not the same as the Early Christians.
The Early Christians believed that the baptism commanded in Matthew 28:18–20 was a regenerative act that forgave sins and restored the individual to new life in God.
Baptism in the Early Church
Early Christian writings consistently portray baptism as essential for the forgiveness of sins. The Didache (c. AD 50–70) prescribes Trinitarian baptism “in the name of the Father, and of the Son, and of the Holy Spirit,” indicating a formal, sacramental practice. The Shepherd of Hermas (c. AD 80) explicitly teaches that baptism is the one time when “the remission of our former sins” is granted. Justin Martyr (c. AD 151) describes baptism as a “regeneration” in which believers are “born again” through water, affirming its role in entering the kingdom of heaven.
1. Clement of Rome (c. AD 96)
Clement was a contemporary of the Apostles and is often cited as the strongest early witness for justification by faith.
"And we, too, being called by His will in Christ Jesus, are not justified through ourselves, nor through our own wisdom, or understanding, or godliness, or works which we have wrought in holiness of heart; but through faith, whereby the Almighty God has justified all men from the beginning; to whom be glory for ever and ever. Amen." (Letter to the Corinthians, Chapter 32)
2. Ignatius of Antioch (c. AD 35–107)
Writing on his way to martyrdom, Ignatius identifies Christ’s work as the sole ground of his hope.
"His cross, and His death, and His resurrection, and the faith which is through Him, are my unpolluted monuments; and by these I desire, through your prayers, to be justified." (Letter to the Philadelphians, Chapter 8)
3. Polycarp of Smyrna (c. AD 69–155)
Polycarp was a disciple of the Apostle John. His language echoes the Pauline epistles closely.
"Knowing that 'by grace ye are saved, not of works,' but by the will of God through Jesus Christ... If we do His will, we shall walk in His commandments... believing in Him who raised up our Lord Jesus Christ from the dead." (Letter to the Philippians, Chapter 1)
4. The Epistle to Diognetus (c. AD 130)
This anonymous work is often considered one of the most "Protestant-sounding" texts of the early church because of its clear description of the "sweet exchange."
"He gave His own Son as a ransom for us... For what else could cover our sins but His righteousness? In whom was it possible for us, the lawless and ungodly, to be justified, except in the Son of God alone? O sweet exchange! O unsearchable operation!" (Chapter 9)
5. Ambrose of Milan (c. AD 339–397)
Ambrose was a mentor to St. Augustine and was very explicit about the legal (forensic) nature of justification.
"I will not glory because I am righteous, but I will glory because I am redeemed. I will not glory because I am free from sins, but I will glory because my sins are forgiven me. I will not glory because I have done good nor because anyone has done good to me, but because Christ is my advocate with the Father." (On the Benefits of Death)
6. John Chrysostom (c. AD 347–407)
Known as "Golden Mouthed" for his preaching, Chrysostom often argued that faith provides what the law cannot.
"For you have not achieved this [salvation] by any works of yours, but by faith only did you come to be saved. You did not give anything at all, but rather you received... For God’s grace is such that it saves by faith alone." (Homily on Ephesians)
Scriptural Basis
Jesus’ command in Matthew 28:19–20—“baptizing them in the name of the Father and of the Son and of the Holy Spirit”—was understood by early Christians as the foundational act of discipleship. This is reinforced by Peter’s preaching in Acts 2:38: “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins.” 1 Peter 3:21 further states, “Baptism… now saves you,” not as a removal of physical dirt but as an appeal to God for a good conscience through Christ’s resurrection.
1. Tertullian (c. AD 155–220)
Tertullian is famous for his legalistic view of the faith, yet he provides one of the clearest statements on faith being the true "source" of cleansing, with baptism acting as the "seal."
"We are not washed in order that we may cease sinning, but because we have ceased, since we are already washed in heart. For the first baptism of the learner is a perfect fear; thenceforward, in so far as you have a sense of the Lord, you provide yourself with a spirit of repentance... [Baptism] is the seal of faith." (On Repentance, 6)
2. Origen (c. AD 184–253)
Origen was known for his allegorical interpretations. He often cautioned that the water itself did nothing if the internal disposition of the person was not correct.
"Not everyone who is washed with water is immediately washed by the Holy Spirit... the washing with water is a symbol of the purification of the soul washed from every stain of sin." (Homilies on Ezekiel)
3. Cyril of Jerusalem (c. AD 313–386)
Though Cyril is often quoted in support of baptismal regeneration, he gave a famous warning to his catechumens (students) that the water could be "empty" without faith.
"If your intention is wrong, the water will receive you, but the Spirit will not accept you... if you are a hypocrite, the water washes your body, but the Spirit does not enlighten your mind. The water is a type, but the reality is the Holy Spirit." (Procatechesis, 4)
Theological Consensus
The early Church viewed baptism not as a mere symbol but as a spiritual reality through which God applies Christ’s sacrifice. This belief persisted across traditions, including Catholic, Orthodox, and Reformed thought, and was central to the Church’s understanding of salvation.
Thus, early Christians saw Matthew 28:18–20 not just as a command to be followed, but as the divine means by which sins were washed away and new life in Christ was initiated. (Summary by Brave AI)
