What Is the Church? Baptism and the Lord's Supper | Moheb Mina
"Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit."
— Matthew 28:19
There is a contradiction many live with in silence. People who have left their local churches and joined Christian organizations — yet when they come to marriage, they want it in a formal church. When they have children, they want them baptized in a formal church. When they fall sick or die, they want a formal church’s care. This contradiction reveals a deep truth: there are things that can only happen within the local church.
I. Baptism — Entry into the Body
Baptism is not merely a ritual — it is a public declaration that this person has died with Christ and risen with Him to new life.
But more important, in the context of our discussion, is this: every Christian tradition throughout history ties baptism inseparably to membership in a visible local church.
Notice the verb in Acts 2:41, immediately after baptism: “there were added.” Added — to what? To the community. In the New Testament, baptism and joining the community are two events that cannot be separated from each other.
The Testimony of Different Christian Traditions:
Eastern Orthodox: Baptism is “the door into the Church” — it has no meaning outside the community.
Coptic Orthodox: Baptism is immediately followed by the Sacrament of Chrismation and participation in the Eucharist — three inseparable sacraments of entry into the local body.
Reformed Tradition: Calvin stated: “Baptism ought not to be administered except in the Church, for it defines membership in the Church.”
Baptist Tradition: Baptism expresses personal faith prior to formal membership in the local church. But the membership itself remains necessary and obligatory.
There is not a single Christian tradition throughout history that conceives of the possibility of a person being baptized and then living their Christian life detached from an organized local community of believers.
II. The Lord’s Supper — An Ordinance for a Continuing Community
"For I received from the Lord what I also delivered to you, that the Lord Jesus on the night when he was betrayed took bread..."
— 1 Corinthians 11:23
The Lord’s Supper is an ordinance instituted by the Lord Jesus himself. But something occurs today that gives us pause: a group of young people gather together for a ministry or a camp for two months — then at the end they “break bread” and say: “We are celebrating the Lord’s Supper together.” Then the gathering disperses and perhaps they never meet again.
Three Reasons This Is a Real Problem:
First: The absence of ecclesial order — the Lord’s Supper requires ecclesial authority. Who plays the role of the pastor in preventing those who ought not to participate?
Second: The absence of continuity — “Let a person examine himself” (1 Cor. 11:28). This self-examination requires a community that knows the person and bears witness to his life — not a group that gathered for two months.
Third: A shift in meaning — the Lord’s Supper is transformed from a sacred ordinance declaring membership in the visible body of Christ, into a beautiful personal spiritual experience expressing the feelings of the moment.
Voices from Different Traditions:
“The Lord’s Supper is the moment in which the local church declares the identity of its members — who is inside the body and who is outside it.” — Jonathan Leeman
“Let no one hold the Eucharist or offer prayer apart from the bishop.” — Ignatius of Antioch, early second century
“The Holy Supper is the food of God’s children within God’s house — not a light meal shared by travelers on their way before they part.” — John Calvin
Conclusion: Why Does This Matter?
Practicing the breaking of bread and baptism outside the framework of a recognized local church does not merely confuse identity — it produces a real schism within the body of Christ.
The two ordinances together proclaim one truth: that the Christian life is a life in a body, in a community, in belonging. And this community has a name: the local church.
"So those who received his word were baptized, and there were added that day about three thousand souls."
— Acts 2:41
