Catholic social thought and teaching is sometimes conceptualised using an historical or principles-based approach. This paper proposes an alternative framing, construing Catholic social teaching (CST) as a multi-layered phenomenon that can be grouped into three broad tiers, each with a distinctive role. This framing is not intended to supercede the others, nor is it inconsistent with them. The proposal emerges out of a series of discussions hosted by the Catholic Agency for Overseas Development, a Catholic UK-based development agency, member of Caritas Internationalis, and an official agency of the Bishops’ Conference of England and Wales. The paper operates on two levels simultaneously: it attempts a distinctive reframing of CST using a distinctive source, and it attempts an enactment of CST methodologically and structurally. Construing CST as a multi-layered phenomenon that can be grouped into three broad tiers provides a clarity that empowers us in two ways. First, it clarifies the distinctive role of CST at each level. Second, it makes clear that CST is a work of the Spirit rather than a human phenomenon. Such an understanding of CST brings out with particular clarity a vision of the role, purpose, and even the agency of Catholic social thought in relation to a troubled world.
