1. John 17:22–23 (The Trinity and the Church), “The glory that you have given me I have given to them, that they may be one even as we are one, I in them and you in me, that they may become perfectly one, so that the world may know that you sent me and loved them even as you loved me.
This passage shows the close connection between the Holy Trinity and the Church.
2. Matthew 16:18–19 (Christ’s Promise to Build the Church; The Office of the Keys), “And I tell you, you are Peter, and on this rock I will build my church, and the gates of hell shall not prevail against it. I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.”
This passage is Christ’s great promise to build his Church and to entrust the Church with the office of the keys.
3. Romans 12:4–5 (Spiritual Gifts in the Church), “For as in one body we have many members, and the members do not all have the same function, so we, though many, are one body in Christ, and individually members one of another.”
This passage shows the unity, diversity, and interconnected nature of Christ’s members in his body, and is a key passage on spiritual gifts in the Church.
4. 1 Corinthians 10:16–17 (The Church Made One in the Eucharist), “The cup of blessing that we bless, is it not a participation in the blood of Christ? The bread that we break, is it not a participation in the body of Christ? Because there is one bread, we who are many are one body, for we all partake of the one bread.”
This passage shows that the Church is made one body by partaking of the body of Christ in the bread in the Lord’s Supper.
5. 1 Corinthians 12:12–13 (One Body, One Spirit): “For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ. For in one Spirit we were all baptized into one body—Jews or Greeks, slaves or free—and all were made to drink of one Spirit.”
6. Ephesians 1:22–23 (Totus Christus), “And he put all things under his feet and gave him as head over all things to the church, which is his body, the fullness of him who fills all in all.”
This is a key passage for the doctrine of Totus Christus (the “whole Christ”).
7. Ephesians 2:19–22 (God’s Temple): “So then you are no longer strangers and aliens, but you are fellow citizens with the saints and members of the household of God, built on the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone, in whom the whole structure, being joined together, grows into a holy temple in the Lord. In him you also are being built together into a dwelling place for God by the Spirit.”
8. Ephesians 4:11–16 (A Well-Functioning Body Grows Strong), “And he gave the apostles, the prophets, the evangelists, the shepherds and teachers, to equip the saints for the work of ministry, for building up the body of Christ, until we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ, so that we may no longer be children, tossed to and fro by the waves and carried about by every wind of doctrine, by human cunning, by craftiness in deceitful schemes. Rather, speaking the truth in love, we are to grow up in every way into him who is the head, into Christ, from whom the whole body, joined and held together by every joint with which it is equipped, when each part is working properly, makes the body grow so that it builds itself up in love.”
This passage shows the importance of church leaders for equipping the body, and teaches that a well-functioning body will grow strong.
9. Ephesians 5:22–32 (The Bride of Christ), “Wives, submit to your own husbands, as to the Lord. For the husband is the head of the wife even as Christ is the head of the church, his body, and is himself its Savior. Now as the church submits to Christ, so also wives should submit in everything to their husbands. Husbands, love your wives, as Christ loved the church and gave himself up for her, that he might sanctify her, having cleansed her by the washing of water with the word, so that he might present the church to himself in splendor, without spot or wrinkle or any such thing, that she might be holy and without blemish. In the same way husbands should love their wives as their own bodies. He who loves his wife loves himself. For no one ever hated his own flesh, but nourishes and cherishes it, just as Christ does the church, because we are members of his body. “Therefore a man shall leave his father and mother and hold fast to his wife, and the two shall become one flesh.” This mystery is profound, and I am saying that it refers to Christ and the church.”
This beautiful passage teaches that the Church is the bride of Christ.
10. 1 Peter 2:4–12 (The New Israel), “As you come to him, a living stone rejected by men but in the sight of God chosen and precious, you yourselves like living stones are being built up as a spiritual house, to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ. For it stands in Scripture: “Behold, I am laying in Zion a stone, a cornerstone chosen and precious, and whoever believes in him will not be put to shame.” So the honor is for you who believe, but for those who do not believe, “The stone that the builders rejected has become the cornerstone,” and “A stone of stumbling, and a rock of offense.” They stumble because they disobey the word, as they were destined to do. But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light. Once you were not a people, but now you are God’s people; once you had not received mercy, but now you have received mercy. Beloved, I urge you as sojourners and exiles to abstain from the passions of the flesh, which wage war against your soul. Keep your conduct among the Gentiles honorable, so that when they speak against you as evildoers, they may see your good deeds and glorify God on the day of visitation.”
This passage views the Church as the new Israel.
EXTRA: 1 John 1:7, “But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin.”
This passage highlights our fellowship with one another in the body of Christ.
