Many Christians claim that what matters most is a “personal relationship with Jesus.” This claim will be examined through Scripture, history, and reason. Scripture reveals God’s Word, history bears witness to how that Word has been lived and preserved in the Church, and reason is the natural faculty by which human beings recognize truth. These three must agree, because truth cannot contradict itself. Any claim about Christ that collapses under Scripture, history, or reason cannot be from God, who is the source of all three.
Things we must agree on:
- Many people hold many opinions about many things. But only one ultimately matters: the truth as God teaches it. Truth is not determined by popularity, sincerity, or personal comfort. If we reject God’s truth, we do not become free; we remain in darkness. Therefore, it is our duty to seek diligently what God has revealed above what you or I may prefer. Salvation is not secured by sincerity alone, but by conformity to the truth God has made known. Nothing is more important than this.
- I must seek the truth with humility, submitting myself to it rather than searching for ways to justify what I already believe. If I seek only confirmation, I can make even the Bible submit to me instead of submitting myself to it. Pride does not openly reject truth; it reshapes truth to avoid correction. Without humility, honesty, and integrity, I will never truly learn the truth, because truth does not yield to those who refuse to be changed by it.
- God’s revealed truth matters for salvation. What we believe is not a neutral matter. False belief endangers the soul because it distorts who God is, what He has done, and what He asks of us. If revealed truth did not matter, God would not reveal it. But God does reveal truth precisely because He desires to save. Therefore, contradictory teachings about God are not harmless differences of opinion; they are real dangers to souls. God is not the author of confusion, but of truth ordered toward salvation.
- This truth is so precious that Christ entrusted it to men He personally chose—the Apostles. They did not merely hear His words; they lived with Him, were formed by Him, and were commissioned by Him. They knew Him most intimately and understood His mission most clearly. The next most reliable witnesses are those whom the Apostles themselves taught and to whom they entrusted both this truth and the authority they received from Christ. These men are known as the Church Fathers. They did not learn the faith through speculation or private interpretation, but through direct instruction, lived discipleship, and continuity with the Apostolic mission.
- Scripture must always be interpreted in harmony with the rest of Scripture. If one passage appears to say one thing and another passage says something else, a faithful interpretation must account for both. To isolate verses we like while ignoring others is self-deception. It is no different from someone claiming the Bible commands killing simply because he refused to read the words “You shall not” that come before it. The Bible cannot contradict itself, because God cannot contradict Himself. Any interpretation that forces Scripture into contradiction is therefore false. Many serious errors arise precisely because a single verse is extracted, absolutized, and made the lens through which everything else is distorted.
- Reason, which often manifests in everyday life as what we call common sense, is a gift from God, given so that we may judge rightly and recognize truth. When our conclusions are unreasonable, it is a clear sign that we have embraced error. Reason comes from God; revelation comes from God; the laws of nature and all truth come from the same source. Therefore, they cannot compete with or contradict one another. Reason does not sit in judgment over God’s revelation, but it does judge our interpretations of that revelation. If an interpretation violates reason, it is not God’s truth that has failed, but our understanding of it.
What is the idea?
What this idea ultimately proposes is that church membership is optional so long as one claims to have a personal relationship with Jesus. According to this view, prayer may be entirely private, and worship may take place in any community—or none at all—provided one feels personally connected to Christ. In this framework, doctrine, sacramental life, and ecclesial authority are treated as secondary to personal experience.
Others hold a closely related view. They maintain that church membership does matter, but that the Church itself is not a visible or institutional reality. Instead, it is understood as a purely spiritual and invisible body, consisting of all who believe in Jesus in their hearts, regardless of visible unity, shared doctrine, or authoritative structure.
What does scripture say?
First, Jesus teaches plainly that one must be born of water and the Spirit in order to enter the Kingdom of God:
“Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God” (John 3:5)
This refers to Baptism. While some modern preachers dispute this meaning, Scripture itself leaves little room for ambiguity:
“Baptism now saves you” (1 Peter 3:21).
This understanding was not a later theological development. It is the teaching of the Apostles themselves:
“Repent, and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins” (Acts 2:38),
and again:
“All of us who have been baptized into Christ Jesus were baptized into His death” (Romans 6:3–4).
Those taught directly by the Apostles—the Church Fathers—were unanimous in understanding Baptism as the ordinary means by which one enters the Christian life. To reject this today is not merely to disagree with later tradition, but to claim that the earliest witnesses to Apostolic teaching fundamentally misunderstood it.
Second, Jesus declares with equal clarity:
“Unless you eat the flesh of the Son of Man and drink His blood, you have no life in you” (John 6:53).
This teaching caused scandal even among His disciples. Many found it hard to accept and walked away, yet Jesus did not retract or reinterpret His words (cf. John 6:60–67). The Apostles, however, remained, accepting His teaching as He spoke it. After the Resurrection, the disciples on the road to Emmaus “recognized Him in the breaking of the bread” (Luke 24:35), a phrase that the early Church consistently understood as referring to the Eucharist.
