Trinity Sunday // Revd Sophie Raeside // 31st May 2026

Trinity Sunday sets the agenda: one God, three persons, and a life patterned by that God. The doctrine of the Trinity states that God the Father, God the Son, and God the Holy Spirit are each fully God, all equally divine, of equal status, and yet truly distinct. A pop-culture picture helps the intuition land: like one Spider Man showing up as three distinct Peter Parkers in one multiverse story, the confession speaks of one God in three persons. The image is only a hint, but it makes space for saying both one and three without collapse. Perichoresis then gives language for the life within God. As Augustine puts it, each are in each, and all in each, and each in all, and all are one. The communion of Father, Son, and Spirit is total, without confusion and without rivalry.

Matthew’s baptismal formula names this reality without spelling it out. Jesus sends his disciples to the nations in the single Name of the Father and of the Son and of the Holy Spirit. The text gives the grammar. The church, over centuries, found its words. As McGrath notes, the confession was uncovered rather than invented.

Relationship with the Trinity follows from who God is. The Father reframes fatherhood from the top down, not from human experience up. The Father is present, patient, loving, kind, constant, not a projection of mixed earthly memories but the living source who heals them. The Son makes God relatable in flesh and blood. Jesus knows laughter, tears, abuse, rejection, death, and he bears sin to open the way into fellowship. The Spirit then comes alongside. Parakletos means counselor, advocate, comforter, helper, encourager. God meets people by his Spirit, not as an idea but as the One called alongside.

The Great Commission locates ministry in that Name. Jesus commands going, discipling, baptizing, teaching. The call belongs to every disciple, not only to staff or titles. A missional life means intentionally sharing Christ’s love wherever and with whoever one finds oneself. Ordinary acts count: an invitation to a service, a promise to pray, a quiet word in grief, a children’s Bible at bedtime. Results are God’s to keep. Faithfulness lowers the bar and raises availability. God often works through a friend like Emily who is open, unafraid of questions, willing to pray, and ready to walk with someone to church and Alpha. The triune God relates, then invites, then sends, and then stays present in the going.

Key Takeaways

• 1. One God, three equal persons The confession refuses both confusion and division. Father, Son, and Spirit are each fully God, equal in glory and worth, yet irreducibly distinct. The church did not invent this; Scripture’s grammar pressed the church to say it. The Name named in baptism guards the unity and the threefoldness. [04:41]
• 2. Perichoresis opens relational life If God’s life is communion, salvation is participation in that communion. Perichoresis is not a puzzle to solve but a home to enter, where the other is never threat but gift. Union without fusion and distinction without distance become the pattern of healed relationships. [05:59]
• 3. Know the Father, Son, Spirit The Father redefines fatherhood by his constancy and kindness. The Son dignifies human pain by sharing it and bearing it. The Spirit meets believers as advocate and helper, bringing the nearness of God into ordinary hours. [12:06]
• 4. Ordinary faithfulness advances mission The Great Commission runs on small obediences in real places. Invitations, prayers offered in passing, a word of hope in grief, and the long patience of parenting all become seed. The Spirit handles the harvest; disciples handle availability. [14:07]

1. What three distinct roles or titles of the Holy Spirit (Parakletos) are mentioned in the sermon, and how do they describe His work? [10:44]
2. How does the sermon use the Spider-Man multiverse analogy to explain the Trinity? [02:29]
3. What does the term perichoresis mean, and how does it describe the relationship within the Trinity? [05:59]
4. According to the sermon, what are three ordinary, everyday acts named as examples of living missionally? [14:40]

1. Why might Jesus specifically command baptism “in the name of the Father and of the Son and of the Holy Spirit” (Matthew 28:19) instead of using a simpler formula?
2. The sermon states that perichoresis (mutual indwelling of the Trinity) is “not a puzzle to solve but a home to enter.” How might this truth reshape how we view conflict or disconnection in human relationships?
3. The Holy Spirit is called “one called alongside” (Parakletos). What does this imply about how God meets people in their daily struggles compared to abstract religious ideas? [10:44]
4. The sermon says, “Results are God’s to keep. Faithfulness lowers the bar and raises availability.” Why might focusing on “availability” rather than outcomes be both freeing and challenging for believers?

1. The Father is described as “present, patient, loving, kind, constant” and distinct from flawed human examples. How might someone begin to heal distorted views of God if their earthly father was absent or hurtful? [09:23]
2. Jesus “knows laughter, tears, abuse, rejection, death” in His humanity. What current struggle or emotion in your life could you intentionally bring to Him this week, trusting He understands?
3. The Spirit is called a “helper” and “advocate.” What practical step could you take to rely on Him more in a situation where you feel overwhelmed or alone?
4. The sermon gives examples like inviting someone to a service, praying for a coworker, or sharing hope in grief. Which of these “ordinary acts” feels most doable for you in the next seven days? What would it look like to try it? [14:40]
5. How could you intentionally foster “union without fusion and distinction without distance” (like the Trinity’s perichoresis) in a strained relationship or community?
6. The Great Commission is framed as “small obediences in real places.” What “real place” (e.g., workplace, family, gym) has God already placed you in to share His love? What’s one way to lean into that opportunity?
