Is it not also reasonable that Mary simply called the child "a supernatural cause" due to the extreme shame and ostracisation that would be involved with having sex and giving birth outside of marriage (especially with regards to the context of the time)?

If Jesus = Jeshua = God saves, how does Jesus = Immanuel = God with us? IS Immanuel a title like Christ? Or does God saves = God with us?

How is Jesus both Yeshua and Immanuel? Does he have two names?

Could Isaiah 9 indicate you could expect a baby to come to bring hope? God the Father?" 

Why much more emphasis on Mary instead of Joseph throughout the Bible, besides this bit in Matthew 1?
