Modern Seventh Day Adventism traces its origins back to the early 1800's to Mr. William Miller (1782-1849) of Low Hampton, New York. Mr. Miller had converted from deism to Christianity in 1816 and became a Baptist. He was an avid reader, dedicated to God's word, and sought to reconcile apparent biblical difficulties raised by deists. He relied heavily on the Cruden's Concordance in his studies and developed a focus on the imminent return of Jesus. He began preaching at the age of 50.
The time was right. America was hot with discussions on the return of Christ. As a result, many thousands (called Millerites) accepted his idea that Jesus would return in the year covering 1843-1844. He had arrived at this date based upon a study of Daniel 8:14 which says, "And he said to me, "For 2,300 evenings and mornings; then the holy place will be properly restored." He interpreted the 2300 evenings and mornings to be years and counted forward from 457 BC when the commandment to rebuild Jerusalem was given (Dan. 9:24-25).1 When his initial predictions failed, he adjusted his findings to conclude that Jesus would return on March 21, 1844 and then later on October 22, 1844. After these too failed, Miller quit promoting his ideas on Jesus' return and the "Millerites" broke up.
