Despite his own unique teaching on baptism his own account is noteworthy for the absence of any mention of the process of laying on of hands or a special prayer in the dispensation of the Holy Spirit, which were considered fundamental for membership in the Worldwide Church of God and reason for many a new convert's rebaptism. In 1931 Armstrong became an ordained minister of the Oregon Conference of the Church of God (Seventh Day). The existence and history of this church became a significant factor in Armstrong's later beliefs. "Baptism and Ordination of Herbert W Armstrong"  While a member of The Church of God (Seventh Day), Armstrong became acquainted with ministers John Kiesz and Israel Hager who began to suspect that Herbert was a little too arrogant and tended to go against church doctrine. They cited Armstrong's refusal to submit to the Church of God ministers to be baptized but went out to a local Baptist minister instead as a point. After his ordination, Armstrong allied himself with two other rogue ministers by the names of Andrew Dugger and C. O. Dodd, both of which had composed a book called "A History of the True Religion, from 33 AD to Date", in which they claimed that the New Testament Church of the first century had secretly descended through history and eventually became the Sabbath-keeping Church of God (Seventh Day). Dugger also predicted that the apocalypse would occur in 1936. Eventually, this led to Dugger and Dodd's ouster and when they promised to make Armstrong an apostle in their new church, The Church of God (Seventh Day), he joined with them. After severing ties with the Church of God (Seventh Day) as the result of doctrinal disputes, he began to teach a form of British Israelism, which would later make up his book "The United States and Britain in Prophecy". His ministerial credentials with Dugger's church were revoked in 1938. This, Armstrong believed, indicated God was now directing him in leading a revived work into the next "church era." In October 1933, a small 100-watt radio station in Eugene, Oregon, KORE, offered free time to Armstrong for a morning devotional, a 15-minute time slot shared by other local ministers. After positive responses from listeners, the station owner let Armstrong start a new program of his own. On the first Sunday in 1934, the Radio Church of God first aired. These broadcasts eventually became known as "The World Tomorrow" of the future Worldwide Church of God. Shortly thereafter, in February 1934, Armstrong began the publication of "The Plain Truth", which started out as a church bulletin.
