Counting from the new moon, the Babylonians celebrated the 7th, 14th, 21st, and 28th as "holy-days", also called "evil days" (meaning "unsuitable" for prohibited activities). On these days officials were prohibited from various activities and common men were forbidden to "make a wish", and at least the 28th was known as a "rest-day". On each of them, offerings were made to a different god and goddess. Tablets from the 6th-century BCE reigns of Cyrus the Great and Cambyses indicate these dates were sometimes approximate. The lunation of 29 or 30 days basically contained three seven-day weeks, and a final week of nine or ten days inclusive, breaking the continuous seven-day cycle. The Babylonians additionally celebrated the 19th as a special "evil day", the "day of anger", because it was roughly the 49th day of the (preceding) month, completing a "week of weeks", also with sacrifices and prohibitions. Difficulties with Friedrich Delitzsch's origin theory connecting Hebrew Shabbat with the Babylonian lunar cycle include reconciling the differences between an unbroken week and a lunar week, and explaining the absence of texts naming the lunar week as Shabbat in any language. Reconstruction of a broken tablet seems to define the rarely attested Babylonian Akkadian word Sapattum or Sabattum as the full moon: this word is cognate or merged with Hebrew Shabbat, but is monthly rather than weekly. It is regarded as a form of Sumerian sa-bat ("mid-rest"), attested in Akkadian as um nuh libbi ("day of mid-repose"). This conclusion is a contextual restoration of the damaged Enûma Eliš creation mythos, which is read as: "[Sa]pattu shalt thou then encounter, mid[month]ly."
Apart from His claim to be the Messiah, there is no subject on which our Lord came into such sharp conflict with the religious leaders of the Jews as in the matter of Sabbath observance. He set Himself squarely against the current rabbinic restrictions as contrary to the spirit of the original law of the Sabbath. The rabbis seemed to think that the Sabbath was an end in itself, an institution to which the pious Israelite must subject all his personal interests; in other words, that man was made for the Sabbath:
Sabbath (as the verb שָׁבַת֙ šāḇaṯ) is first mentioned in the Genesis creation narrative, where the seventh day is set aside as a day of rest (in Hebrew, shabbath), and made holy by God (Genesis 2:2–3). Observation and remembrance of Sabbath (Hebrew: שַׁבָּת šabbaṯ) is one of the Ten Commandments (the fourth in the original Jewish, the Eastern Orthodox, and most Protestant traditions, the third in Roman Catholic and Lutheran traditions). Most Jews who observe the Sabbath regard it as having been instituted as a perpetual covenant for the Israelites (Exodus 31:13–17), as a sign respecting two events: the day during which God rested after having completed Creation in six days (Exodus 20:8–11), and the Israelites' deliverance from Egypt (Deuteronomy 5:12–15). However, most Sabbath-keeping Christians regard the Sabbath as having been instituted by God at the end of Creation week, and that the entire world was then, and continues to be, obliged to observe the seventh day as Sabbath. Originally, Sabbath-breakers were officially to be cut off from the assembly or potentially killed (Exodus 31:15). Observance in the Hebrew Bible was universally from sixth-day sundown to seventh-day sundown (Nehemiah 13:19, cf. Leviticus 23:32),[2] on a seven-day week. Consultations with prophets (II Kings iv. 23) were sought on the Sabbath.[3] Sabbath corporate worship was not prescribed for the community at large and the Sabbath activities at the shrines were originally a convocation of priests for the purpose of offering divine sacrifices with family worship and rest being centered in homes.[4][5]
After a brief break, the community joins together again for a church service that follows a typical evangelical format, with a sermon as a central feature. Corporate singing, Scripture readings, prayers and an offering, including tithing (or money collection), are other standard features. The instruments and forms of worship music vary greatly throughout the worldwide church.[42] Some churches in North America have a contemporary Christian music style, whereas other churches enjoy more traditional hymns including those found in the Adventist Hymnal. Worship is known to be generally restrained.
Much of the theology of the Seventh-day Adventist Church corresponds to common Protestant Christian teachings, such as the Trinity and the infallibility of Scripture. Distinctive teachings include the unconscious state of the dead and the doctrine of an investigative judgment. The church is known for its emphasis on diet and health, its "holistic" understanding of the person,[7] its promotion of religious liberty, and its conservative principles and lifestyle.[8]
The church's beliefs and doctrines were first published in 1872 in Battle Creek Michigan as a brief statement called "A Synopsis of our Faith".[16] The church experienced challenges as it formed its core beliefs and doctrines especially as a number of the early Adventist leaders came from churches that held to some form of Arianism (Ellen G. White was not one of them).[17] This, along with some of the movement's other theological views, led to a consensus among conservative evangelical Protestants to regard it as a cult.[18][19][20][21] According to Adventist scholars,[22] the teachings and writings of White, ultimately proved influential in shifting the church from largely semi-Arian[23] roots towards Trinitarianism.[24] Adventists, for the most part, credit her with bringing the Seventh-day Adventist church into a more comprehensive awareness of the GodHead during the 1890s. The Adventist Church adopted Trinitarian theology early in the 20th century and began to dialogue with other Protestant groups toward the middle of the century, eventually gaining wide recognition as a Protestant church. Christianity Today recognized the Seventh-day Adventist church as " the fifth-largest Christian communion worldwide" in its January 22, 2015 issue.[25]
Accordingly, many Adventists are opposed to practices such as body piercing and tattoos and refrain from the wearing of jewelry, including such items as earrings and bracelets. Some also oppose the displaying of wedding bands, although banning wedding bands is not the position of the General Conference.[66] Conservative Adventists avoid certain recreational activities which are considered to be a negative spiritual influence, including dancing, rock music and secular theatre.[67][68] However, major studies conducted from 1989 onwards found that a majority of North American church youth reject some of these standards.[69]
Because of this diet, many experts have said Seventh Day Adventists can live an average of 10 years longer than most Americans. In a study from Loma Linda University, scientists found that Adventists can die of cancer, stroke or heart disease, but the age at which those diseases and illnesses are diagnosed is much later because of their healthy lifestyle and resting on the Sabbath.
