What are we not to understand?

PT. 1979 Pg. 50:

...we are not to understand that during the Gospel Age, or Church Age, God called two classes to salvation; for the Scripture states, "Ye are called in one hope of your calling" (Eph. 4: 4); that is, we are not to understand that God offered two sets of people two different salvations during the Gospel Age, as inducements for them to love and serve Him; for such a thing is nowhere taught in the Bible. Rather, there has been only one salvation offered to those who during the Gospel Age would turn from sin to righteousness, from Satan to God and Christ. To all of these God offered as the prize (Phil. 3: 14) the Divine nature (2 Pet. 1: 4) and eternal life in joint-heirship with Christ as His Bride, His Body members (Rom. 8: 17; 12: 4, 5; 1 Cor. 12: 12-27; 2 Cor. 11: 2, 3; Eph. 4: 4-14; 5: 22-33; Rev. 21: 9, 10), on condition of faithfulness unto death in following Christ (Rev. 2: 10).

As Respects the Youthful Worthies

PT. 1972, Pg. 79, Questions (52): As respects the Youthful Worthies, what came forth from the Scriptures from time to time after the fall or 1914?

Par. 52, Pg. 76, Col. 2: "As time went on after the fall of 1914, more and more evidences from the Scriptures were brought forth to prove that there was a class, viz., the Youthful Worthies, consecrating after the High Calling closed, that did not have their consecration pictured at the First Veil, nor their standing as fully consecrated believers pictured in the Holy (where all fully consecrated believers who were under the High Calling had their standing pictured), but rather in the Court."

Bro. Johnson reaffirmed and defended this teaching...

YOUTHFUL WORTHIES ALSO HAVE PRECEDENCE - PT 1973 Pg. 26

"(5) Bro. Russell further showed that from 1881 onward there were consecrated ones for whom no crowns were available, who would be counted in with the Ancient Worthies in nature and reward (F 156, 157; Z 4836, pars. 3-6, 10, 11; 5761, col. 2, pars. 1, 2; Question Book, pp. 151, 152, 154, 156-158). Bro. Johnson reaffirmed and defended this teaching also, and gave many Scriptures to prove it. He referred to this Spirit-enlightened but not Spirit-begotten class as the Youthful Worthies"

Each Class to Keep within the Bounds Set for It

PT July-August 1966, p. 54:
"Bro. Johnson expounds in E 11, p. 336, stating in part that Jesus 'severed the classes from one another by peculiar teachings, activities, gatherings and siftings, belonging to each one: the Little Flock distinct from the Great Company, the Great Company from the Youthful Worthies [italics ours], the Youthful Worthies from the justified, the justified from the Campers, and the Campers from those beyond the Camp (set bounds unto the people, v. 12). The charge was to each class to keep within the bounds set for it (take heed to yourselves), and thus not grasp for powers as to the Kingdom not belonging to it (go not up into the mount), nor contaminate anything pertaining to the Kingdom either by false doctrine or wrong practice (touch the border of it)..."

Jesus severed the Little Flock from the Great Company, the Great Company from the Youthful Worthies, etc., showing the proper order of the development of each class. See also PT August 1942, p. 120; E11, Chapter 5; PT July-August 1960, p.58; PT March-April 1976, p. 30.
