I'm afraid you're still misunderstanding. In any sense of the word the President of UCG is not the "head" of the church either in a corporate or spiritual sense. The president is an administrative position that administers the physical operation of the organization. The council of elders, the 12 persons elected by the general conference of elders, are the governing body of the organization with the ultimate responsibility for the overall operation of the church. But even they answer to Jesus Christ.
I sense that you're not really interested in discussion because every time I post something that I feel is a direct and clear answer you come back kind of hostile (in my estimation) and contradictory. So I'm going to end this line of discussion.
I don't mean to not address certain doctrinal points but that really isn't the purpose of the thread. If you look at some of the past stuff that I've posted you can get a pretty good idea of what Christ taught according to scripture.
Take care and God bless...
The purpose of the thread, looking at the original post, was to promote the UCG doctrines concerning ecclesiology.
If the purpose of the thread was not to initiate a discussion of UCG doctrine, then the thread had no purpose to begin with.
