Even as Bible prophecy pointed forward to the Messiah, it also directs us to the close-knit body of anointed Christian Witnesses that now serve as the faithful and discreet slave. It helps us to understand the Word of God. All who want to understand the Bible should appreciate that the “greatly diversified wisdom of God” can become known only through Jehovah’s channel of communication, the faithful and discreet slave.—John 6:68. ( The Watchtower, 01. October 1994, P.8)
Two problems:
1) C. T. Russell is portrayed in Watchtower histories as having studied independently, evidently finding it unnecessary to identify and join himself to the supposed "faithful and discreet slave" of his day.
2) Note the typical egregious (mis)use of the cited scripture. They are effectively equating themselves with Jesus Christ.
