Abstract

This chapter examines how it is that one can know God is Trinity. It begins with a discussion of early medieval attempts to prove that God is Trinity by means of rational argumentation. And, while it is clear that this tradition had some influence in the eleventh and twelfth centuries, one observes that formal demonstrations for the triunity of God waned by the thirteenth century. In the subsequent sections of the chapter, we explore how medieval Christians argued that the Trinity is known through vestiges, Scripture, the Son (cognitio per Filium), and prayer.
