Adventism holds to beliefs that weren’t taught by early Christians. These innovations came from human reasoning during the so-called Reformation and later periods. Was the entire Christian Church wrong for 1500 years? Some groups claim spiritual ties with certain sects that existed in the past, to try to trace their roots to the Apostles without acknowledging Catholicism as the original Christian Church. But were these sects even Christian? And what were the beliefs of the early Christians, and do they reflect Catholic or Protestant (or Adventist, etc.) beliefs?
