The role of the Sabbath has been a subject of debate throughout Christian history, particularly concerning whether the seventh-day Sabbath remains binding for believers under the New Covenant. While the early church generally rejected the legalistic observance of the Jewish Sabbath, it did not abandon the concept of a day dedicated to worship and rest. Over time, Christian thought developed to emphasize Sunday, the Lord’s Day, as the primary day of worship, commemorating Christ’s resurrection. The Catholic Church, Protestant Reformers, and later Puritan and Reformed theologians all contributed to shaping the Christian understanding of Sabbath observance, leading to varying interpretations across different traditions.

Early Christian Views on the Sabbath

From the earliest days of Christianity, believers distinguished themselves from Jewish practices, including the observance of the seventh-day Sabbath. The church fathers interpreted the Sabbath as a spiritual principle rather than a legalistic command. Justin Martyr (c. 100–165), in Dialogue with Trypho (Chapter 12), argued that Christians observe a “perpetual Sabbath” in Christ rather than adhering to a specific day. He contended that true Sabbath-keeping was not about ceasing from labor on a particular day but about resting in Christ, who fulfilled the law (Schaff P. , 1885).

Tertullian (c. 155–220), in Against the Jews (Chapter 4), reinforced this perspective by emphasizing that the Sabbath command was temporary and had been fulfilled in Christ. He viewed the Mosaic Law, including the Sabbath, as a shadow of things to come, now replaced by the reality found in Jesus (Schaff P. , 1885). Similarly, Augustine (354–430), in City of God (Book 22, Chapter 30), saw the seventh-day rest as a symbol of the eternal rest believers would enjoy with God in the new creation (Schaff P. , 1887). These early theologians consistently interpreted the Sabbath typologically, seeing its ultimate fulfillment in Christ’s redemptive work rather than in the legalistic observance of a particular day.

The Medieval Church and the Shift to Sunday Worship

As Christianity grew and became more distinct from Judaism, Sunday—the day of Christ’s resurrection—gradually replaced the Jewish Sabbath as the primary day of Christian worship. The Catholic Church taught that the Sabbath rest described in Genesis 2:1-3 foreshadowed the Christian Sabbath, which was ultimately fulfilled in Christ. Rather than maintaining Saturday as the day of rest, the church emphasized Sunday as the “new Sabbath,” signifying the beginning of the new creation through Christ’s resurrection.

The authority to establish Sunday as the Christian day of worship was claimed by the church itself, based on apostolic tradition. This position was strongly reaffirmed at the Council of Trent (1545–1563), which declared that Sunday observance was a divine institution, rejecting Protestant arguments that it was merely a human tradition (Waterworth, 1563). Catholic theologians, such as Robert Bellarmine (1542–1621), defended this position by arguing that Genesis 2:1-3 pointed forward to Christ, whose resurrection fulfilled and transformed the Sabbath principle.

The Protestant Reformation and the Sabbath

With the Protestant Reformation came a rejection of the Catholic claim that the church had the authority to change the Sabbath. Reformers such as Martin Luther and John Calvin sought to return to Scripture as the sole authority on matters of doctrine and practice. Luther rejected the idea that the Sabbath was a binding law for Christians, viewing it as part of the ceremonial law given specifically to Israel rather than a universal command. In his Large Catechism, he argued that the third commandment (“Remember the Sabbath day, to keep it holy”) should be understood spiritually—as a call to devote time to God rather than a strict observance of a particular day. While Luther supported Sunday worship, he did so not because he believed it was divinely mandated but because it was a practical and established tradition within the Christian church (Schaff P. , 1876).

John Calvin similarly downplayed the idea that Sabbath observance was a binding legal requirement. He maintained that while a weekly day of rest and worship was beneficial, Sunday worship was not explicitly commanded in Scripture. Instead, he emphasized the moral and spiritual significance of setting aside time for worship, seeing the Sabbath principle as a means of fostering devotion to God rather than a rigid legal obligation (1845).