From the earliest days, Christians understood this breaking of the bread to be participation in Christ Himself:
“They devoted themselves to the apostles’ teaching and fellowship, to the breaking of the bread and the prayers” (Acts 2:42),
and as St. Paul writes,
“The cup of blessing which we bless, is it not a participation in the blood of Christ? The bread which we break, is it not a participation in the body of Christ?” (1 Corinthians 10:16).
While various interpretations are proposed today, they cannot all be true. Christ’s words do not carry multiple, contradictory meanings. They have one meaning, given by Christ, received by the Apostles, and handed on by the Church.
Related to this, Jesus commands:
“Do this in memory of Me” (Luke 22:19; 1 Corinthians 11:24–25).
The word translated as “memory” is the Greek anamnesis. This is not the language of mere mental recall. In Scripture, anamnesis is sacrificial language, drawn directly from the Old Testament, especially the Bread of the Presence, which was offered continually before God as a memorial sacrifice:
“You shall put pure frankincense on each row, that it may go with the bread as a memorial portion (anamnesis), an offering by fire to the Lord” (Leviticus 24:7; cf. Exodus 25:30).
Jesus’ command, therefore, is not simply an instruction to remember Him inwardly, but a command to perform a liturgical act. The Eucharist is inseparable from sacrifice and worship. It belongs to the public, communal, and priestly life of the Church—not to private devotion detached from the altar. As St. Paul affirms, this action proclaims the Lord’s death until He comes (cf. 1 Corinthians 11:26).
Jesus also gives clear instructions regarding authority and reconciliation within His community. He teaches that if a dispute cannot be resolved privately, it must be taken “to the Church,” and that refusal to listen even to the Church has consequences (Matthew 18:17). This instruction only makes sense if the Church is visible, identifiable, and authoritative. A purely invisible or spiritual Church cannot function as a final court of appeal. Christ assumes a Church that can be known, approached, and obeyed.
The practice of the Apostles confirms this visibility. They gathered on Sunday—the Lord’s Day—to break bread:
“On the first day of the week, when we were gathered together to break bread…” (Acts 20:7).
It was on this same day that the Holy Spirit descended upon the Church at Pentecost (Acts 2:1), and it was “on the Lord’s Day” that John received the Revelation (Revelation 1:10). This pattern is not incidental. It reflects the guidance of the Holy Spirit and the early Church’s understanding of ordered, communal worship centered on the Eucharist.
Finally, Christ Himself prayed for the unity of His Church:
“I do not pray for these only, but also for those who believe in Me through their word, that they may all be one” (John 17:20–21).
This unity is not a vague spiritual sentiment. If the Church is visible—as Scripture repeatedly shows—then her unity must also be visible. Persistent division, fragmentation, and contradictory teaching stand in direct tension with Christ’s prayer. A Church willed by Christ to be one cannot be reduced to a collection of disconnected believers without betraying His intention.
When Paul encountered Christ personally on the road to Damascus, his experience was unmistakably direct and supernatural. Yet even then, Paul was not told to act independently or to rely solely on his personal encounter. Instead, the Lord said to him:
“Rise and enter the city, and you will be told what you are to do” (Acts 9:6).
Paul later recounts the same instruction:
“And I said, ‘What shall I do, Lord?’ And the Lord said to me, ‘Rise, and go into Damascus, and there you will be told all that is appointed for you to do’” (Acts 22:10).
It is through Ananias—acting with the authority of the Church—that Paul receives instruction, baptism, and incorporation into the Christian community (cf. Acts 9:17–18). This makes a crucial point clear: even a genuine, personal encounter with Christ does not replace the authority Christ Himself established in His Church. Personal experience is ordered toward ecclesial obedience, not set against it.
This same visible and authoritative structure is displayed clearly in Acts 15. Faced with a serious doctrinal dispute, the Apostles and elders do not retreat into private interpretation. Instead, they assemble, deliberate, listen, and reach a binding decision for the whole Church. Their final statement is remarkable:
“It has seemed good to the Holy Spirit and to us” (Acts 15:28).
Here we see the Church acting as Christ intended—visible, united, authoritative, and guided by the Holy Spirit in her formal teaching. Doctrine is not decided by individual conviction but discerned within the Church Christ founded.
St. Paul later reflects on this reality when he calls the Church “the pillar and bulwark of the truth” (1 Timothy 3:15). Truth, in other words, is not left floating among private opinions. It is upheld, guarded, and proclaimed by the Church. Paul further describes the Church as the Body of Christ:
“Now you are the body of Christ and individually members of it” (1 Corinthians 12:27),
and again,
“He has put all things under His feet and has made Him the head over all things for the Church, which is His body” (Ephesians 1:22–23).
A body is not an abstract idea. It is visible, structured, and unified, with many members ordered toward one head. To speak of Christ’s Body as purely invisible is to empty the metaphor of its meaning.
