John’s ecclesiastical career illustrates a tension, common in twelfth-century Christianity, between a desire to engage with the world and the traditional pursuit of piety in monastic isolation. The mosaic captures this tension. Christ is shown resolving a realistic human problem, one of whose subjects is African--indicative of the order’s trans-regional mission. However, the work is located over the gate in the walls of the monastic complex. The urge to separate the activities of a religious order from the world – even if they were engaged with the world – was still strong.

As for the Cosmati mosaic itself, the scene should not necessarily be understood as an abstract meditation on racial egalitarianism. Among other activities, the Trinitarians purchased Afro-Italian slaves and exchanged them for captive Christians. The mosaic thus brings to mind the founding myth and the public activities of the order. A helpful analogy is a modern-day corporate logo.
