“Just as Jesus is literally the Son of Mary, so he is the personal and literal offspring of God the Eternal Father. …Matthew’s statement, ‘she was found with child of the Holy Ghost,’ properly translated should say, ‘she was found with child by the power of the Holy Ghost.’ (Matt. 1:18.) …Alma perfectly describes our Lord’s conception and birth by prophesying: Christ ‘shall be born of Mary, … she being a virgin, a precious and chosen vessel, who shall be overshadowed and conceived by the power of the Holy Ghost, and bring forth a son, yea, even the Son of God.’ (Alma 7:10.)”
