So it is no longer inevitable. Good to know. Also no it is not a sign of mistrust. Sweet Jesus. If it was mistrust would they be allowed to give talks during religious services, lead groups in prayer, teach gospel lessons, be placed in positions of authority over the youth of the church in many cases? No they would not.
Is every male who gives a talk a bishop, or does the office of bishop indicate a higher level of trust than that of speaking to the congregation (I honestly don't know the answer)? Even for the JWs, where women are not allowed to speak to the congregation as a whole, have women engage in a public talk with each other while on a stage in from of the congregation. Does that make their rule not misogynistic?
As for the other three, you see them in even the most oppressive of religions.
Do you know why women are not allowed to be bishops? What's the basis, besides a lack of trust that a woman can handle the role?
