"...importing monetary and broader economic language into theology informs theological systems in unique and substantive ways. To speak of Christ metaphorically as currency and coin, for instance, is to ascribe to Christ key attributes of monetary economy in ways that establish elements of Christ's identity. These attributes in turn become footholds and bearing points for subsequent theological formulations and expanding networks of doctrinal claims. The monetary metaphor may thus come to inform the logic of the entire system. As a central building block of the broader edifice, the metaphor may even be forgotten or dismissed. This can be seen in the way the metaphor of redemption, used to speak of salvation, can be repeatedly invoked in Christian context without an awareness of its thoroughly economic derivation and sense."
