“God” Was the Son of Joseph: “Philip findeth Nathanael, and saith unto him, We have found him, of whom Moses in the law, and the prophets, did write, Jesus of Nazareth, THE SON OF JOSEPH,” (John, 1:45)
Brothers and Brothers-in-law of “God”: “And when he was come into his own country, he taught them in their synagogue, insomuch that they were astonished, and said, Whence hath this man this wisdom, and these mighty works? Is not this the carpenter’s son? is not his mother called Mary? And his brethren, James, and Joses, and Simon, and Judas? And his sisters, are they not all with us? Whence hath this man all these things?” (Matthew, 13:54-56).
