St. Gregory of Nazianzus
If you continue in my word, you are truly my disciples; and you will know the truth and the truth will make you free.
John’s gospel takes up the theme of truth with notable frequency, and it is worthwhile for us as Christians constantly to take up this theme as well. Whether in our prayer, work life, or social life, our play, creative pursuits, or our time alone, we should remind ourselves that Jesus has claimed to be the Truth. Truth for us is therefore not some celestial force or an impersonal ideal; it is rather a person who graciously invites us into a deep and intimate knowing.
It is this very personhood, however, that begins to present our normative categories with some resistance, confusion, and misunderstanding. We may theorize about an idea all we like; but the depth and profundity of a personality will never fit easily into any theoretical category you or I propose. For if God is not simply an impersonal force or ideal, but a person, we may know of God only that which God has revealed. About a force, we may speculate; but to know a person is to open one’s self to the vulnerability of encounter. Encounter that might even change the nature of the inquirer.
It is clear that we need to be careful and discerning about the ways we speak and think about truth and the ways we suppose we understand who God is. St. Gregory of Nazianzus whom we remember today, spent his life thinking deeply about God’s nature and defending a particular way of understanding who God has revealed God’s self to be: namely, a trinity of persons ὁμοούσιονin one substance.
