Here is something I came across, "Europe grappled with Martin Luther's appeal for a return to "the Bible, and the Bible only," the hearts of many of them were deeply stirred. The cry, sola scriptura, soon rang from their lips also, and they too determined to put aside tradition in favor of the Word of God.... Andreas Fischer and Oswald Glait,8 who asked whether Christians had any basis in sola scriptura for observing the first day of the week instead of the seventh, both ultimately died for their faith.
Fortunately for us, Luther sent theologians to dialog with Fischer and Glait. From their records we learn that Fischer and Glait insisted that Jesus nowhere asked His followers to keep holy the day on which He rose from the dead. They asked where any scriptural authority could be found for such a belief. Certainly the second- and third-century church fathers had never cited such a command from Christ, and Fischer and Glait affirmed that they couldn't find one either.
The Sabbath, said these Sabbatarians, was not to be confused with the types and symbols of the ceremonial law. It was not to be linked with circumcision and sacrifice. The Sabbath, they said, was sanctified by God as far back as Creation week; thus the Sabbath was made for man (Mark 2:27) before man sinned, before he needed a ceremonial system.
Further, Glait and Fischer emphasized that the seventh-day Sabbath was placed in the Ten Commandments, where it stands not as a typological ceremony prefiguring the future coming of Christ as Redeemer but as an appropriate memorial to work previously completed by Christ as Creator. According to the Bible, said these men, the Sabbath belongs to the unchangeable moral law.
And if Jesus nowhere asked His followers to change from the seventh to the first day, did He anywhere state the opposite, that they should not? In the Sermon on the Mount, Glait and Fischer observed, Jesus said, "Think not that I have come to abolish the law and the prophets; I have not come to abolish them but to fulfill them. For truly, I say to you, till heaven and earth pass away, not an iota, not a dot, will pass from the law until all is accomplished" (Matt. 5:17, R.S.V.). But did His apostles change the day? Glait and Fischer pointed to the second chapter of the book of James, where an apostle says that if we break the law in any one point we break it all."....Sabbath and Sunday Observance in the Early Church-https://www.ministrymagazine.org/archive/1977/01/sabbath-and-sunday-observance-in-the-early-church-p.-1
