Ethelbert William Bullinger (1837–1913) was an Anglican clergyman, Bible scholar, and ultradispensationalist theologian. He served in parish ministry throughout his life and was clerical secretary of the Trinitarian Bible Society from 1867 until his death in 1913. He is most recognizable for his role in developing ultradispensational theology, which is sometimes referred to as “Bullingerism.” His best-known works are the Companion Bible, , and .
The Companion Bible is a KJV study Bible with extensive notes written by E.W. Bullinger from 1908 until his death in 1913. It has notes on Hebrew and Greek, 198 Appendixes, and lots more. The online Companion Bible can be searched or printed. I find it to be a fascinating study Bible. You can read here:
This enlarged print edition of the Companion Bible with commentary by E W Bullinger is an excellent choice for the serious student of God's word. It's also a good Bible to just read, since the text is clear and dark. Just be prepared to get comfortable with a large book if you choose this one.
