In my blog a few weeks ago about being Presbyterian, I mentioned that a distinguishing mark of our tradition is that we adhere to the Westminster Confession of Faith (WCF) (the Heidelberg Catechism is good too). As a follow-up to that idea, I thought it might be helpful to take this a step further and consider some good reasons why a church should be “confessional” — that is, why it should hold to an established confession of faith.
