Women are just as capable of receiving inspiration and guidance as men; the Lord is no respector of persons. But in relation to the priesthood, the Lord has withheld this from women. The Levites were all men. John the Baptist, who received the priesthood from his father, was a man; and the apostles were all men and all were ordained by Jesus. The two endtime prophets who will minister to the Jews during the battle of Armageddon aren't identified as men, and some women on the Internet have thrown their bonnets into the ring, claiming to be one of the prophets. (See Rev. 11)
In many of the early Christian apocraphal books discovered circa 1947 (and since), the scene is painted of the apostles being absolutely livid over the information Jesus shared with Mary. Indeed, in at least one of these works, Mary is identified as his "spouse." The point, though, is that there are things Jesus taught to the apostles, and apparently Mary as well, that pertained to the "mysteries of the Kingdom of Heaven." Just what these teachings are is moot, but what is not is that Jesus consistently kept Mary in his inner circle, often sharing things with her that he didn't tell the apostles. On occasion, the apostles went so far as to either try to get certain information from the Lord or tell them what the Lord had revealed to her. They apparently felt that because they were ordained, that they had an entitlement.
Women were never empowered to offer sacrifices, baptize, ordain, heal the sick or particiapate in the laying on of hands for the gift of the Holy Spirit. But at various times they were called to be prophetesses. But there's never been a documented case of a woman engaging in the ordinances listed above. But as far as being able to prophesy, receive revelation and so forth, there doesn't seem to be any limitations. Priesthood carries with it not only the power to preside, but the power to conduct ordinance work. And women are shown as having equal rights to salvation in the Kingdom of God, but not in priesthood authority.
My only beef is since everyone in the New Covenant is part of the priesthood of believers, why should there be a separate priestly class to begin with?
We have to look at the New Testament and not the teachings of the WBTS. There's actually no such thing as a "priesthood of believers." That's a complete misconception of scripture. The Jehovah's Witnesses teach that each baptized member is an ordained ministerial servant is a FALSE DOCTRINE and has no foundation in either scripture or tradition. The only priestly classes we see in the scriptures are the Levitical, or Aaronic, Priesthood and the Melchizedek, or Holy Priesthood, which many believe to be held only by Jesus and Melchizedek. The only office associated with this priesthood is that of High Priest; however, the Bible lacks a lot of information. Do elders have priesthood? If so, what kind? How about bishops, seventy, and priests? In fact, doesn't the term "priest" imply priesthood? As far as I know, the WTBTS does not claim to be a church. And there are no ordinations. As far as I'm concerned, that's a tacit admission of illegitimacy.
