Dr. Herman Hoeh, an evangelist in the Worldwide Church of God during the early 1960s, believed that Pentecost should be observed on Sunday rather than Monday, as was the practice at the time. Despite his belief, when a paper advocating for Sunday observance was rejected by the church leadership, Hoeh chose not to cause division. Instead of starting his own church or publicly pushing for the change, he kept Pentecost on both Sunday and Monday to maintain unity within the church. His patience was rewarded when the church officially changed to Sunday observance in 1974, over a decade later. Hoeh's actions demonstrated his understanding of his role within the church's hierarchy and his commitment to waiting for God's timing rather than acting impulsively.

Dr. Herman Hoeh played a significant role in tracing the historical and doctrinal roots of the Radio Church of God and later the Worldwide Church of God. In his booklet, *A True History of the True Church*, first published in 1959, he explored the origins of the church by identifying doctrinal correspondences with religious groups documented in histories dating back 2,000 years. Hoeh determined that groups such as the Nazarenes, Bogomils, Paulicians, Waldensians, Lollards, and Sabbatarian Baptists, among others, were spiritual ancestors of the present-day church of God, often relying on information from their enemies. He also identified key leaders like Polycarp, Polycrates, Peter Waldo, and Walter Lollard, associating them with specific periods. By aligning these groups and leaders with the churches listed in Revelation 2 and 3, Hoeh constructed a chain of church eras linked through centuries by common doctrines.
