Spectrum has posted an article related to a SDA pastor who has departed SDA ministry over doctrinal issues that have included Sunday worship. You may read that article at:

In responding to that article, I have posted the following:
Contrary to what many SDAs believe, our doctrinal position does not prohibit worship services on Sunday. In the quote below, Ellen White clearly approves of such. SDA clergy serving as Federal (US) chaplains typically conduct worship services on Sundays. As a SDA pastor in the Potomac Conference, I sometimes spoke on Sundays in other churches. In addition, we had a pastor who preached on Sunday in a congregation that was searching for a new pastor. The SDA position is in support of the Sabbath on what is generally called Saturday in the English-speaking world. In addition, the Sabbath, as SDAs understand it, is much more than three hours of worship services. It is 24-hours of spiritual refreshment and communion with God. In short, SDA clergy are expected to support the Sabbath. They are not required to never worship on Sunday. While I did conduct worship services on Sundays, in the past, I was always in a SDA congregation on a Sabbath which I considered to consist of 24-hours. In addition, I used the Sunday services that I conducted to inform the congregation as to why SDAs advocte for the Biblical Sabbath. After one such service, one of the members said to me: “Well chaplain, you have certainly given us something to think about today.”