The Reformed and Puritan Sabbath Tradition

Although the early Reformers rejected the legalistic view of the Sabbath, later Reformed theologians, particularly the Puritans, reintroduced the idea that the Sabbath had ongoing moral significance. By the 17th century, Reformed theologians developed a covenantal theology of the Sabbath, arguing that Genesis 2:1-3 established a universal and perpetual obligation to set aside one day for worship and rest.

The Westminster Confession of Faith (1646) provided a detailed theological framework for this understanding, declaring that the Sabbath was instituted at creation and remained a moral obligation for all people (Westminster Assembly, 1646). According to this view, the seventh-day Sabbath was replaced by the Lord’s Day (Sunday) after Christ’s resurrection, but the principle of setting aside one day for worship and rest remained binding. The Puritans took this interpretation seriously, enforcing strict Sabbath observance in both England and the American colonies. They viewed Sabbath-breaking as a serious sin and sought to create societies where the Lord’s Day was honored through worship and rest, forbidding secular activities on Sundays.

Reformed theologians such as Francis Turretin (1623–1687) defended the moral obligation of Sabbath observance, teaching that Genesis 2:1-3 established a perpetual creation ordinance (Institutes of Elenctic Theology. Vol. 2, 1994). Jonathan Edwards (1703–1758) argued that the Sabbath foreshadowed the eternal rest of heaven and that strict Sabbath observance was essential for godly living (The Perpetuity and Change of the Sabbath, 1834). Other Puritan thinkers, such as John Owen (1616–1683) and Thomas Watson (1620–1686), also defended the ongoing obligation of the Sabbath, emphasizing that Christians should set apart one day each week for worship and reflection.

Catholic and Protestant Responses to Sabbatarianism

While some Protestant groups, such as the Seventh-Day Baptists, continued to advocate for Saturday Sabbath observance based on Genesis 2:1-3, the Catholic Church firmly rejected this view. Catholic theologians argued that the Apostles had transferred the day of worship to Sunday, and the church maintained its authority to establish Sunday as the new Sabbath.

Pope Urban VIII (1623–1644) and later Catholic theologians reaffirmed this position in response to Protestant Sabbatarian movements and the rise of Deism, which sought to diminish religious obligations altogether. Some Catholic scholars, such as Cornelius a Lapide (1567–1637), argued that Sunday represents the “eighth day” of the new creation—the dawn of redemption in Christ. Catholic theologians such as Robert Bellarmine continued to refute Protestant claims of legalistic Sabbath observance, emphasizing the spiritual fulfillment of the Sabbath in Christ.

Theological Justifications for Sunday Worship

Most contemporary theologians justify the transition from the seventh-day Sabbath to Sunday worship based on Christ’s resurrection. Henry Morris argues that the emphasis is on a “seventh” day, not necessarily Saturday, and that since Christ’s resurrection, most Christians have identified their weekly cycle around the first day of the week (The New Defender’s Study Bible, 1995, p. 15). Walton, in his Genesis commentary, supports this idea, comparing the shift from Saturday to Sunday with how Israel used the Sabbath to recall their deliverance from Egypt (Deuteronomy 5:15) (2001, p. 160). The New Testament also provides justification for Sunday worship, as passages such as Acts 2:1 and 1 Corinthians 16:1-2 indicate that the early church gathered on the first day of the week for worship and the breaking of bread.

Conclusion: The Sabbath and the Lord’s Day in Christian Theology

The transition from the seventh-day Sabbath to Sunday worship was a gradual process rooted in early Christian beliefs about Christ’s fulfillment of the law. While the Catholic Church emphasized its authority to designate Sunday as the Christian Sabbath, Protestant Reformers varied in their views, with some rejecting the Sabbath’s binding nature entirely and others, particularly within the Puritan and Reformed traditions, advocating for its ongoing moral obligation.

Despite these differences, Christians throughout history have agreed on the importance of setting aside time for worship and rest. Many theologians have argued that the ultimate fulfillment of the Sabbath is found in Christ Himself, who offers true spiritual rest to those who believe in Him (Hebrews 4:9-11).
