The theology of the Seventh-day Adventist Church largely resembles that of mainstream Protestant Christianity, and in particular evangelicalism. Most significantly, Adventists believe in the authority of Scripture and teach that salvation comes through faith in Jesus Christ. The 28 fundamental beliefs constitute the church's official doctrinal position.The denomination also has a number of distinctive teachings which differentiate it from other Christian churches (although some of these beliefs are also held in other churches). Most notably, Adventists believe in the perpetuity of the Ten Commandments, the unconsciousness of man in death, conditional immortality, an atoning ministry of Jesus Christ in the heavenly sanctuary, and an investigative judgment that commenced in 1844.
