Actually sully, your comment that God didnt make Mary pregnant is heresy. From the creed: "by the power of the Holy Spirit he was born of the Virgin Mary" and from the Gospel of Luke: The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God."  if that isn't God making her pregnant I don't know what is.  

By the way, I never said that I did or did not nelieve this.  I only said that one could arrive at this conclusion from Catholic theology and Scripture.  Personally I have no opinion either way.  Most, if not all theology is idle speculation and really serves little purpose.  IMHO
