Jesus Christ, said Strang, was the natural-born son of Mary and Joseph, who was chosen from before all time to be the Savior of mankind, but who had to be born as an ordinary mortal of two human parents (rather than being begotten by the Father or the Holy Spirit) to be able to truly fulfill his Messianic role. Strang claimed that the earthly Christ was in essence "adopted" as God's son at birth, and fully revealed as such during the Transfiguration. After proving himself to God by living a perfectly sinless life, he was enabled to provide an acceptable sacrifice for the sins of men, prior to his resurrection and ascension.
