First, yes, I am qualified. I have a PhD in New Testament Studies with an emphasis on Greek language and translation. Most English translations simply follow a high church tradition, when they translate the Greek "authentein" as "authority". And that misses the point. It is a negative word for domineering attitude, not a positive one for at least somehow beneficial authority (which would be "exousia").

For 1 Tim 2:12, see http://www.patheos.com/blogs/bibleandculture/2015/06/02/why-arguments-against-women-in-ministry-arent-biblical/

The explanation is way too long to be written here.
