The early church writer Irenaeus is often seen as something of a poster boy for one view of the atonement. That view is known as “Christus Victor”, after Aulen’s 1931 book of the same name. Aulen is so influential that his reading of Irenaeus is often assumed. All too frequently Irenaeus himself is ignored, and Aulen is allowed to speak for him.
This matters, of course, because Aulen argues that the early church universally supported Christus Victor, and any kind of propitiatory language was a much later innovation. If this were true, then a degree of suspicion would rightly fall on the idea that the church only perceived the correct interpretation of Scripture some hundreds of years after it was written—an idea that is of course not impossible, but is also not a position to assume lightly.
Jeffery, Ovey & Sach (2007) give an excellent survey of early church writers, arguing that all of those surveyed, “without exception, believed the doctrine of penal substitution” (p. 163—penal substitution involves propitiation). They ably demonstrate this point. Aulen claimed that penal substitution arose as one result of a process of theological development whose trajectory was more dominated by Latin thinking than reference to the Scriptures. This claim is clearly inaccurate, and arguably more the product of Aulen’s time and a general desire to identify a “primitive” Christianity, than careful study of the texts available.
Irenaeus, though, seems to be generally regarded as speaking only of Christus Victor.
