In the "Proclaimers" chapter 10 it reads about Russell:
"As a youth, Russell had joined the Congregational Church and was active in its work, but the unreasonableness of traditional dogmas led to his becoming a skeptic. He found that what he had been taught could not be defended from the Bible in a satisfying way. So he discarded the dogmas of church creed and, with them, the Bible. Next, he explored leading Oriental religions, but they too proved unsatisfying. Then he began to wonder if perhaps the Bible was being misrepresented by Christendom’s creeds. Encouraged by what he heard one evening at an Adventist meeting, he began a systematic study of the Scriptures. What he saw unfolding before him was indeed the inspired Word of God."
What are oriental religions here really about? Was it in fact Freemasonry he studied?
