Is the Old Testment Still a Source for Theology and Spirituality for Christians?

Does the Old Testament still matter for Christians? I think most of us have asked that question at some point. For many of us, the Old Testament is weird and scary, full of rituals that are foreign and irrelevant. Others of us wonder what the point of studying the Old Testament is now that we have Jesus and the New Testament. I mean, didn’t his coming make all of that pointless? Can’t we kind of move on and ignore it now?

Downplaying or denying the Old Testament’s importance or binding nature as revelation has been a perennial temptation for Christian theology. Looking at the ‘newness’ of the New Testament and the finality of Christ, some of us can only imagine that having a sense of abolishment and denial instead of one of fulfillment and completeness. This was true in the earliest church controversies into much later periods such as Francis Turretin’s own time. Apparently, some Anabaptists at the time denied this, and so Turretin took up arms to defend the Old Testament, dedicating a lengthy question (Institutes of Elenctic Theology, Vol. 1, Q. 8) in his section on Scripture to establishing the continuing authority and authenticity of revelation of the Old Testament alongside the New Testament as part of the rule of faith and conduct for the life of the church. (Side-note: I’m not charging current Anabaptists with this, just stating Turretin’s position. So, if you are one, and this doesn’t apply, excellent!)

Regular readers of the blog will know that the unity of revelation in the Old Testament and New Testament is a theme that’s shown itself to be increasingly important for all sorts of issues. Again, then as now, some will deny the Old Testament’s authority in order to propose revisions in our concept of God, of salvation, and the nature of God’s Word. I figured it would be useful to trace out Turretin’s case here for future reference and present edification. Keep reading
