Sorry, I thought I clicked on the "Islamophobia in the CF" thread by mistake. All good.
Sorry to break it to you and your wife, but in Islam you are supposed to believe in the whole Qur'an (whether the chapter was revealed in Mecca or Medina). Of course rulings have to take account the current time and location and given by a qualified Imam/Mufti.
Also, in mainstream Sunni islam, a Muslim woman is prohibited from marrying a non-Muslim man (I'm just stating facts). So nothing is adding up in your post.
Anyhow, I recommend you tag along with your wife when she goes to her mosque next time and pose any questions you have to the local Imam there. There are plenty of mosques in Vancouver.
Peace upon you.
