On Sunday, April 12, 2026, Pope Leo XIV addressed the faithful gathered in St. Peter’s Square, declaring Sunday to be the indispensable day of worship for Christians. In doing so, he reaffirmed one of the core pillars of Catholic theology: that Sunday stands as the focal point of spiritual life for all believers.
The Holy See Press Office published the following statement made by Pope Leo:
• “Dear brothers and sisters, happy Sunday and happy Easter once again!” [1]
• “The Sunday Eucharist is indispensable to the Christian life. Tomorrow I will depart for my apostolic journey to Africa. Some of the martyrs of the early African Church, particularly the Martyrs of Abitene, have left us a beautiful testimony in this regard. When offered the chance to save their lives by renouncing the celebration of the Eucharist, they replied that they could not live without celebrating the Lord’s Day. It is there that our faith grows and is strengthened. It is there that our efforts, though limited, are united by God’s grace to the actions of the members of a single body — the Body of Christ — for the accomplishment of a single great plan of salvation that embraces all humanity.” [1]
• “It is through the Eucharist that our hands become the hands of the Risen One, giving witness to his presence, mercy and peace. The signs of work, sacrifice, illness and the passing of the years are often etched into our hands, just as they are in the tenderness of a caress, a handshake, or a gesture of charity.” [1]
When the Pope speaks of the “Sunday Eucharist” as indispensable, he is directly linking the Christian life to participation in the Sunday Eucharistic mass. By claiming that early Christian martyrs could not live without celebrating the Lord’s Day and that they chose death rather than renounce Sunday worship, the Pope is using this argument to reinforce the false notion that, in some way, the Christian faith is inseparable from Sunday observance.
The Pope’s claim places human tradition above the Word of God. The Scriptures—and not the teachings of the Church—define true worship; likewise, the Bible consistently identifies the seventh day—and not Sunday—as the Lord’s holy day (Exodus 20:8–11; Mark 2:27–28). The Martyrs of Abitene, cited by Pope Leo, may have died sincerely embracing the tradition of Sunday; however, sincerity does not establish truth. Faithfulness is defined by obedience to the Word of God and not by embracing traditions that emerged 300 years after the apostolic era.
In the year 365 A.D., the Catholic Church, through the Council of Laodicea, declared what is commonly cited as Canon 29, which directly addressed the observance of the Sabbath. This canon instructed that Christians were not to “Judaize” by resting on the seventh day—the Sabbath—but rather, on the contrary, were to work on that day and honor Sunday as the Lord’s Day. This decree formally declared the observance of the seventh day as anathema (cursed) and elevated Sunday as the preferred day of worship.
Shortly thereafter, throughout Christian history, the Roman Catholic Church persecuted groups of Christians who observed the seventh-day Sabbath—Saturday—as a biblical commandment, viewing their refusal to fully embrace Sunday as the primary day of rest and worship as defiance of Rome’s authority. Those who chose to remain loyal to Scripture rather than ecclesiastical tradition were often marginalized, branded as heretics, and subjected to various forms of punishment.
Such persecution is the result whenever the church unites with the state to advance its teachings. Such a union leads to the suppression and eventual persecution of all dissenting voices. History shows that Rome has repeatedly suppressed biblical teachings while promoting a different day of rest—Sunday—elevating human tradition above the clear command of Scripture. When religious authority is backed by civil power, matters of faith become subject to coercion, placing those who remain faithful to biblical truth out of favor with the prevailing popular beliefs.
