What is the significance of Sunday 1 in the journey?

The First Day as a Cornerstone of the Journey

From earliest times recorded in the New Testament, the day now known as Sunday (the first day of the week) has held particular significance. Whether viewed through the lens of historical worship practices or by considering pivotal events such as the Resurrection, this “first day” stands as an enduring symbol of new beginnings, community gathering, and spiritual renewal. The journey of faith often hinges upon understanding why Sunday, or “Day One,” carries weight for believers seeking to grow in devotion and commitment.


Biblical Foundations of the First Day

Throughout Scripture, the first day of the week emerges as a day marking points of transition. In Genesis, the first day marks the beginning of God’s creative work. Creation proceeds quickly—“God said, ‘Let there be light,’ and there was light” (Genesis 1:3)—establishing that amazing changes can commence on the first day.

In the teachings of Christ’s followers, this same day finds new significance as it becomes associated with key events. Early Christians note that it was on the first day of the week that believers gathered to break bread and listen to teaching (Acts 20:7). Additionally, the apostle Paul instructs churches to set aside contributions on the first day (1 Corinthians 16:2). Such references demonstrate a shift in focus, suggesting that this day bore extraordinary importance from the outset of the church’s formation.


Sunday and the Resurrection

The defining moment for Sunday as “the first day” is Christ’s Resurrection. According to the Gospel accounts, it was “early on the first day of the week” (John 20:1) that the empty tomb was discovered. Mark underscores this timing by noting, “After Jesus had risen early on the first day of the week…” (Mark 16:9).

This event creates a profound theological foundation: if creation marked the dawning of a physical world, the Resurrection marked the dawning of a spiritual renewal. Death was defeated, and eternal hope was made possible. Because believers see this victory as a central pillar of faith, meeting on the first day became both a commemoration of Christ’s conquest of death and an affirmation of God’s transformative power in everyday life.


Early Church Observance

Historical documents outside of Scripture reinforce that Sunday worship was a fixture for the earliest Christian communities. Early writings such as the Didache (also known as “The Teaching of the Twelve Apostles”), which some place in the late first or early second century, refer to believers coming together on “the Lord’s Day” for communion and thanksgiving. Justin Martyr, writing in the second century, describes how Christians assembled on Sunday to read from the “memoirs of the apostles,” pray, and share in the Lord’s Supper.

Archaeological evidence, including inscriptions on early church gathering places, further highlights the priority the first believers gave to the Sunday meeting. These gatherings formed the bedrock of communal life and offered opportunities for teaching, mutual encouragement, and worship focused on the living Christ.


A Symbol of New Beginnings

The motif of “newness” weaves through the biblical narrative. Genesis shows God’s creative hand shaping all that is seen and unseen, beginning with light on Day One (Genesis 1:3–5). Likewise, the Resurrection on the first day of the week displays divine power bringing forth new spiritual life (John 20:1–9).

Given its status as the threshold of biblical creation and the day on which Christ rose, Sunday vividly represents a weekly reminder of God’s ongoing creative and redemptive work. Many throughout history have found this day to be a time to pause, reflect, and step back into the daily journey renewed by the truth that God’s mercies “are new every morning” (Lamentations 3:23).


Practical and Worshipful Dimensions

Beyond historical and theological underpinnings, the first day finds its significance in practical worship. Early congregations chose to gather on Sunday because it underscored the Resurrection’s centrality to the faith they proclaimed. This choice provided a consistent rhythm of praise and reflection on divine redemption (cf. Acts 2:42–47).

In modern times, Sunday worship remains a touchstone for many. Individuals and families meet in church assemblies to pray, study Scripture, and encourage one another. The spiritual focus of this first day provides a pattern that shapes the believer’s entire week, setting a tone of trust in God and a renewed commitment to walk according to His ways.


Spiritual Formation and Remembrance

When approaching the journey of faith, remembering events and their associated days becomes a building block of personal and community identity. As Israel had the Sabbath to remember God’s resting in Creation and His deliverance from Egypt (Exodus 20:8–11; Deuteronomy 5:12–15), believers in Christ observe Sunday to remember the ultimate deliverance from sin and death.

Each Sunday is a collective declaration that Jesus’ Resurrection has ushered in a new covenant and a new life (Luke 22:20). By understanding the significance of this day, believers cultivate rhythms of gratitude and share the good news of resurrection power to the world.


Encouragement for the Ongoing Journey

For the one seeking to deepen trust in God, Sunday 1 is not merely another date on the calendar. Its significance lies in the blending of history, theology, and personal formation. It is a celebration of an empty tomb, a weekly milestone of new creation, and an appointed time for communal worship.

In the ongoing journey, the first day reminds believers of the steadfast truth revealed in Scripture: that the God who called light out of darkness can and does shine light into hearts (2 Corinthians 4:6). Engaging Sunday purposefully invites a continual encounter with divine grace and hope, equipping the faithful for the days ahead and unifying them under the Resurrection’s promise.


Conclusion: A Day of Hope, Worship, and Renewal

Sunday stands as a recurring testament to the Resurrection’s reality and the continuity of God’s work in the world. It incorporates biblical history, early Christian testimony, and centuries of practice that converge around Jesus’ triumph over death on the first day of the week. This foundational element of the believer’s journey offers encouragement, shapes corporate worship, and reaffirms the believer’s trust in the power of Christ’s victory. Embracing “Sunday 1” means embracing the ever-present reminder that God’s creative and redemptive energies remain at work, sustaining and guiding the faithful through every season of life.