Jesus Himself reinforces this visibility through His images of the Church. He describes His followers as “a city set on a hill,” adding that “it cannot be hidden” (Matthew 5:14). He also likens the Kingdom of God to a mustard seed—small at first, yet growing into a great tree in which the birds of the air make their nests (Matthew 13:31–32). These images presuppose visibility, growth, and universality. They make no sense if the Church is meant to be an invisible or purely spiritual association.
When Philip baptized new believers in Samaria, the work was not considered complete on his authority alone. Scripture tells us that when the Apostles in Jerusalem heard what had happened, they sent Peter and John, who prayed for the newly baptized and laid hands on them so that they might receive the Holy Spirit (Acts 8:14–17). This episode reveals several important realities at once. The Church is visible, because news of the baptisms reaches Jerusalem. She is hierarchical, because certain sacramental acts are reserved to the Apostles. And she is ordered and authoritative, because ministry is not interchangeable or self-appointed. From the beginning, the Church functioned as a structured body, not as a loose collection of independent believers.
Finally, Scripture shows the Church prefigured as the Kingdom of God in the Book of Daniel. Daniel describes a succession of earthly kingdoms—each real, historical, and visible—culminating in the Roman Empire. During the time of that final kingdom, Daniel foretells that God Himself would establish a new Kingdom:
“And in the days of those kings the God of heaven will set up a kingdom which shall never be destroyed, nor shall its sovereignty be left to another people; it shall break in pieces all these kingdoms and bring them to an end, and it shall stand for ever” (Daniel 2:44).
This Kingdom does not merely coexist alongside the others. It succeeds them in the order of history, outlasting and superseding them. Unlike every earthly empire before it, this Kingdom does not pass away, does not fragment, and is not replaced. The Roman Empire fell. The Kingdom Christ established did not. It remains, visible in history, continuous in authority, and enduring across the centuries.
Taken together, Scripture presents a single, coherent picture: Christ establishes a visible Kingdom, entrusts it to the Apostles, orders it hierarchically, guides it by the Holy Spirit, and promises that it will never be destroyed. This Kingdom is not an abstraction, nor a merely invisible reality, but a real, historical, and enduring presence in the world.
We cannot have only a personal relationship with Jesus apart from membership in the visible Kingdom He established. To claim otherwise would contradict the image of the Church presented throughout Scripture. It would require saying that not merely one Apostle misunderstood Jesus, but that all of them did. It would further require saying that the Church Fathers misunderstood the Apostles—and that all of them did. On this point, they are unanimous.
St. Ignatius of Antioch, a direct disciple of the Apostle John, writes at the beginning of the second century:
“Wherever the bishop appears, there let the multitude be; just as wherever Jesus Christ is, there is the Catholic Church.”
(Letter to the Smyrnaeans, 8)
For Ignatius, communion with Christ is inseparable from communion with the visible Church.
St. Irenaeus of Lyons, writing in the second century and taught by Polycarp—who himself was taught by the Apostle John—states plainly:
“It is within the power of all, therefore, in every Church, who may wish to see the truth, to contemplate clearly the tradition of the Apostles manifested throughout the whole world.”
(Against Heresies, 3.3.1)
Truth, for Irenaeus, is not discovered by private interpretation but by adherence to the visible Church founded by the Apostles.
St. Cyprian of Carthage, in the third century, leaves no ambiguity:
“He cannot have God for his Father who does not have the Church for his Mother.”
(On the Unity of the Church, 6)
A claimed relationship with God apart from the Church is, for Cyprian, a contradiction.
St. Augustine, writing in the fourth century, echoes the same conviction:
“I would not believe the Gospel unless moved by the authority of the Catholic Church.”
(Against the Letter of Mani, 5)
For Augustine, faith in Christ is inseparable from trust in the Church Christ established.
Reason itself confirms what Scripture and history testify. A purely personal relationship with Jesus, detached from His visible Kingdom, contradicts the consistent witness of the Apostles, the early Church, and the lived faith of Christians from the beginning.
The prophecy of the Church is fulfilled in the Catholic Church, founded by Christ. Scripture places the Apostolic mission at the heart of the Roman world. Peter writes from Rome—referred to symbolically as “Babylon” (1 Peter 5:13)—and Paul preaches there openly and without hindrance (Acts 28:30–31). From the earliest centuries, the Church recognized Rome as a central seat of Apostolic authority.
Membership in this Church is essential—but so is a living, personal relationship with Jesus Christ. These two realities cannot be separated, because the Church is the Body of Christ:
“Now you are the body of Christ and individually members of it” (1 Corinthians 12:27),
and God “has made Him the head over all things for the Church, which is His body” (Ephesians 1:22–23).
Membership alone does not suffice. Personal relationship alone does not suffice. Christ wills both. To separate what He has united is to misunderstand Him.
