Hints of the LDS concepts of pre-existence in the early church and God the Father is married:
An early Christian poem known as “The Pearl,” for example, begins: “In my first primeval childhood … I was nurtured in the royal house of my Father. … Then my parents sent me forth from our home in the East (the source of light), supplied with all necessities. … They removed from me the garment of light … and they made a Covenant with me, and wrote in my heart, lest I go astray.” 33

"in the great old Manichaean Song Book, Adam is received by a happy family on his return. On the other side, they have awaited him in high expectation, or the return of the first man with news from him. They have eagerly awaited news of Adam's victory, of the success of his mission; and they want to hear it from his own lips when he returns. On his part, Adam, being away from home, asks a Newsbearer of the Skies, as he is called, ""How is my Father, the Father of Light? How is my Mother,. the mother of the living whom I left, and her brethren also? Rejoice with me, ye holy ones, for I have returned to my original glory again." And again, in leaving the earth, he says, "My hour has come. They summon me. I will go from your midst and return to my true home." Accordingly, "The Sent One comes to take the soul of Adam back to the great first house of his Father to the place where he formerly lived." And so his children were admonished, "Arise, old soul, return to your original home, to the place from which you were planted. Put on your garment of glory. Sit down upon your throne. Dwell in the dwellings among the Uthras, thy brethren." And again, "Now arise and return to the place of thy family." "I came from the house of my Father," the Psalm of Thomas, "in a far land, and I shall mount up until I return to that land of the pure." There is a moving scene at the end of the Pearl, the most moving of all the early Christian Syriac writings, where the hero finally returns to his home, his mission accomplished. He's met at the gate of greeting and honor by his entire family. He bows and worships his father and the Christ of the Father "who has sent me the garments and given me the orders while I was on the earth." All the princes of the house were gathered at the gate. They embraced him with tears of joy as the organ plays and they all walk back to the house together."
And Gregor of Nyssa, one of the three great Cappadocians, writing about this, says that in his time, the Fourth Century, the church was very confused about these teachings. They were being rapidly lost. He says, "Christians are all confused about the preexistence. Some say we lived in families there, and in tribes just as we do here, and that we lost our wings when we came down here and will get them back again upon earth." So they mix up tenable and untenable things; all sorts of strange ideas get in the picture. Regardless of what the true picture is, we know that the early Christians did believe very strongly in the preexistence. The mysterious word propators, which they used a lot, is now recognized as not meaning the Father who was before our Heavenly Father but our Heavenly Father as our forefather, our propator---"the father of our preexistent spirit," says a quotation from a newly found work. "When they ask you who you are," says the Apocryphon of James, "say 'I am a son and I come from the Father.' And when they ask you what sort of son and from what father, answer, 'From the preexistent Father and I am a son of the Preexistence-' .... The spirit existed before the flesh," says a psalm. Commenting on the teaching of this doctrine, the Clementine Recognitions, the editors of the Patrologiae Graecae note that various fathers of the church represented every interpretation of the doctrine, from absolute acceptance to absolute denial. Most of the fathers temporized somewhere in between. Again, this is a good indication that we are dealing with an authentic teaching of the early church, since the early fathers are all for it. The later ones don't know; they are not so sure.-Old Testament and Related Studies-Nibley
