Seventh Day Adventists

The Seventh Day Adventist Church on 40th Street opposite Bryant Park also is home to its Hungarian and Russian branches in New York.

To quote Wikipedia again:

The Seventh-day Adventist Church (commonly abbreviated SDA,^[2][3][4][5] officially abbreviated Adventist^[6]) is a Christian denomination which is distinguished by its observance of Saturday,^[7] the original seventh day of the Judeo-Christian week, as the Sabbath, and by its emphasis on the imminent Second Coming (Advent) of Jesus Christ. As of May 2007, it was the twelfth-largest religious body in the world,^[8] and the sixth-largest highly international religious body.^[9] The denomination grew out of the Millerite movement in the United States during the middle part of the 19th century and was formally established in 1863.^[10] Among its founders was Ellen G. White, whose extensive writings are still held in high regard by the church today.^[11]

Much of the theology of the Seventh-day Adventist Church corresponds to Protestant Christian teachings such as the Godhead and the infallibility of Scripture. Distinctive teachings include the unconscious state of the dead and the doctrine of an investigative judgment. The church is also known for its emphasis on diet and health, its holistic understanding of the person, its promotion of religious liberty, and its conservative principles and lifestyle.
