As I go to Presbytery this weekend I am leaving you with this video made by Reclaim Biblical Teaching. This is Hector Reynoso who "is Pastor of the Principe de Paz Presbyterian Church in south Texas. He was a candidate for Vice Moderator of the General Assembly in 2010. He has a heart for the PCUSA." He offers some of his history as a Presbyterian, his deep concerns and encouragement.
You can find other excellent resources and material at Reclaim Biblical Teaching.
