The most liberal elements in the church are typically known as progressive Adventists (progressive Adventists generally do not identify with liberal Christianity). They tend to disagree with the traditional views concerning the inspiration of Ellen White, the Sabbath, a seven-day Creation, the doctrine of the remnant and the investigative judgment.[34][37] The progressive movement is supported by some scholars[38] and finds expression in bodies such as the Association of Adventist Forums and in journals such as Spectrum and Adventist Today.
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]
That the Sabbath was known to those who came out of Egypt, even before the giving of the Law at Sinai, is shown from the experience with the manna, as recorded in Exodus 16:22-30. The double portion on the sixth day, and its preservation, was the constantly recurring miracle which reminded the people of their obligation to observe the Sabbath, and that the Sabbath was a definite day, the seventh day. To the people, first wondering at this remarkable occurrence, Moses said, "This is that which the Lord hath said, To morrow is the rest of the holy sabbath unto the Lord" (Exodus 16:23, King James Version). And to some who went out to gather manna on the seventh day, the Lord administered this rebuke:
In 1900, after Galveston was struck by a devastating hurricane, efforts to make Houston into a viable deep-water port were accelerated.[23] The following year, the discovery of oil at the Spindletop oil field near Beaumont prompted the development of the Texas petroleum industry.[24] In 1902, President Theodore Roosevelt approved a $1 million improvement project for the Houston Ship Channel. By 1910, the city's population had reached 78,800, almost doubling from a decade before. African Americans formed a large part of the city's population, numbering 23,929 people, which was nearly one-third of Houston's residents.[25]
In relating to the seventh and other days of the month, the Zoroastrian calendar contributed to the Jewish calendar.[19] A number of writings by early Christians in the New Testament apocrypha (Zostrianos, Marsenes and Allogenes) describe God's revelation received by a man named Zostrianos. Further evidence of Zoroastrian influence on Judaic tradition is demonstrated through Nehemiah, the Priest in the Book of Nehemiah, a book of the Neviim contained in the Tanakh. With the support and protection of Artaxerxes I of Persia (445/444 BCE), Nehemiah purified the Temple and the priests and Levites and enforced the observance of the law of Moses.[20] Sabbath follower
