In the last century, these efforts have also made use of emerging media such as radio and television. The first of these was H. M. S. Richards' radio show Voice of Prophecy, which was initially broadcast in Los Angeles in 1929. Since then, Adventists have been on the forefront of media evangelism; It Is Written, founded by George Vandeman, was the first religious program to air on color television and the first major Christian ministry to utilize satellite uplink technology. Today the Hope Channel, the official television network of the church, operates 8 international channels broadcasting 24 hours a day on cable, satellite, and the Web.[95]
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]
We tend to think of sabbatical in academic terms, as a school year free from teaching duties that can be devoted to research, travel, and writing. Traditionally, this occurs every seventh year. Because of this scholarly context, we may easily miss what is hiding in plain sight: that sabbatical is related to Sabbath, which refers to the Biblical day of rest, or the seventh day. We trace the origins of both sabbatical and Sabbath to the Greek word sabbaton. Sabbaton itself traces to the Hebrew word shabbāth, meaning “rest.”
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 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]
The Adventist church has released official statements in relation to other ethical issues such as euthanasia (against active euthanasia but permissive of passive withdrawal of medical support to allow death to occur),[63] birth control (in favor of it for married couples if used correctly, but against abortion as birth control and premarital sex in any case)[64] and human cloning (against it while the technology is unsafe and would result in defective births or abortions).[65]
