Jesus' Incarnation Counsel Regarding Marriage
While you will live the normal and average social life of the planet, being a normal individual of the male sex, you will probably not enter the marriage relation, which relation would be wholly honorable and consistent with your bestowal; but I must remind you that one of the incarnation mandates of Sonarington forbids the leaving of human offspring behind on any planet by a bestowal Son of Paradise origin. (120:3.8)
From his 20th year:
It was during this year that Mary had a long talk with Jesus about marriage. She frankly asked him if he would get married if he were free from his family responsibilities. Jesus explained to her that, since immediate duty forbade his marriage, he had given the subject little thought. He expressed himself as doubting that he would ever enter the marriage state; he said that all such things must await "my hour," the time when "my Father's work must begin." Having settled already in his mind that he was not to become the father of children in the flesh, he gave very little thought to the subject of human marriage. (127:6.8)
From The Story of Rebecca
After listening attentively, he sincerely thanked Rebecca for her expressed admiration, adding, "it shall cheer and comfort me all the days of my life." He explained that he was not free to enter into relations with any woman other than those of simple brotherly regard and pure friendship. He made it clear that his first and paramount duty was the rearing of his father's family, that he could not consider marriage until that was accomplished; and then he added: "If I am a son of destiny, I must not assume obligations of lifelong duration until such a time as my destiny shall be made manifest." (127:5.5)
Said Jesus, on Marriage and Family:
Marriage is honorable and is to be desired by all men. The fact that the Son of Man pursues his earth mission alone is in no way a reflection on the desirability of marriage. That I should so work is the Father's will...
...it is the divine will that men and women should find their highest service and consequent joy in the establishment of homes for the reception and training of children, in the creation of whom these parents become copartners with the Makers of heaven and earth. And for this cause shall a man leave his father and mother and shall cleave to his wife, and they two shall become as one. (167:5.7)
[Jesus taught]...a child is wholly dependent on his parents and the associated home life for all his early concepts of everything intellectual, social, moral, and even spiritual since the family represents to the young child all that he can first know of either human or divine relationships. The child must derive his first impressions of the universe from the mother's care; he is wholly dependent on the earthly father for his first ideas of the heavenly Father. The child's subsequent life is made happy or unhappy, easy or difficult, in accordance with his early mental and emotional life, conditioned by these social and spiritual relationships of the home. A human being's entire afterlife is enormously influenced by what happens during the first few years of existence. (177:2.5)
"My brother, always remember that man has no rightful authority over woman unless the woman has willingly and voluntarily given him such authority. Your wife has engaged to go through life with you, to help you fight its battles, and to assume the far greater share of the burden of bearing and rearing your children; and in return for this special service it is only fair that she receive from you that special protection which man can give to woman as the partner who must carry, bear, and nurture the children. The loving care and consideration which a man is willing to bestow upon his wife and their children are the measure of that man's attainment of the higher levels of creative and spiritual self-consciousness. Do you not know that men and women are partners with God in that they co-operate to create beings who grow up to possess themselves of the potential of immortal souls? The Father in heaven treats the Spirit Mother of the children of the universe as one equal to himself. It is Godlike to share your life and all that relates thereto on equal terms with the mother partner who so fully shares with you that divine experience of reproducing yourselves in the lives of your children. If you can only love your children as God loves you, you will love and cherish your wife as the Father in heaven honors and exalts the Infinite Spirit, the mother of all the spirit children of a vast universe." (133:2.2)
