Happy Sunday! Yes ... a bonus post for you. I couldn’t pass up the last chance I’ll have for months to highlight a special day in the church calendar. It’s not as sexy a day as Pentecost (last week), so I won’t bother with a poll this time. If your church didn’t acknowledge Pentecost, no way will they know it’s Trinity Sunday.
What is Trinity Sunday all about?
This Sunday marks the end of the annual cycle marking the life of Christ. It began with Advent and Christmas when the Father sent the Son, and peaked at the Ascension when the Son returned to the Father. Following the timeframe set in Scripture, ten days later we celebrated the arrival of the Spirit. So now we stop to mark the triune nature of our God.
Admittedly, three Persons in one God is a metaphysical mystery. So we do not try to explain how it works, only to worship him and affirm that Scripture attests to his three-fold nature many times.
The Trinity defined: God is eternally one essence with three persons. The Father is not the Son who is not the Holy Spirit who is not the Father. But the Father is God, the Son is God, and the Spirit is God—eternally.
The three Persons are distinct yet unified and equal. C.S. Lewis describes the Trinity as “a dynamic, pulsating activity, a life, almost a kind of drama. Almost, if you will not think me irreverent, a kind of dance.” (Mere Christianity) He is love overflowing in relationship.
Knowing our God is Trinity and eternal ought give us the foundation on which we stand to face the realities of our world. No other ruler will live forever, no empire has stood or will stand victorious over the kingdom of God. I encourage you to read Esau McCaulley’s essay “Yes, Protest. But Worship First” to see the connection between our theology of God and our perspective on current events.
He is Father.
Psalm 89:26 “He will call to me, ‘You are my Father, my God, the rock of my salvation.’”
Malachi 2:10 “Don’t all of us have one Father? Didn’t one God create us?”
John 20:17 “… go to my brothers and tell them that I am ascending to my Father and your Father, to my God and your God.”
He is Son.
Luke 1:35 “The angel replied to her, ‘The Holy Spirit will come upon you, and the power of the Most High will overshadow you. Therefore, the holy one to be born will be called the Son of God.’”
Matthew 16:16 “Simon Peter answered, ‘You are the Messiah, the Son of the living God.’”
He is Spirit.
Genesis 1:2 “Now the earth was formless and empty, darkness covered the surface of the watery depths, and the Spirit of God was hovering over the surface of the waters.”
Psalm 51:11 “Do not banish me from your presence or take your Holy Spirit from me.”
John 4:24 “God is spirit, and those who worship him must worship in Spirit and in truth.”
Romans 15:13 “Now may the God of hope fill you with all joy and peace as you believe so that you may overflow with hope by the power of the Holy Spirit.”

Ok, so they’ll be imperfect. All I can say is, please do not succumb to the temptation to use an analogy. No shamrocks, eggs, apples, modes of water, etc. They don’t work. Instead, let some experts help.
