Didn't you know?
This worldwide evangelizing organization is not tailored according to any present-day legal corporation that may be required under the laws of man-made political governments that now face destruction in the “war of the great day of God the Almighty” at Har–Magedon. (Rev. 16:14-16) No legal corporation of earth shapes the evangelizing organization or governs it. Rather, it governs such corporations as mere temporary instruments useful in the work of the great Theocrat. Hence it is patterned according to His design for it. It is a theocratic organization, ruled from the divine Top down, and not from the rank and file up. The dedicated, baptized members of it are under Theocracy! Earthly legal corporations will cease when the man-made governments that chartered them perish shortly. But the theocratic organization will live on, serving its Supreme Theocratic Ruler. Under his protection it will enter into his righteous new order. It will be right there on hand, as soon as the “great tribulation” is over, and be instantly ready to serve as His instrument in his new order.
The Watchtower 1971, December 15, page 754 par. 29
FYI: After all competition is eliminated, the WTBTS will direct affairs from the top down just like any present-day legal corporation.
