Adventists abstain from secular work on Saturday. They will also usually refrain from purely secular forms of recreation, such as competitive sport and watching non-religious programs on television. However, nature walks, family-oriented activities, charitable work and other activities that are compassionate in nature are encouraged. Saturday afternoon activities vary widely depending on the cultural, ethnic and social background. In some churches, members and visitors will participate in a fellowship (or "potluck") lunch and AYS (Adventist Youth Service).
The conservative end of the theological spectrum is represented by historic Adventists, who are characterized by their opposition to theological trends within the denomination, beginning in the 1950s.[33] They object to theological compromises with Evangelicalism, and seek to defend traditional Adventist teachings such as the human post-fall nature of Jesus Christ, investigative judgment, and character perfectionism.[34] Historic Adventism is represented by some scholars,[35] is also seen at the grassroots level of the church[36] and is often promoted through independent ministries.
The arrival of the 20th century saw a convergence of economic factors which fueled rapid growth in Houston, including a burgeoning port and railroad industry, the decline of Galveston as Texas' primary port following a devastating 1900 hurricane, the subsequent construction of the Houston Ship Channel, and the Texas oil boom.[12] In the mid-20th century, Houston's economy diversified as it became home to the Texas Medical Center—the world's largest concentration of healthcare and research institutions—and NASA's Johnson Space Center, where the Mission Control Center is located.
Minute Maid Park (home of the Astros) and Toyota Center (home of the Rockets), are located in Downtown Houston. Houston has the NFL's first retractable-roof stadium with natural grass, NRG Stadium (home of the Texans).[207] Minute Maid Park is also a retractable-roof stadium. Toyota Center also has the largest screen for an indoor arena in the United States built to coincide with the arena's hosting of the 2013 NBA All-Star Game.[208] BBVA Compass Stadium is a soccer-specific stadium for the Houston Dynamo, the Texas Southern Tigers football team, and Houston Dash, located in East Downtown. Aveva Stadium (home of the SaberCats) is located in south Houston. In addition, NRG Astrodome was the first indoor stadium in the world, built in 1965.[209] Other sports facilities include Hofheinz Pavilion (Houston Cougars basketball), Rice Stadium (Rice Owls football), and NRG Arena. TDECU Stadium is where the University of Houston's Cougars football team plays.[210]
The Grand Prix of Houston, an annual auto race on the IndyCar Series circuit was held on a 1.7-mile temporary street circuit in NRG Park. The October 2013 event was held using a tweaked version of the 2006–2007 course.[213] The event had a 5-year race contract through 2017 with IndyCar.[214] In motorcycling, the Astrodome hosted an AMA Supercross Championship round from 1974 to 2003 and the NRG Stadium since 2003.
Adventists have long been proponents of media-based ministries. Traditional Adventist evangelistic efforts consisted of street missions and the distribution of tracts such as The Present Truth, which was published by James White as early as 1849. Until J. N. Andrews was sent to Switzerland in 1874, Adventist global efforts consisted entirely of the posting of tracts such as White's to various locations.
The Uposatha has been observed since Gautama Buddha's time (500 BCE), and is still being kept today in Theravada Buddhist countries. It occurs every seven or eight days, in accordance with the four phases of the moon. Buddha taught that Uposatha is for "the cleansing of the defiled mind", resulting in inner calm and joy. On this day, disciples and monks intensify their practice, deepen their knowledge, and express communal commitment through millennia-old acts of lay-monastic reciprocity.
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 Allen brothers—Augustus Chapman and John Kirby—explored town sites on Buffalo Bayou and Galveston Bay. According to historian David McComb, "[T]he brothers, on August 26, 1836, bought from Elizabeth E. Parrott, wife of T.F.L. Parrott and widow of John Austin, the south half of the lower league [2,214-acre (896 ha) tract] granted to her by her late husband. They paid $5,000 total, but only $1,000 of this in cash; notes made up the remainder."[18] Saturday worship service
