Adventism
United Church of God
In the 1930s, the Worldwide Church of God rejected a set of distinctive doctrines and practices that had been advocated by its founder Herbert W. Armstrong. As a result, a large percentage of its ministers and members left the church and formed a number of splinter groups (as many as 150 have been counted), though most are very small house churches with but a single small center of activity. The great majority of members adhered to one of the three relatively large groups—the Living Church of God, the United Church of God, and the Philadelphia Church of God—which vary among themselves on the number of former distinctives they have maintained.
