Hey, so you did. You keep good notes. :) One question I don't think I was asking at the time is that if Mary had some sort of "quasi-marriage" to the Spirit, then why in the world would she have ever agreed to a traditional marriage to Joseph? Surely she had plenty of "brothers" to fill in the role of human father-figure to Jesus. If Mary agreed to be married with absolutely no intention of actually being a wife to Joseph, then how is she not guilty of fraud, a sin?
Joseph received his own revelation regarding Mary, so there was no fraud of any kind. The custom of temple virgins existed and their betrothal was practiced, albeit rarely; it did not imply or requre a sexual union. This is how the Protoevangelium of James describes it, -- note that it is clear that the marriage was not to be sexually consummated (emphasis mine):
And [Mary] was three years old, and Joachim said: Invite the daughters of the Hebrews that are undefiled, and let them take each a lamp, and let them stand with the lamps burning, that the child may not turn back, and her heart be captivated from the temple of the Lord. And they did so until they went up into the temple of the Lord. And the priest received her, and kissed her, and blessed her, saying: The Lord has magnified thy name in all generations. In thee, on the last of the days, the Lord will manifest His redemption to the sons of Israel. And he set her down upon the third step of the altar, and the Lord God sent grace upon her; and she danced with her feet, and all the house of Israel loved her.8. And her parents went down marvelling, and praising the Lord God, because the child had not turned back. And Mary was in the temple of the Lord as if she were a dove that dwelt there, and she received food from the hand of an angel. And when she was twelve years old there was held a council of the priests, saying: Behold, Mary has reached the age of twelve years in the temple of the Lord. What then shall we do with her, test perchance she defile the sanctuary of the Lord? And they said to the high priest: Thou standest by the altar of the Lord; go in, and pray concerning her; and whatever the Lord shall manifest unto thee, that also will we do. And the high priest went in, taking the robe with the twelve bells into the holy of holies; and he prayed concerning her. And behold an angel of the Lord stood by him, saying unto him: Zacharias, Zacharias, go out and assemble the widowers of the people, and let them bring each his rod; and to whomsoever the Lord shall show a sign, his wife shall she be. And the heralds went out through all the circuit of Judaea, and the trumpet of the Lord sounded, and all ran.
9. And Joseph, throwing away his axe, went out to meet them; and when they had assembled, they went away to the high priest, taking with them their rods. And he, taking the rods of all of them, entered into the temple, and prayed; and having ended his prayer, he took the rods and came out, and gave them to them: but there was no sign in them, and Joseph took his rod last; and, behold, a dove came out of the rod, and flew upon Joseph's head. And the priest said to Joseph, Thou hast been chosen by lot to take into thy keeping the virgin of the Lord. But Joseph refused, saying: I have children, and I am an old man, and she is a young girl. I am afraid lest I become a laughing-stock to the sons of Israel. And the priest said to Joseph: Fear the Lord thy God, and remember what the Lord did to Dathan, and Abiram, and Korah; how the earth opened, and they were swallowed up on account of their contradiction. And now fear, O Joseph, lest the same things happen in thy house. And Joseph was afraid, and took her into his keeping. And Joseph said to Mary: Behold, I have received thee from the temple of the Lord; and now I leave thee in my house, and go away to build my buildings, and I shall come to thee. The Lord will protect thee.

13. And she was in her sixth month; and, behold, Joseph came back from his building, and, entering into his house, he discovered that she was big with child. And he smote his face, and threw himself on the ground upon the sackcloth, and wept bitterly

15 [...] Joseph, whom thou didst vouch for, has committed a grievous crime. And the priest said: How so? And he said: He has defiled the virgin whom he received out of the temple of the Lord, and has married her by stealth, and has not revealed it to the sons of Israel
