One of the new titles in the recent Baker catalog (due for release this month) is Matthew Bates’s Salvation by Allegiance Alone: Rethinking Faith, Works, and the Gospel of Jesus the King. According to Michael Bird’s blurb,
Matthew Bates argues that faith or believing is not mere assent, not easy believism, but covenantal loyalty to the God who saves his people through the Lord Jesus Christ. Bates forces us to rethink the meaning of faith, the gospel, and works with a view to demonstrating their significance for true Christian discipleship. This will be a controversial book, but perhaps it is the controversy we need!
I haven’t read the volume yet, and the book’s apparent thesis will doubtless be controversial in some quarters as Bird suggests. But, this thesis is also something that definitely resembles prior thinking.
Dietrich Bonhoeffer had the formulation “only he who believes is obedient, and only he who is obedient believes”—because believing is a response to an announcement that has the nature of a command (Cost of Discipleship, 69–70). Or, as Augustine suggested, the notion of faith may have two aspects:
We use the word in one sense when we say, “He had no faith in me,” and in another sense when we say, “He did not keep faith with me.” The one phrase means, “He did not believe what I said;” the other, “He did not do what he promised.” (On the Spirit and the Letter 31.54)
Or, indeed, in Romans, as sometimes is bypassed all too easily, part of Paul’s portrait of Abraham is precisely that his faith was also obedient: Abraham becomes the father not only of individuals within the scope of his biological descendants, but to all “those follow in the footsteps of the faith our father Abraham had while he was uncircumcised” (Rom 4:12; τοῖς στοιχοῦσιν τοῖς ἴχνεσιν τῆς ἐν ἀκροβυστίᾳ πίστεως τοῦ πατρὸς ἡμῶν Ἀβραάμ; cf. Rom 1:5, 3:31; Dunn, Romans, 211–12).
