If anyone wants us to be perfectly literal about 1 Tim 2:12, we should note, at least as a beginning, that Paul is primarily speaking against one-on-one mentoring, female to male. "I do not allow a woman to teach or to direct a man." Everything in this statement is entirely singular. In other words, according to the strictest possible interpretation of 1 Tim 2:12, Paul could have approved of Priscilla teaching Apollos, because the prudent woman had her husband assist as she explained the way of God to a transient single male. (There's a sister with wisdom, eh?)
Ah, but the context! Verses 13 & 14 are clearly negative toward women, aren't they? Again, strictly speaking, they're negative toward one woman. Eve. So - at the very least - before we debate how broadly Paul expected Timothy to apply these statements, it's worth noting that vv. 13 & 14 keeps everything singular in number. In explaining his strict directive against one-on-one female-to-male discipleship, Paul reviews the case of the very first such case.
Whatever else Paul is saying, Eve & Adam were a particular one-on-one partnership, in which he followed her right into sin. In other words, Paul's illustration retains the singular intimacy of his prohibition. This may not be a coincidence. The male/female intimacy of a one-on-one discipling relationship may be all Paul is really afraid of.
Could it really be just that simple? Let's try to dig a bit harder.
