by Augustine, a fifth century theologian who describes a Trinitarian formula in the image of God. Augustine's Trinitarian structural definition of the image of God includes memory, intellect, and will. According to Augustine, "will […] unites those things which are held in the memory with those things which are thence impressed on the mind's eye in conception." The influence of Greco-Roman philosophy, particularly Neo-Platonic, is evident in Augustine's assertion that the human mind was the location of humanity, and thus the location of the image of God. Augustine believed that, since humanity reflects the nature of God, humanity must also reflect the Triune nature of God. Augustine's descriptions of memory, intellect, and will held a dominant theological foothold for a number of centuries in the development of Christian Theology. Medieval interpretation of the substantive view Medieval theologians also made a distinction between the image and likeness of God. The former referred to a natural, innate resemblance to God and the latter referred to the moral attributes (God's attributes) that were lost in the fall. Aquinas, a medieval theologian writing almost 700 years after Augustine, builds on the Trinitarian structure of Augustine but takes the Trinitarian image of God to a different end. Like Irenaeus and Augustine, Aquinas locates the image of God in humanity's intellectual nature or reason, but Aquinas believes that the image of God is in humanity in three ways. First, which all humanity possess, the image of God is present in humanity's capacity for understanding and loving God, second, which only those who are justified possess, the image is present when humanity actually knows and loves God imperfectly, and thirdly, which only the blessed possess, the image is present when humanity knows and loves God perfectly. Aquinas, unlike Augustine, sees the image of God as present in humanity, but it is only through humanity's response to the image of God that the image is fully present and realized in humanity. Medieval scholars suggested that the holiness (or "wholeness") of humankind was lost after the fall, although free will and reason remained. John Calvin and Martin Luther agreed that something of the imago dei was lost at the fall but that fragments of it remained in some form or another, as Luther's Large Catechism article 114 states, "Man lost the image of God when he fell into sin."
