There isn't room enough here to answer all your questions. So I'll deal with the first and suggest you do some research on your own for answers to your remaining questions. This answer also ties in with your question #9. Paul was not forbidding women ever to speak at all, as many presume, or else why would he have admonished them to wear a head covering when praying and prophesying? (1 Corinthians 11:5-6) The context of 1 Corinthians 14:34 is orderly worship, and the Greek word translated “speak” means to talk, question, argue, or chatter. These are disruptive actions of which some women in the church at Corinth were guilty. In support of this, in 1 Corinthians 14:35 Paul said that if ever they didn’t understand what that was going on, or had a contrary opinion about something being said, they should wait and discuss it with their husbands when they got home. The definition for “speak” specifically did not prohibit singing, praying, prophesying or public speaking, which women, like men, have always been welcome to do in the church as long as it’s done in an orderly manner. Beginning in 1 Cor. 11 Paul’s focus was on orderly worship, so everything has to be looked at in that light. And as you study all of Paul’s writing on the marriage relationship, you’ll see that he always differentiated between equality and submission. There’s never a hint of male superiority, either in what he did or what he wrote. In fact the entire New Testament is one of the most liberating documents ever written for women. But from the beginning, there has been an order in creation that calls for man to be submissive to God and woman to be submissive to man. For example, Jesus is equal to God in every way, but when He became a man He placed Himself in submission to God. (Phil. 2:6-7) That’s what Paul meant by obeying the law. His point was that out of respect for God, it’s especially important for this order to be maintained in worship. In 1 Cor. 11:5 Paul recognized that women would take part in worship, so that’s not the issue. And voluntary submission to her husband obviously doesn’t apply to single women. Paul’s instruction only seems strange to us because of the misguided notion that in order for women to be equal to men, they cannot be submissive to their husbands.
