One other thing I forgot to mention. One of their main doctrines is "Everything we teach is written in the bible, nothing comes from other sources like the rosary beads of the catholics for example" so in that instance if he were to get into a debate with me, he would
have to use the bible to prove his point. Any citing of an apologetic would be admitting the bible has contradictions.
That sounds good if they will actually stick strictly to the Bible although someone exceptionally well versed in the Bible can pick parts out that can be conversation stoppers. You can't reason with the unreasonable. And he need not cite any apologetics in order to make the argument himself. No matter what anyone says, the Bible must be interpreted. He can tell you that "verse X means Y" and all you can do is say, "no it doesn't" and then you have a conflict of interpretations. Which one will he go with, yours or his?
They quoted the bible during the marriage that the man is the head of the household and that women shall have no authority over man.
Wives are to submit to their husbands and learn in silence. They quoted this literally so why can I quote the rest?
You may be able to quote that to your wife. However, the Bible also says "Do not be unequally yoked with unbelievers. For what partnership has righteousness with lawlessness? Or what fellowship has light with darkness?" —2 Corinthians 6:14 They could tell your wife that you are an unrighteous unbeliever and that nullifies what it says about submitting to her husband. They might also use Deuteronomy 7:3-4 "You shall not intermarry with them, giving your daughters to their sons or taking their daughters for your sons, for they would turn away your sons from following me, to serve other gods. Then the anger of the Lord would be kindled against you, and he would destroy you quickly."
Believe me when I tell you that you have to be very well versed in the Bible to compete with people who make it their lives. If you take on one of their ministers head to head and he makes you look foolish, how will this help you with your wife? If you go this route, here is a verse to remember: 1 Corinthians 7:13-15 "And if a woman has a husband who is not a believer and he is willing to live with her, she must not divorce him. For the unbelieving husband has been sanctified through his wife, and the unbelieving wife has been sanctified through her believing husband. Otherwise your children would be unclean, but as it is, they are holy. But if the unbeliever leaves, let him do so. A believing man or woman is not bound in such circumstances; God has called us to live in peace."
Like I said, the Bible has many conflicts and it is possible to interpret any verse in multiple ways. Since there are conflicts, religions decide which parts supersede other parts. It is a tricky game and they hold more cards than you.
