“Theological ethics should not in any way try to say directly what God’s command is. It should not make appeal to the truths supposed to lie in nature as creation of God, nor appeal to this, that, or the other text in the Bible. such ethics has to serve the Word of God, even as theology should. It must not anticipate that Word, nor may it obstruct that Word by setting up a human law. The particular thing incumbent upon such ethics is to take the Word of God as being God’s Word, and to point out the way whereby the relative necessities of our existence as creatures can become the Word of God’s revelation to us. This duty must be discharged by ethics in the light of what scripture proclaims. But it is not called upon to determine to what extent they are his, for this is solely the business of God’s Word. An ethics that thinks it can know and set forth the command of God, the Creator, plants itself upon the throne of God: it stops and poisons the wells and is more fraught with peril to the Christian life than all cinemas and dancing-saloons piled together.” (The Holy Spirit and the Christian Life, Louisville, 1993, 9–10.)
Hmmm.
What Barth is anxious to oppose here, and throughout this section of his lecture, is a view in which natural law is perspicuous. Such a view is connected to an understanding of the analogy of being to imply that we have a created capacity or feature of our constitution (some kind of substantive understanding of the image of God) that links us, in some way, to God. Barth sees this as undermining the absolute distinction between creature and Creator. Any knowledge we have of God through creation is not something there to be discovered, but a gift continually given by the Holy Spirit who animates creation, not simply as a predictable force, but as the personal presence of God himself.
I think this is, at one level, a really good point. We don’t know what creation means apart from God’s active revelation to us (and that means we don’t fully understand it apart from Christ). We’re kidding ourselves if we think that moral order can just be read-off creation without difficulty. The knowledge of its meaning and significance is a gift of grace that we should not “take for granted”.
That said, I’m not happy with Barth’s total hesitancy. For while it preserves against an overconfident natural moralism, it seems to deny the faithfulness of God. Barth’s parallel thinking in relation to Scripture helps us. Just as we might feel uncomfortable with the sense that we can’t depend on Scripture in the sense of “taking it for granted”, so we may, I think, feel uncomfortable with the sense that we can’t rely on the stability and meaningfulness of created moral order.
We ought, I think, to distinguish two senses of taking something for granted. On the one hand, we shouldn’t take either created moral order or scripture for granted in the sense that we shouldn’t forget that we are, in fact, talking about revelation, we are talking about a gift of knowledge that is not simply “native” to us. But on the other hand, there is a sense in which we should take both scripture and natural moral order for granted, in the sense that they have, in fact, been granted, and God is faithful to his gift. I am not sure Barth’s insistence that we should never imagine we can “know and set forth the command of God” is not in fact ultimately a failure to accept what God has in fact given.
Could someone who understands Barth better tell me why I’m wrong?
