What does it mean spiritually for the person who receives holy wine?
Father, Rev. Yang, Rev. Kwak, Rev. Jenkins have all written about the value and meaning of Cheon Il Guk Holy Wine and you can read their guidance here. Basically, the holy wine is connected to the change of blood lineage. Although a couple does not become a “Blessed Couple” simply by drinking holy wine, it’s the beginning of the process for them to change the blood lineage. Rev. Kwak refers to this stage as “Pre-Blessing.” Once people take the holy wine, they are removed from Satan’s dominion, consequently, the foothold of Satan disappears and our second and third generations and our further descendants will be able to live freer and safer lives.
