Sermon Study Guide: “Church 101 – What is the Church?”

Main Text: Various (Isaiah 28:16; 1 Corinthians 12; Ephesians 2; Matthew 16:18, 18:20)

Opening Reflection (Before Study)

The speaker begins by observing that when pastors say “the church,” they often mean the denominational structure, but Jesus defines it differently. What comes to your mind when you hear the word “church”? Is it a building, an organization, or the people?

Part 1: Biblical Foundations – What IS the Church?

Key Passages: Isaiah 28:16; 1 Corinthians 3:11; 1 Peter 2:4; Matthew 16:18; Matthew 18:20; John 7:37-39; Acts 19:32, 39 (re: Ecclesia)

Core Teaching:

  • The Church’s Foundation is Jesus Christ, not Peter or any human structure.

  • The Church’s Essence is spiritual, not structural. It exists wherever believers gather in Jesus’ name, with or without legal recognition, buildings, or hierarchy.

  • The Greek word Ecclesia means “called-out ones.” We are called out of the world to meet Christ and then sent back into the world on mission.

Discussion & Application Questions:

  1. Read Matthew 18:20. How does this verse challenge or expand your definition of “church”?

  2. The speaker stated: “The true church of Christ does not need a legal registration to be the church.” Do you agree? Why or why? What are the potential benefits and risks of this view?

  3. The Church is described as existing for the benefit of non-members (William Temple’s quote: “The only society that exists for the benefit of non-members”). How should this purpose reshape our church’s priorities and programs?

  4. Personal: In your daily life, are you more aware of being “called out” from the world or “sent back” into it? What would it look like to balance both this week?

Part 2: Three Biblical Metaphors for the Church

The sermon explores three rich images that define our identity and purpose.

A. The Church as a BODY (1 Corinthians 12:12-27)

Core Teaching:

  • Unity in Diversity: One body with many members, each with unique, God-given gifts.

  • Interdependence: No part is dispensable. We need each other.

  • Mutual Care: We share in each other’s sufferings and joys.

Discussion & Application Questions:

  1. Read 1 Corinthians 12:14-20. What “body part” do you feel like in your local church? Are you ever tempted to think, “Because I am not _____, I don’t belong”?

  2. The body is always changing. How has your local church body changed over the years? How can we embrace change while staying faithful to our mission?

  3. Personal: What spiritual gift or talent has God given you? Are you using it faithfully to build up the body, or is it “buried” (Matt. 25)? What is one step you can take this week to use it?

B. The Church as a TEMPLE (Ephesians 2:21; 1 Corinthians 3:16-17; 6:19-20)

Core Teaching:

  • Collective Temple (Naos): The Church is God’s dwelling place, the “holy of holies” where He meets with people.

  • Individual Temple: A believer’s body is the temple of the Holy Spirit.

  • Purity & Ownership: We are not our own; we were bought with a price. We must honor God with our bodies, avoiding sexual immorality and anything that defiles His temple.

Discussion & Application Questions:

  1. The speaker distinguished between hieron (temple complex) and naos (holy of holies). How should understanding the church as the naos (God’s dwelling) affect our worship services and community life?

  2. Read 1 Corinthians 6:19-20. The sermon applied this to sexual purity and conscience. Why is the body’s purity so connected to the Spirit’s presence? What other ways might we “defile” the temple of our body (e.g., diet, media, substances)?

  3. Personal: Reflect on Acts 16:6. The Holy Spirit guides in matters not explicitly covered in Scripture. Is there an area of your life (health, relationships, ethics) where you need to seek the Holy Spirit’s conviction for how to honor your body as His temple?

C. The Church as a BRIDE (Hosea 2:19; 2 Corinthians 11:2; Ephesians 5:25-27)

Core Teaching:

  • Covenant Relationship: God is married to His people. Christ is purifying His bride, the Church.

  • Purification Process: Christ sanctifies us “by the washing of water with the word” (daily Scripture).

  • Faithful Preparation: The Bride must remain faithful to Christ alone, rejecting worldly ideologies. We must actively prepare for the Bridegroom’s return.

Discussion & Application Questions:

  1. Read Ephesians 5:25-27. How does Christ cleanse and prepare His church? What is our role in this process?

  2. The speaker warned that the Bride “cannot go after other suitors,” like godless ideologies or putting human mandates above God’s commands. What are some modern “suitors” that pressure the church to be unfaithful?

  3. Personal: A bride is intentional in preparing for her wedding. Are you being intentional in your spiritual preparation for Christ’s return? Evaluate your daily engagement with Scripture. Is it a quick rinse or a thorough “washing”?

Part 3: Conclusion & Personal Application

Key Passage: Ephesians 4:1-6
Final Challenge: As we draw closer to Christ, we draw closer to each other. Our love for one another is the primary witness to the world.

Synthesis Questions:

  1. Review the three metaphors: BODY, TEMPLE, BRIDE. Which one resonates with you most right now, and why?

  2. The speaker gave a personal testimony of the church as his refuge, strength, and family. How has the body of Christ functioned in this way for you? When have you experienced it?

  3. Commitment: The sermon ended with a call to “let the blessings of God pass through you” and to allow others to minister to you. What is one practical way you can be a conduit of blessing to someone in your church this week? What is one area where you need to be vulnerable and receive ministry from others?

Closing Prayer Focus:
Pray for your local congregation to truly become a unified Body, a pure Temple, and a faithful Bride, demonstrating Christ’s love to a divided world.
