The early church in the second and third centuries was a vibrant, evolving community that established a rich tapestry of liturgical practices, moral teachings, and eschatological hopes. From rigorous catechetical instruction before baptism to the communal worship on Sunday and the formulation of a distinct Christian identity in daily life, these formative centuries set the stage for the development of Christian tradition.
Christian Initiation
Christian initiation in the early third century was a carefully structured process that went far beyond the simple procedures recorded in the New Testament. By this time, the ritual of baptism had been elaborated into a comprehensive program of instruction and moral examination designed to ensure that only those truly committed to the faith were admitted to the community.
A lengthy period of catechesis preceded baptism. Candidates underwent years of instruction in Christian doctrine and moral behavior, with the Apostolic Tradition suggesting as much as three years of preparation. The emphasis was always on conduct—candidates were judged not by the length of their instruction, but by the transformation evident in their lives. Slaves were taught to serve their masters faithfully, married couples were urged to maintain marital fidelity, and unmarried persons were exhorted to avoid sexual immorality. Professions or behaviors considered inherently contrary to Christian ethics—such as involvement in prostitution, pagan theatrical performances, gladiatorial combat, and certain forms of idolatry—could result in disqualification from baptism.
The initiation process was not only about learning doctrine; it was a rigorous moral examination. For instance, individuals engaged in professions like sculpting or painting were expected to renounce any involvement in creating idols. Even educators, whose role was to transmit the literature of pagan culture, were required to abandon this task if it conflicted with their new Christian calling. Soldiers, too, were faced with ethical choices: those desiring to join the army were rejected if they were unable to renounce violence and the oath of military service.
The actual baptismal ceremony was rich with symbolic actions. Preparations began on the Thursday before Easter—an auspicious time reflecting the connection between baptism and Christ’s own passion and resurrection. This period involved fasting, prayer, confession of sins, and the reading of Scripture. An important aspect of the ceremony was the exorcism of demons, which underscored the belief that baptism was a decisive break from the power of evil.
On the morning of baptism, the administrator of the rite would pray for the sanctifying power of the Holy Spirit to descend upon the water. Candidates were baptized by triple immersion—a practice attested by Tertullian and still observed in Eastern Orthodox traditions today. The procedure was highly formalized: children, men, and women were baptized separately, ensuring that the sacred act was conducted with appropriate solemnity. Before immersion, the candidates made a public renunciation of “the Devil, his pomp, and his angels,” declaring their repentance and commitment to a new life in Christ.
As each candidate was immersed, the bishop or presbyter would lay a hand on their head and ask a series of questions: “Do you believe in God the Father Almighty?” “Do you believe in Christ Jesus the Son of God…?” and “Do you believe in the Holy Spirit, the holy church, and the resurrection of the flesh?” With each confession of faith, the candidate was symbolically drawn deeper into the mystery of salvation. Following the immersion, an anointing with the oil of thanksgiving and another imposition of hands underscored the reception of the Holy Spirit and confirmed the individual’s place in the assembly.
In special circumstances—such as when a candidate was on their sickbed or when water was scarce—alternative methods of baptism were accepted. The Didache, an early Christian manual, permitted the pouring of water three times over the head in the absence of running water. Although some debated the legitimacy of these “sickbed baptisms,” theologians like Cyprian argued that as long as the act was performed within the community and in the presence of sincere faith, the sacramental grace was not diminished.
Infant baptism, too, began to emerge during this period, though it was not routine. Initially reserved for cases where death was imminent, infant baptism later became more common as a means of ensuring that even the youngest were brought into the covenant of faith. While Tertullian expressed reservations, by the mid-third century the practice found robust support from figures like Cyprian.
Christian Assemblies
From its earliest days, the Christian community recognized the importance of gathering together for worship, instruction, and the sharing of the sacraments. Sunday, known as the “Lord’s Day,” emerged as the principal day of assembly, commemorating the resurrection of Jesus. This day of worship was distinct from the Jewish Sabbath, and early Christians made a clear separation between the two.
The Roman governor Pliny documented that Christians met before sunrise on a fixed day each week—a practice necessitated by the fact that Sunday was not an official holiday under Roman rule. Meetings often began with communal prayers, Scripture readings, and a sermon that expounded on the teachings of the apostles and prophets. Justin Martyr’s description of the Sunday service gives us a clear picture: a structured gathering that included readings, a homily, the celebration of the Eucharist, and a communal meal.
