What is the meaning of these words "He was conceived by the Holy Ghost, born of the virgin Mary"?
That God's eternal Son, who is, and continues1 true and eternal God,2 took upon him the very nature of man, of the flesh and blood of the virgin Mary,3 by the operation of the Holy Ghost;4 that he might also be the true seed of David,5 like unto his brethren in all things,6 sin excepted.7
