Well known but distant offshoots are the Davidian Seventh-day Adventist organization and the Branch Davidians, themselves a schism within the larger Davidian movement.[135] The Davidians formed in 1929, following Victor Houteff after he came out with his book The Shepherd's Rod which was rejected as heretical. A succession dispute after Houteff's death in 1955 led to the formation of two groups, the original Davidians and the Branches. Later, another ex-Adventist, David Koresh, led the Branch Davidians until he died in the 1993 siege at the group's headquarters near Waco, Texas.
"As the Sabbath day appears to have been quite as commonly observed at this date as the sun's day (if not even more so), it is just as probable that this `stated day' referred to by Pliny was the 7th day as that it was the 1st day; though the latter is generally taken for granted." "Sunday was distinguished as a day of joy by the circumstances that men did not fast upon it, and that they prayed standing up and not kneeling, as Christ had now been raised from the dead. The festival of Sunday, like all other festivals, was always only a human ordinance, and it was far from the intentions of the apostles to establish a divine command in this respect, far from them, and from the early apostolic church, to transfer the laws of the Sabbath to Sunday. Perhaps at the end of the 2nd century, a false application of this kind had begun to take place; for men appear by that time to have considered laboring on Sunday as a sin" (Tertullian De Orat., c. 23). This quotation is taken from Rose's Neander, London, 1831, I, 33, and is the correct translation from Neander's first German edition, Hamburg, 1826, I, pt. 2, p. 339. Neander has in his 2nd edition, 1842, omitted the second sentence, in which he expressly stated that Sunday was only a human ordinance, but he has added nothing to the contrary. "The Christians in the ancient church very soon distinguished the first day of the week, Sunday; however, not as a Sabbath, but as an assembly day of the church, to study the Word of God together and to celebrate the ordinances one with another: without a shadow of doubt this took place as early as the first part of the 2nd century" (Geschichte des Sonntags, 60).
The consistency of the prophets' call to honor the Sabbath testifies in part to the growing need, especially during the exilic period, to preserve Jewish identity in a pagan environment. In this sense prophetic aims are continuous with those of the Mosaic period. But scholarly consensus finds in the prophetic writings a subtle transformation wherein the Sabbath, formerly a social institution of festivity, rest, and worship, became above all a religious mark of personal and national holiness vis-a-vis the Gentiles.
The great majority of slaves in Texas came with their owners from the older slave states. Sizable numbers, however, came through the domestic slave trade. New Orleans was the center of this trade in the Deep South, but slave dealers were in Houston. Thousands of enslaved blacks lived near the city before the American Civil War. Many of them near the city worked on sugar and cotton plantations, while most of those in the city limits had domestic and artisan jobs.
Houston has excessive ozone levels and is routinely ranked among the most ozone-polluted cities in the United States.[87] Ground-level ozone, or smog, is Houston's predominant air pollution problem, with the American Lung Association rating the metropolitan area's ozone level twelfth on the "Most Polluted Cities by Ozone" in 2017, after major cities such as Los Angeles, Phoenix, New York City and Denver.[88] The industries located along the ship channel are a major cause of the city's air pollution.[89] The rankings are in terms of peak-based standards, focusing strictly on the worst days of the year; the average ozone levels in Houston are lower than what is seen in most other areas of the country, as dominant winds ensure clean, marine air from the Gulf.[90]
Adventists run a large number of hospitals and health-related institutions. Their largest medical school and hospital in North America is Loma Linda University and its attached Medical Center. Throughout the world, the church runs a wide network of hospitals, clinics, lifestyle centers, and sanitariums. These play a role in the church's health message and worldwide missions outreach.[90]
The first task of the scientists was to find people who were willing to be infected by pathogens that could make them very sick. They found them in the followers of the Seventh-day Adventist faith. Although willing to serve their country when drafted, the Adventists refused to bear arms. As a result many of them became medics. Now the U.S. was offering recruits an opportunity to help in a different manner: to volunteer for biological tests as a way of satisfying their military obligations. When contacted in late 1954, the Adventist hierarchy readily agreed to this plan. For Camp Detrick scientists, church members were a model test population, since most of them were in excellent health and they neither drank, smoked, nor used caffeine. From the perspective of the volunteers, the tests gave them a way to fulfill their patriotic duty while remaining true to their beliefs.[54]
What does the Bible really say about the Sabbath? It is generally assumed that Sunday is the correct day. Is it possible that all of these churches are wrong on this fundamental doctrine? And, after all, does it make any difference? Do we not have to adjust our religion to the changing times? Was not the law—including the Sabbath—"nailed to the cross" when Christ died? What about scriptures like Galatians 4:10 or Colossians 2:16—do they not prove that it does not matter which day we keep? Was not Christ resurrected on Sunday, thus His day is the "Lord's Day?"

Douty, Herbert S. Bird, E. B. Jones, Louis B. Talbot and M. R. DeHaan. See "Questions on Doctrine, annotated edition". Andrews University Press. 2003: xiii–xxxiii Sabbath-keeping