The Eucharist, or “thanksgiving,” held a central place in Christian worship. It was not merely a ritual meal, but a profound act of remembrance, fellowship, and eschatological hope. The bread and wine, often mixed with water, were believed to be the means by which the faithful received the spiritual nourishment necessary for life in Christ. This rite of communion was also a powerful statement of unity—baptized believers who shared in the Eucharist were bound together in a common faith and hope for resurrection.
Over time, the Sunday assemblies became more organized. Initially held in the homes of affluent members, these gatherings eventually led to the renting or purchasing of dedicated meeting spaces. By the end of the third century, some communities had built their own halls for worship, signifying the increasing stability and identity of the Christian church.
The liturgical structure of the assembly began to develop distinct parts. One segment was devoted to the proclamation and teaching of the Word—a time for instruction open to all who wished to learn. The second part centered on the Eucharist, a sacred meal reserved for those who had been baptized and were in good standing with the community. Hymns, psalms, and prayers punctuated the service, and contributions were collected to assist the needy, reflecting the communal commitment to charity.
Christian apologists like Justin Martyr and Irenaeus contrasted the Christian assembly with pagan practices by highlighting the absence of temples, altars, and material sacrifices in their worship. Instead, the focus was on the transformation of the self through faith, the communal sharing of life, and the anticipation of eternal reward.
Christian Daily Life
Beyond the formal gatherings on Sunday, early Christians embraced a comprehensive way of life that integrated regular prayer, fasting, and moral discipline into their daily routines. The Didache, a prominent early Christian document, prescribed fasting on Wednesdays and Fridays—a marked contrast to the Jewish custom of fasting on different days. This regular fasting, along with the mandated recitation of the Lord’s Prayer multiple times a day, underscored the importance of continual spiritual vigilance.
Daily life for early Christians was punctuated by both communal and private practices of prayer. Some communities met at specific times during the day—often at dawn, mid-day, and in the evening—to read Scripture and offer prayers. Other sources, such as Clement of Alexandria and Tertullian, suggest even more frequent intervals of prayer, reflecting a deep-seated commitment to living a life that was in constant communication with God.
Moral teaching was at the heart of the Christian way of life. Drawing on the “Two Ways” doctrine found in the Didache and Barnabas, early Christian ethics expanded on the Ten Commandments, applying them not only to external actions but also to the attitudes of the heart. The Sermon on the Mount, with its radical call to love one’s enemies and reject retaliation, became a cornerstone of Christian morality. Apologists like the author of the Epistle to Diognetus depicted Christians as living “in the world, but not of the world”—exemplifying honesty in business, sexual purity, family solidarity, and a deep concern for the poor and oppressed.
This distinctive way of life, characterized by its moral rigor and practical compassion, also proved to be a powerful witness to pagan society. The courage with which Christians faced persecution, even to the point of martyrdom, inspired admiration among non-believers. The steadfast commitment to ethical living and the willingness to suffer for the sake of faith demonstrated that Christian virtue was more than mere theory—it was a lived reality.
Charity played a crucial role in daily Christian practice. The contributions collected during Sunday assemblies were used to support a wide range of social needs: care for the sick, assistance for the elderly, support for widows and orphans, and even provisions for prisoners and travelers. This commitment to mutual care not only helped the vulnerable but also fostered a profound sense of community and shared responsibility.
For many Christians, participation in military service presented a moral dilemma. While some believers did serve in the army by the end of the second century, influential Christian thinkers—such as Tertullian, Hippolytus, and Origen—argued against active involvement in war. They contended that the call to non-violence and the rejection of killing were integral to the Christian witness. This tension between civic duty and spiritual commitment would continue to provoke debate throughout the centuries.
Christian Women
Although the surviving literature of early Christianity often focuses on male leaders, women played a vital and dynamic role in the life of the church. Early Christian texts, while sometimes limited in detail, provide evidence that women were active participants in both the domestic and public spheres of Christian life.
Women in the early church were primarily recognized in their traditional roles as wives and mothers. They were expected to manage their households with order, educate their children in the fear of God, and exhibit steadfast love and fidelity toward their husbands. Yet, beyond these roles, many women embraced a life of celibacy, whether as virgins who never married or widows who chose not to remarry. By the third century, small communities of celibate women began to form, living together in a spirit of mutual support and dedication to a higher calling.
