No. Yet some of their scholars will often claim this, while at the same time admitting their flag is firmly rooted in the Radical Reformation of the Anabaptists. As SDA historian George R. Knight rightly notes in his book A Search for Identity: The Development of Seventh-day Adventist Beliefs:
North American Protestantism of the nineteenth century was a child of the sixteenth-century Reformation. Many Adventists are aware of that fact but have mistakenly concluded that their church is an heir of those branches of the Reformation initiated by Martin Luther, John Calvin, or Ulrich Zwingli. While it is true that Adventism’s concept of salvation by grace through faith came through the mainline Reformers, the theological orientation of Adventism really finds itself most at home with what church historians call the Radical Reformation or the Anabaptists.
