The Church of God, a Worldwide Association (COGWA) has posted the "Church of God, a Worldwide Association Fundamental Beliefs" on their website. Like most churches, the posted beliefs “do not constitute the entire body of beliefs of the Church but do represent its fundamental or foundational beliefs”, and thus should be taken as a synopsis of beliefs until weightier materials can be published.
Just as a point of reference, the writer of Hebrews, usually attributed to as Paul, also wrote about some “fundamental”, “basic” or “elementary” doctrines:
1 Therefore, leaving the discussion of the elementary principles of Christ, let us go on to perfection, not laying again the foundation of repentance from dead works and of faith toward God, 2 of the doctrine of baptisms, of laying on of hands, of resurrection of the dead, and of eternal judgment. (Hebrews 6:1-2, New King James Version)
So, just glancing through the COGWA Fundamental Beliefs, we see repentance is #9, faith is scattered throughout the document but spelled out best in #9, baptism is #10, the laying on of hands is included in #9, #4 is about resurrection (although the word is not there) and #20 specifically mentions three resurrections, including the one for eternal judgment.
Well, in spite of what some have been claiming for some time, I don’t see any specific form of government on either of those lists.
