let the news accounts speak for themselves.  I would note the variation between the PC(USA) press release that mentions a "handfull" of churches interested in leaving the denomination and some of the other documents that talk about up to 200.
