Abstract
Employing a work of modern conceptual art, a manipulated photograph entitled ‘The Missing Person’, the author studies Thomas Aquinas on the concept of human beings as image of (the Triune) God. Typical for Aquinas’ approach is the theocentric focus of his Christian anthropology. The threefold (nature, grace, glory) ‘image of God’, a central and dynamic concept in Aquinas’ Summa Theologiae, is both descriptive and prescriptive in nature, corresponding to an account of both analogical naming of the divine ánd living according to the vocation to become more and more image of the Triune God.