Some of the most celebrated martyrs of the early church were women—figures like Blandina at Lyons and Perpetua at Carthage stand out for their extraordinary courage in the face of persecution. Their stories not only inspired fellow believers but also underscored the egalitarian nature of the Christian message, where faith and sacrifice transcended gender.
Women also played an important role in the missionary work of the early church. They often accompanied apostles and evangelists on journeys, working behind the scenes to nurture new converts and support the expansion of the faith. The apocryphal Acts of Paul, for example, highlights the role of Thecla—a woman who became a revered saint in Asia Minor—whose life of piety and perseverance resonated with early Christian communities.
In the context of church leadership, women were sometimes appointed to roles such as deaconesses, particularly to assist with the baptism of other women and to support female members of the congregation. While mainstream New Testament teachings generally reserved positions of elder or public teacher for men, the practical needs of the growing church allowed for women to exercise significant influence in their spheres of responsibility.

Christian Hope
At the heart of early Christian belief was an unwavering hope in the future—a hope that sustained believers through persecution, hardship, and the uncertainties of life. Two distinct yet related patterns of eschatological hope emerged in these formative centuries: chiliasm and non-chiliasm.
Chiliasm, or the belief in a literal thousand-year reign of Christ on earth, was rooted in apocalyptic Jewish traditions. Proponents of this view held that the righteous would be resurrected at Christ’s return and participate in an earthly, messianic kingdom centered in Jerusalem. The idea of a millennial kingdom served not only as a counterpoint to various heretical views but also as a robust polemic against groups like the Marcionites and Gnostics. Irenaeus, for instance, integrated the millennium into his theology, interpreting it as a time during which resurrected bodies were prepared for the heavenly vision of God. Tertullian even posited that martyrs, by their exceptional faith, bypassed the intermediate state and were granted immediate access to the presence of Christ.
In contrast, a non-chiliastic form of eschatology held that the kingdom of God was not to be understood as an earthly realm but rather as a heavenly reality. According to this view, the righteous were already participants in the heavenly kingdom—residing in paradise with Christ—without the need for an interim period on earth. Many early Christian writers, including Hermas, Polycarp, and Origen, supported this perspective, emphasizing that the resurrection of the body would occur only at the final judgment, culminating in an eternal division between heaven and hell.
Both eschatological frameworks shared the core belief in the bodily resurrection—a point of sharp contrast with some Gnostic views, which often focused on the resurrection of the soul rather than the flesh. The promise of eternal life and the expectation of a future, definitive judgment provided the early Christians with hope and the strength to endure suffering. In times of persecution, this eschatological conviction was more than a doctrine—it was a lifeline that connected believers with a transcendent future and reinforced their identity as citizens of God’s kingdom.
The practical outworking of this hope could even be seen in the burial practices of the early church. While Christians initially shared burial grounds with pagans, the eventual acquisition of sites like the catacombs of Callistus in Rome symbolized a growing awareness of the sacredness of death as a passage into eternal life. Inscriptions, images, and symbols placed in these burial sites served as tangible expressions of the Christian hope—a hope that transcended the present and promised resurrection and renewal.
Conclusion
Church life in the second and third centuries was a period of dynamic growth, rigorous discipline, and profound spiritual hope. The detailed catechetical process of initiation ensured that new members were not only knowledgeable about the faith but also transformed by it. Regular assemblies on the Lord’s Day provided a structured environment for worship, instruction, and the communal sharing of the Eucharist, while the daily practices of prayer, fasting, and moral living distinguished Christians from the surrounding pagan society.
Women, though less frequently mentioned in surviving texts, played indispensable roles in nurturing the community, supporting the missionary effort, and exemplifying the values of faith and sacrifice. And overarching all these practices was a robust eschatological hope—whether viewed through the lens of chiliasm or its non-literal counterpart—that sustained the believers through trials and inspired them to live lives marked by charity, honesty, and unwavering commitment to Christ.
The legacy of these early practices can still be felt today. The rituals of baptism, the structure of communal worship, the emphasis on moral conduct, and the hope of resurrection remain central to Christian identity. By looking back at how early Christians initiated their members, organized their assemblies, and lived out their faith, modern believers can gain insights into the enduring values that continue to shape the church.
