The apostle John, who received the Revelation, attests: “I heard the number of those who were sealed, a hundred and forty-four thousand.” (Revelation 7:4) This precise number is confirmed in a later chapter as being the total of those “bought from among mankind” to rule with the Lamb on the heavenly Mount Zion. (Revelation 14:1-4)
While the churches of Christendom give vague and unconvincing explanations of this number, interestingly, Bible scholar E. W. Bullinger says of it: “It is the simple statement of fact: a definite number in contrast with the indefinite number in this very chapter.”

The above quote is taken from the above mentioned watchtower but raises more questions than it answers. EW Bullinger was also an Anglican Clergyman, so wasn't he considered as being from the churches of Christendom by the JWs? Why are the JWs using his comments because it supports their idea? Why do they need to source opinions from other scholars?
