Summary: The Trinity allows fellowship within the Godhead, and allows men to enter into real fellowship with God.
What’s today? Fathers Day.
This is Trinity Sunday. Today is the great patronal feast day of our Cathedral. And we of the Missionary Diocese of All Saints, we all share a common life, and we get to celebrate this feast day together because, in the diocese, we are one church. Isn’t that splendid? And this is the only Sunday on which
Now—and please be honest with me—do you think that the belief, the doctrine, the dogma, that God is Trinity really affects your life? How can something so difficult to understand, so remarkably strange and out there, really matter to me down here? Well, I’m going to tell you! Because God is Trinity, we have the opportunity to fellowship with Him. If He were otherwise, we could not.
Trinity is absolutely essential to the Christian faith. You cannot rightly bear the name Christian and deny the Trinity. Our forebears, our fathers and mothers in the faith, fought to protect this belief—they went into exile in foreign lands, suffered persecution at home, and even martyrdom—rather than allow it to become diluted with irrelevant matters or tainted with untruth. These saints who preserved the Faith, our Faith, your faith and mine, invested their lives into upholding a right view of the Trinity.
It’s only right, then, that we too be ready to defend and pass on whole and intact our Faith. We’re going to use some small terms (just five letters long) and some welterweight ideas (this is basic arithmetic).
Let’s talk about one. One plus…nothing…equals? One. One is singular, unity, simplicity, completeness, entirety, rationality. Okay, so do we understand one?
One plus one plus one equals? Three. Three is not singular, complementarity, complexity, harmony, cooperation, completeness. Three is—duh—more than one. So do we understand three better?
What is Trinity? This will be the only really heavy—as in difficult—part that we’ll go over. I promise it will be short. Can you hang with me for a minute and a half? I think you can. Trinity is Tri-unity. Three in one. The doctrine of the Trinity says that God is three persons (ὑpόstaseς) in one being (oὔsioς); three existences in one essence. The Father and the Son and the Holy Spirit are not three gods, but One God.
Trinity also means that God is One in three. God’s one essence, His essential being, the What of God, is expressed in the Father, Son, and Holy Spirit, the Who of God. The three are not the same who but are the same what. The Father and the Son are distinct persons and they exist without confusion as God, but they are united in the Godhead; they do not have a different god-ness, but are one. Is your head spinning? Well, we’re done with the hard stuff; it’s all downhill from here.
