Not to put anyone to sleep, because explaining this shit always makes me want to take a shower...
In my JW time, it was necessary to claim Tyndale and Wycliffe as "really old dude JW's" due to Matt 13: 24-30. An enemy (SATAN!) sowed his Devil Weed Seed (FALSE CHRISTIANS!) among the poor wheat (TRUE CHRISTIANS!). In verse 30, the master (JEEBUS!) instructed his servants to 'let both the wheat and the weeds grow together until the harvest (1919! 1935! 1975! GENERATION THAT SAW 1914! UH.....) so that they would be harvested together... We JW's would be saved! (and turned into bread, because, what the hell is wheat for anyway...) while the weeds would be burnt. (pretty bad thinking, why not turn weeds into compost? I digress)
So whatever the current understanding of this "harvest" that fit the current JW narrative, the point was that there had to be "Jehovah's Witnesses" from around from the end of the 1st century all through to modern times, when CT Russell put down his bong and picked up his bible. (poetic license expressed...) Thus, Tyndale and Wycliffe were adopted by the cult leaders to fulfill a prophecy. (Yay!)
Bottom line, if there is no Tyndale and Wycliffe, then the investment that Freddie "Oops I Did It Again" Franz put into Matt 13:24-30 would have turned off a couple of generations of invested JW's. Franz conveniently waited until he was dead before the proof was soundly presented that his interpretation was in fact, laced with bullshit.
