Where's the other side?

After this week's class I was really wanting to hear the other side to the argument that Sarah had presented. Our guest speaker shared with us her interpretations of the 1 Timothy passage and had everything laid out with the Greek translations. She had a great and developed argument for her side but my question is if her side is so strong how can there be another side of it? I understand that there are two sides to an argument always but am at a loss for what it is in this situation. I also believe that it is important to know the other side in order to defend or keep your own opinion in the first place because if you don't know about it how can you know it is wrong? So I am now very curious to hear the other side and what she would say to someone who thinks that way, opposing to her views.
Another piece that I really struggled with this week was biblical interpretations. Each time someone reads the Bible they understand it differently from the other person who reads it also. But my question is when do we doubt the scripture and when do we take it for what it says. I feel really scared when people begin to take apart the Bible and question it's authority. For me personally I believe 100% that the Bible has been divinely inspired and yes it did come through the vessel of man but God gave the words to man. I am very weery of this idea that we can just say that something in the Bible was merely interpreted wrong or no longer applicable to our lives because the Bible in itself is essentially the road map that we need to know where God wants us to go in our lives. Of course there is no exact passage telling you what to do but the Holy Spirit will speak to you through the scripture you are reading, to me this is just such an important part of my faith that it seems so worrying to me to begin to take it apart and analyze it's authoritativeness. My question I am still left with is: when do we know when to doubt the scriptures and when do we know to trust it for what it is saying? If you begin to pull it apart and take things away as not true then when does it stop? How can we so long after truly know what is supposed to be there and not, I think it is through faith that we believe God will use the Bible to speak into our lives even if it is not 100% the way he initially wanted it to be. I mean look at us we are sinners who God created to be perfect in the beginning but chose not to be yet He still uses us. That shows me that there is hope in this life for all things we just need to have faith that God will come through and help us wade through the mud to understand what is truly important to our lives today.
