This can be confusing because the WTS has adjusted from not having a clergy class to not having a "paid" clergy class.
"A congregation of brothers precludes having a proud clergy class that honors itself with high-sounding titles and elevates itself above a laity" WT 6/1/2001 p. 12, pp 11. still same idea in 2021 WT October, p. 20, pp. 7, but 2022 in the WT publication, Frequently Asked Questions About Jehovah’s Witnesses, page 13, the WTS inserts "paid" in front of "clergy perhaps to shore up their current statement in secular courts they have clergy, just not paid) "Following the model of first-century Christianity, Jehovah’s Witnesses have no clergy-laity division. All baptized Witnesses are ordained ministers and share in the preaching and teaching work. Witnesses are organized into congregations of about 100 believers. Spiritually mature men in each congregation serve as “older men,” or elders. (Titus 1:5) They do so without being paid for their services."
