I've recently read through (and thoroughly enjoyed) the Heidelberg Catechism, and have now started on the Westminster Confession of Faith. In chapter two of the WCF, it states that God is "without body, parts, or passions." I agree with the first two, but I'm not sure what is meant by "passions." Certainly our God has no sinful passions, but doesn't the very idea of His jealousy, anger, wrath, etc. imply a kind of divine passion for good? My understanding of the Hebrew term CHESED (mercy) is that it derives from a word meaning "to have an ardent desire," indicating that God's passion is to do mercy. The sum of John Piper's work would seem to point toward the idea that God has a passion to make His glory known.
So, am I misunderstanding the WCF? Am I interpreting "passions" wrongly? What does it mean to affirm that God is without passions, and why is it important? Do you believe God has holy passions? What were the Westminster divines getting at?
