In the Bible, those who are charged with oversight of a congregation are described being males. The 12 apostles of Jesus Christ were all males, and those later appointed to be overseers and ministerial servants in Christian congregations were males. (Matt. 10:1-4; 1 Tim. 3:2, 12) Women are counseled to "learn in silence with full submissiveness" at congregation meetings, in that they do not raise questions challenging the men in the congregation. The women are ‘not to speak’ at such meetings if what they might say would demonstrate lack of subjection. (1 Tim. 2:11, 12; 1 Cor. 14:33, 34) This arrangement is in accord with the headship principle stated at 1 Corintians 11:3, where it says,"But I want YOU to know that the head of every man is the Christ; in turn the head of a woman is the man; in turn the head of the Christ is God." Going further, that same chapter at verse 8 (alluding to the creation of Eve form the rib of Adam) says,"For man is not out of woman, but woman out of man"
This in no way is demeaning to women, or gives the man permission to abuse his headship for 1 Peter 3:7 says, "YOU husbands, continue dwelling in like manner with them according to knowledge, assigning them honor as to a weaker vessel, the feminine one, since YOU are also heirs with them of the undeserved favor of life, in order for YOUR prayers not to be hindered." So if a husband fails to command to assign honor to his wife, in other words, treat her with kindness, then his prayers to God would be "hindered" or ignored by God.
Being under headship is not in itself demeaning. Headship contributes to the handling of matters in an orderly arrangement, and Jehovah is "a God, not of disorder, but of peace." (1 Cor. 14:33) Jesus Christ is under the headship of Jehovah God, and he finds great satisfaction in that relationship.—John 5:19, 20; 8:29; 1 Cor. 15:27, 28.
But women may be preachers, proclaimers, ministers of the good news, outside the congregation meetings. In the Bible, all Christians are commanded to be preachers of the good news, and this preaching work would be a sign of the "last days" that Jesus talked about. (Matthew 24:14; 28:19,20). In the first century Christain congregation, there was no paid clergy class. All were preachers. At Pentecost of 33 C.E. holy spirit was poured out on both men and women. In explanation, the apostle Peter quoted Joel 2:28, 29, saying: "‘In the last days,’ God says, ‘I shall pour out some of my spirit upon every sort of flesh, and your sons and your daughters will prophesy and your young men will see visions and your old men will dream dreams; and even upon my men slaves and upon my women slaves I will pour out some of my spirit in those days, and they will prophesy.’" (Acts 2:17, 18) In like manner today, women properly share in the Christian preaching of the good news outside of the congregation. In this way, the truest sense of the term "preachers," they ARE preachers.
