Thanks for the welcome Pilgrim, and I guess differences were almost unavoidable. I was familiar with Keil's treatment and dug out my copy. Owen differs from Keil significantly in Covenant Theology but it always feels to me that Keil is a bit too literal (if that's possible -I mean it in a good way!) His CT seems to stop "just" short of Christological OT redemption...in a way that John Owen doesn't. It was consideration of OT salvation that led me to John Owen's position on CT. As I'm sure you know he remained paedobaptist (though congregational independent and opposed to both presbyterianism and episcoplianism) but not through his covenant theology. His reasons were interesting but, I think, flawed.

Notice though that Keil gives me my points on "knowing" God in contradiction of "JEdwards" interpretation.
Worth pointing out also that Keil gives the New Covenant Jerusalem (31:40)a wholly regenerate aspect(all holiness to the Lord without a Temple within) in contrast to the OT city (Old COvenant)which had a Temple. Wonderful picture of a regenerate church membership co-extensive with New Covenant boundaries contrasted with the Old Covenant mixed multitude typical covenant with a holy core.
