I hear that because enough men are not reaching out to be MS, that the WTS is training baptized single women in good standing that have been baptized for 10 years, average 20 hours a month, miss no more than 1 meeting a year, and comment once at every meeting. It is a return to the procedures in the 1950's.
*** w51 9/1 p. 543 Questions From Readers ***We view a head-covering necessary under two conditions: (1) when a sister receives an appointment through the congregation or theocratic organization to keep order and conduct congregational meetings, and (2) when she is married and must show submission to the one God has made head of the family, the husband. These two principles enable one to decide for herself the requirement of varying situations.
*** w57 2/15 p. 123 par. 6 Overseers of the Ministry ***But what if there are not sufficient dedicated men in a congregation? Can women be appointed to services? Yes, qualified sisters are appointed in such cases and care for the duties outlined. If there are no male appointed overseers, sisters have the responsibility to preside over meetings. In recognition of the theocratic headship of man and realizing that she is temporarily or circumstantially serving in the congregation in place of a man who should fill that position, it is proper for the sister while so serving to wear a head covering. When a brother moves into the area or local men learn the truth, qualify and are appointed overseers, it is a time of happiness for such sisters. Gladly they give way to the brother in recognition of Jehovah’s theocratic arrangement.—Eph. 5:24-32, NW. (See “This Means Everlasting Life”, pages 154-163, for additional information on “Woman’s Privileges in the Congregation.”)
JUST KIDDING (but the references are true, I was in a congregation where there were no "qualified" brothers and a sister did the WT study, book study, and all the administrative paperwork)
