"The Deity" as meaning also Heavenly Parents --> The "supreme governing power" of Lecture 2 as the Noomatic Genome of the Father's personage of spirit and the personage of spirit of the divine Heavenly Mother
Mary --> The prototype of Heavenly Mother, see 1 Nephi 11:15, Lecture #7 and D&C 132
D&C 132: They (male and female) shall be gods because they (as basically Supercouples) continue spreading the Divine Gene, just like their Heavenly Parents reproduced in them their divine genus; thus bringing to pass the eternal lives (continuation of seed/genes) of mankind divinizedin Christ as holy ones (gods)
Just as Jehovah appeared as the Angel of Lord as the Father God, as a personage of spirit in the Old Testament. God's wife, Heavenly Mother is represented through Tree imagery and the Wise Lady/Sophia metaphor (e.g. Luke 7:35); and the Eros-like Song of Solomon celebrating the passionate coupling of the sexes.
