Claim. The Holy Wine ceremony is the first stage of lineage change: a re-enacted Fall reversed, in which the woman receives wine first to indemnify Eve’s prior fall and the wine itself draws out Satan’s blood.
Elaboration. SMM specifies the function: “Through this ceremony, one can be cleansed of the original sin by inheriting the new lineage centering on the love and substantial aspect of God. You cannot go to the place of the Blessing without attending this ceremony. That is why the holy wine ceremony is a ceremony for changing the lineage” (2.4. Three stages in changing the lineage, 35-245, 1970.10.19). The order is reverse-of-Fall: “Without Eve, the man cannot be reborn. Because the purpose of drinking the wine is restoration, Eve must receive the holy wine first, drink half of it, and then offer the remaining half to her husband” (ibid, 183-89, 1988.10.29). The function is purgative: “The holy wine ceremony draws out the blood of Satan, the blood that was defiled through the Fall. In other words, it is a ceremony that draws out the original sin” (ibid, 35-215, 1970.10.19). The post-ceremony stakes are absolute: a person who receives the wine and then sins “defiles the substantial body of God in the perfection level of the completion stage and cannot ever be forgiven” (ibid, Blessed Family 596).
