The Church of Christ No. 3: Discerning The Church

Article 29 presses a question that cannot be shrugged off: what church ought believers join when every sect claims the name Christian? The abundance of churches in a place like DeMotte, the choices surrounding college, work, and marriage, and the fractured landscape left since the Reformation all make discernment necessary. Christ himself warns that not everyone who says, “Lord, Lord,” belongs to him. Wolves come in sheep’s clothing, and rotten onions do not become healthy because their outer layer looks fine.

Scripture gives the standard for this discernment. Personal taste, a nice personality, comfortable preaching, good music, cultural relevance, or a church website that says little about doctrine cannot tell anyone whether a church is true. The Word of God must be the litmus test. The central question is whether the gospel is present, whether Christ is proclaimed, and whether the church submits to his yoke.

The true church bears three marks. Pure preaching of the gospel stands first because the gospel founds the church. The pulpit must proclaim not merely a vague statement that Jesus died for sins, but the whole counsel of God, from Genesis through Revelation, with its call to faith, repentance, justification, sanctification, and holiness. The offense of the gospel cannot be traded for entertainment, stories, or “live your best life now” garbage.

The sacraments must also be administered purely, as Christ instituted them. Baptism and the Lord’s Supper are signs and seals of the gospel, and therefore they must lead sinners to Christ rather than to mystical idolatry, human choice, or manmade requirements. Rome’s additional sacraments, along with any practice that adds to or subtracts from Christ’s command, obscure the glory of Christ rather than display it.

Church discipline completes the marks of the true church. Discipline does not pretend that the church has everything together. Grace makes discipline necessary because sin is real, holiness matters, and believers need accountability. Faith shows itself in fleeing sin, pursuing righteousness, loving God and neighbor, and crucifying the flesh with its works.

The false church inverts these marks. False authority places tradition, popes, new revelations, or human ordinances above Scripture. False sacraments add to Christ’s institution or turn God’s covenant promise into a celebration of human decision. False churches also persecute those who rebuke greed, idolatry, and error. Matthew 7 therefore remains plain: healthy trees bear good fruit, diseased trees bear bad fruit, and Christ calls his people to look carefully at the fruit.

Key Takeaways

• 1. Discernment is a Christian responsibility Christ does not permit careless assumptions simply because a church uses Christian language. His warning about wolves in sheep’s clothing requires believers to make real judgments by God’s Word. Discernment is not proud fault-finding; it is humble obedience to Christ’s command to beware. [13:42]
• 2. The gospel must found the church The true church cannot treat the gospel as an occasional topic beneath entertainment, cultural relevance, or personal stories. The whole counsel of God reveals Christ and exposes the sin that sinners would rather avoid. A church without clear gospel preaching may still be busy, friendly, and impressive, but it has lost its center. [22:43]
• 3. Sacraments must lead sinners to Christ Baptism and the Lord’s Supper are not empty rituals, mystical techniques, or monuments to human choice. Christ gave these signs and seals to confirm his gospel and direct faith toward his finished work. Any practice that adds human requirements or removes Christ’s promise turns the soul away from the very Savior the sacrament proclaims. [30:21]
• 4. Holiness requires loving accountability Church discipline does not announce that Christians have arrived; it admits that sin still needs correction. Grace does not remove the call to flee sin, pursue righteousness, and crucify the flesh. A church that never notices absence, never confronts rebellion, and never calls people back has abandoned a vital work of love. [32:41]
• 5. Fruit exposes the church’s true root False doctrine eventually bears false fruit because a diseased tree cannot produce what is healthy. Christ calls believers to look beyond appearances, titles, and claims of unity toward the actual authority, worship, doctrine, and life of a church. The question is not merely whether a church looks Christian, but whether it belongs to Christ.

Bible Reading

Matthew 7:15–20
“Beware of false prophets, who come to you in sheep's clothing but inwardly are ravenous wolves. You will recognize them by their fruits. Are grapes gathered from thornbushes, or figs from thistles? So, every healthy tree bears good fruit, but the diseased tree bears bad fruit. A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. Thus you will recognize them by their fruits.” [13:15] [40:10] [40:26]

Matthew 7:21–23
“Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven. On that day many will say to me, ‘Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?’ And then will I declare to them, ‘I never knew you; depart from me, you workers of lawlessness.’” [11:09] [11:23]

Acts 20:27
“for I did not shrink from declaring to you the whole counsel of God.” [23:32]

Observation questions

1. In Matthew 7:15–20, what contrast does Jesus make between the outward appearance of false prophets and their true inward character?
2. What are the three marks used to recognize a true church, and how does each one keep Christ and his gospel at the center? [20:05]
3. According to Acts 20:27, what does Paul say he did not shrink from declaring, and how is that broader than simply saying, “Jesus died for sins”? [23:04]
4. What examples are given of things people may wrongly use as their standard for choosing a church instead of Scripture? [17:44]

Interpretation questions

1. Jesus says that people will be recognized by their fruit. What kinds of fruit should a believer look for when considering a church’s doctrine, worship, leadership, and life together? [40:19]
2. Why is clear preaching of the gospel treated as the first mark of a true church? What is lost when entertainment, personal stories, or cultural relevance replaces the faithful preaching of God’s Word? [20:36]
3. How do baptism and the Lord’s Supper function as signs and seals of the gospel? Why does adding human requirements to them direct attention away from Christ? [25:38]
4. Church discipline is meant for correcting faults, not displaying a church’s own righteousness. How can correction and accountability be an expression of grace and love rather than mere control? [31:30]

Application questions

1. When looking for a church—whether while traveling, moving, choosing a college, or considering a job—what questions could help you look beyond music, friendliness, convenience, and personal comfort toward the marks of a true church? [07:54]
2. Are there ways you are tempted to prefer preaching that leaves you comfortable rather than preaching that exposes sin and calls you to repentance? What does that temptation reveal about your heart? [18:13]
3. How regularly do you seek to know the “whole counsel of God” rather than only the passages or topics you naturally enjoy? What part of Scripture do you tend to avoid, and why? [23:47]
4. Baptism and the Lord’s Supper are meant to lead believers to Christ and his finished work. When you witness or receive these sacraments, what can help you remember God’s promise rather than focus mainly on human action or decision? [30:45]
5. Do you welcome brothers and sisters who know you well enough to ask about your spiritual life, absences, struggles, or ongoing sin? Where might you be tempted to avoid godly accountability? [32:33]
6. Faith shows itself in fleeing sin, pursuing righteousness, loving God and neighbor, and crucifying the flesh. What is one specific sin you need to flee or one concrete act of righteousness you need to pursue this week? [33:28]
7. Christ calls his people to beware of wolves while remaining humble. How can you speak truthfully about serious doctrinal error without becoming proud, harsh, or careless toward the people involved? [12:14]
