To illustrate the nature of this theandric reciprocity, Thomas invokes, as an example, the physical touch of Jesus’s hand: “he wrought divine things humanly, as when he healed the leper with a touch.” The touch of a human being is not in itself miraculous, and even in Jesus this human action is not humanly healing. The miraculous fact of the healing power of this human touch, rather, as Reginald Garrigou-Lagrange puts it, “proceeds from God as the principal cause and from Christ’s human nature as the instrumental cause.” Jesus works divine things humanly. More ultimately, Jesus wills the divine will of salvation humanly. And so he wills theandrically in the sense that what he wills has an “infinite value” that “derives from the divine suppositum that is the agent which operates”. The deifying effects of the Incarnation are thus contingent on the theandric fact of the interpenetrating unity of divine-human operations.
