The Watchtower Publication, Should You Believe In the Trinity? attacks the doctrine of the Trinity. Gross misquotations and taking sources out of context are standard fare as the Watchtower attempts to prove that the early Christian Fathers and Christian scholars did not teach that Jesus is God. In response to the book, this training set documents, explains and refutes the Watchtower errors.

This training set is also available in the Deluxe Jehovah's Witnesses Library.
