Joseph the FATHER of Mary claim
Joseph the FATHER of Mary and GRANDFATHER of Jesus claim

So is the above statement correct ?

The Bible does not indicate that Joseph could have been the father of Mary, so we shall go to the Spirit of Prophecy to try to justify this claim.

Said Jesus, “How is it that ye sought me?” This pointed question was to lead them to see that if they had been mindful of their duty, they would not have left Jerusalem without him. He then adds, “Wist ye not that I must be about my Father’s business?” While they had been unmindful of the responsible charge intrusted to them, Jesus was engaged in the work of his Father. Mary knew that Christ did not refer to his EARTHLY FATHER, Joseph, but to Jehovah. She laid these things to heart, and profited by them. {RH, December 31, 1872 par. 8}

Even after he had proclaimed his divine relation to the Father, saying to his mother, “Wist ye not that I must be about my Father’s business?” he was still obedient to the claims of Mary and Joseph. For EIGHTEEN YEARS after he had declared himself the Son of God, he submitted to a life of toil, of restraint, yielding submission to the authority of his parents. He practiced self-denial, and WORKED WITH JOSEPH at the humble trade of a CARPENTER, thus forever dignifying toil. When we look upon his patient self-denial, his shrinking from all notoriety, devoting himself to his daily labor in a humble sphere, what a beautiful light is shed about his life! How clearly is pointed out the path in which children and youth should walk. If the youth would become strong in mind, pure in morals, firm in spiritual power, let them follow the example of Jesus in his simplicity, in his submission to parental restraint. For THIRTY YEARS his life was veiled in obscurity; yet Jesus was no less the Son of God in his lowly home, in his submission to HIS PARENTS, than when God spoke from his eternal throne, saying, “This is my beloved Son in whom I am well pleased.” Mrs. E.

The learned scribes and doctors were astonished at his wisdom, penetration, and mature judgment. The question passed from lip to lip, “How hath this youth this knowledge, having never learned?” Mary was rejoiced to find her son; but she could not forget the anxiety and grief which she had experienced on his account, and reprovingly she said, “Son, why hast thou thus dealt with us? behold, thy FATHER and I have sought thee sorrowing.” Christ respectfully lay back the censure, saying, “How is it that ye sought me? wist ye not that I must be about my Father’s business?” Mary knew that Christ did not refer to Joseph. In this assertion, he made it manifest that he did not recognize Joseph as his FATHER, but claimed God as his Father; and for the first time he spoke to them of the mission which he came on earth to fulfil. {YI, July 13, 1893 par. 2}
For twelve years of his life he had walked the streets of Nazareth, and worked with Joseph at his trade, carefully performing the duties that devolved upon a SON. Hitherto he had not given indications of his peculiar character, or made manifest the nature of his mission to earth as the Son of God. But upon this occasion he made known to his parents the fact that he had a higher, holier mission to perform than they thought, for he had a work to do which had been committed to him by his heavenly Father. Mary knew that Jesus had disclaimed relationship to Joseph, and claimed his sonship to the Eternal. She was perplexed; she did not fully comprehend the meaning of the words herself when he referred to his mission. She questioned in her mind as to whether any one had told Jesus that JOSEPH was not his true FATHER, but that God was his Father. Mary pondered these things in her heart. {YI, July 13, 1893 par. 3}

Before Christ came in the likeness of men, he existed in the express image of his Father. He thought it not robbery to be equal with God. Nevertheless he voluntarily emptied himself, and took the form of a servant. He was the incarnate God, the light of heaven and earth. In him are hid all the treasures of wisdom and knowledge. Yet he was born in a stable, in Bethlehem of Judea. He was the son of Mary, supposed to be the SON of Joseph, and he grew up as any other child. His earthly life was one of self-denial and self-sacrifice. “The foxes have holes,” he said, “and the birds of the air have nests; but the Son of man hath not where to lay his head.” {YI, December 20, 1900 par. 4}

Honor thy father and thy mother,” is one of the commands spoken from Mount Sinai. It is the only one of the ten to which a promise is attached,–“That thy days may be long upon the land which the Lord thy God giveth thee.” Jesus was the Son of God; yet the Bible record tells us that he was subject to his earthly parents, Joseph and Mary, the humble peasants of Galilee. He did as he was told, even when the task assigned him was not agreeable to his feelings. {YI, September 24, 1884 par. 1}

In trying to justify the claim against the quotations we find that we would have a number of serious problems:
1. Jesus would not have lived and grown up as a typical boy. He would have been a “special case” and therefore not our ideal example to follow.
2. All Biblical and Spirit of Prophecy references cite that Jesus had his earthly father as Joseph.
3. Jesus respected Joseph as his father.
4. Society spoke of Joseph being the father of Jesus.
4. Sons often followed in the trade of their father. For Joseph to have been a grandfather then he would have had to live a very look time and with an abnormally long working life. This is needed to cover the “30 year” lifespan of Jesus where he was worked as a carpenter with Joseph for 18 years. Again, this is not the typical case and would have attracted attention.
