Funny.
The Watchtower has never had a Theocratic Ministry School.
Russell and the Watchtower are followers of Arius. Excommunicated from the Catholic Church in 320 AD. Ordered that he be excommunicated, banished, and all his works to be burned. The New Testament is very specifically a collection of books that refute his teachings. The Bible is in fact exactly opposite of everything Arius and the Watchtower ever taught. The Bible is the opposite of the Watchtower - by plan an design.
How would they have a school of Theology? The Bible forbid them and all false prophets. They are not even allowed to use the Bible - they were excommunicated in 320 AD.
