The Presbytery of Stockton in California is trying to establish some clarity for Presbyterians when we discuss "Essential Tenets." Presbyterians say they have Essential Tenets but they never identify them (or, I should say, the national denomination never defines them, except for support of women's ordination, which is explicitly endorsed by only one of our Confessions.).
Stockton is attempting to describe some Essential Tenets as guidelines. I appreciate their hard work and irenic spirit.
