As I explain in more detail in answer to the same question in another thread. That's mostly right. Jesus has always existed. He was conceived by the power of the Holy Ghost, and yes Mary was a virgin at the time (though after that she became a typical jewish mother/wife having other children).
So you took issue with the way that I phrased my question. I asked if you believed that Jesus Christ was conceived of the Holy Spirit instead of by the power of the Holy Spirit. That is perhaps where the breakdown in communication occurred. But Jesus in His (incarnation only) was (at the time that He became flesh i.e. human) Child of the Holy Spirit. Jesus Christ was conceived in Mary's womb and was described as being of the Holy Spirit (in stark contrast to being described as being of Joseph). The point: is that Jesus true Father is God and not Joseph. But this does not take anything away from the Lord Jesus. Remember: Jesus Christ has always existed. But He was not called Jesus until He became flesh (i.e. human). Jesus Name or appellation in eternity past was the Word. Actually Jesus had several designations in eternity during His pre-incarnation.
