The term "Governing Body" is not in the Bible. They tend to squirm out of such reasoning with something like this, "the word 'Bible' is not in the Holy Scriptures but you still say it, right?" "The Holy Scriptures" (2 Tim. 3:15) is a reference to the 'Bible'. What information is in the "Holy Scriptures" that give us an explanation of the term 'Governing Body'?
"Holy Scriptures" is to "Bible" like "Governing Body" is to ??? The Apostles perhaps??
I do not see the correlation
