The CURRENT teaching among Jehovahs Witnesses is that since Pentecost of 33c.e., Jehovah has had a Faithfull and Discreet Slave class on earth AT ANY GIVEN TIME who feeds one another spiritual food. They have not deviated from this teaching.......yet nowhere will you find out WHERE Charles Taze Russell recieved a feeding from any existing Slace Class from HIS TIME.
Search all you want...and you will NEVER find a 'Slave Class' who Russell recieved his food from. All articles point to Russell as the single slave since no others were viewed as a slave of his time.....rather that TRUTHS were dispensed by him although some of his ideas originated with others....though these "others" were never recognised as a "Slave Class"..rather some men who never really had it right.

TESTS AND TEMPTATIONS
THE TEST OF LOYALTY
One of the chief temptations to the church has been in respect to loyalty to God's arrangements for it. Since the days when in the providences of God our late beloved leader came into prominnce as the chief representative of the Lord's people and stood before them as "that servant" who had charge of his Master's goods, every indication of the Lord's providence has shown that God gave Brother Russell to the church to be as a mouthpiece for him; and those who claim to have learned the truth apart from Brother Russell and his writings have been manifested by the Lord as deceivers, ready to lead the flock of God in their way.
Since Brother Russell's death the evidence of God's favor upon the Society, which was organized by Brother Russell for the furtherance of the Lord's work, has been manifested as clearly as it was previously upon him. Satan has attempted by many attacks upon this fact to break it down; to cause the Lord's people to believe: (1) that Brother Russell was not the only channel by which the Lord would lead his people; and (2) that the Society in its organized capacity could not be a channel for the Lord.
