Two dominant issues stand out with respect to Unification Thought views on sexual reproduction.
Why sexual reproduction?
The issue of why sexual reproduction has appeared and is so prevalent is one of the great mysteries of biology. Among animals, and indeed eukaryotes in general, sexual reproduction is a nearly universal mode of reproduction. Mayr (2001) notes that since the 1880s evolutionists have argued over the advantage of sexual reproduction and "so far, no clear-cut winner has emerged from this controversy."
Rev. Moon has addressed this topic as well. In 1981 (Family Magazine), he said the following:
- ”If there is a most arcane mystery in the world of beings, it is that man and women have come into existence, and that male and female in animals have come into existence. Furthermore, in the plant world, there are stamen and pistil; and in the mineral world, there are cation and anion. In this way, everything has been made according to the pair system. Man and women, male and female—the reason why things exist in this way is the mystery of mysteries.”
Unification Thought holds that science seeks to clarify the causality of things, but this issue of is related to the reason “why” of things—an issue more appropriate to the realm of philosophy. From the point of Unification Thought, male and female came into existence because they were created in the likeness of the Creator. That is, as expressed in Unification Thought, “God is the united body (or harmonized body) of Yang and Yin” (masculinity and femininity). Taking this further, yang and yin exist for the purpose of love. Male and female in animals, stamen and pistil in plants, cation and anion in minerals—while external needed for reproduction and maintenance—were created for the purpose of giving and receiving love.
Human sexual reproduction
Human sexual reproduction has also been controversial. Many discourses, including some Wikipedia articles and discussions, give the impression that as far as human sexuality, "anything goes." Even the classification of humans as a monogamous species has been under attack. Furthermore, there is effort to utilize social Darwinism and extrapolate from behaviors in the animal world to try and explain human sexual reproduction. Thus, one gets such views as that (1) men are naturally promiscuous, because they wish to spread their genes widely, while women are naturally monogramous, because they have to invest a lot of time and energy into each pregnancy and rearing of the child, and thus they also seek men that are monogamous and faithful; (2) women are naturally promiscuous, "genetically programmed to have sex with several different men in order to increase the chances of healthy children with the greatest likelihood of survival" (although the pair male may be raising the child). From the first view, there is also the ancillary concept that with birth control, there is no longer a need for women to be monogamous. These views have left the realm of biological speculatation (for, of course, they are speculation) to dissemination by the mass media.
If one looks at things externally, one can certainly get the view that the human species is not sexually monogamous. However, this perspective ignores two realities.
One reality is that humans are not just physical beings, but also spiritual beings. Religions around the world recognize humans as endowed with a spirit and recognize the sanctity of marriage and fidelity in marriage. According to a number of religions, the phenomena observed in the human world is the result of the "Fall of Man," rather than the ideal design, and thus is a deviation from the character of a true man and true women.
Secondly, it is not justified to extrapolate from the natural world to humans. For one, humans are unique. Even their reproductive systems are set up different than most mammals, displaying signs of availabilty and secondary sexual characteristics not only "when in heat," when the female can get pregnant, but at all times. In addition, is it really justified to extrapolate from jungle fowl, bees, fish, and so forth? It is certainly problematic to compare mating habits of species in creation with human habits, given that people are endowed with a spiritual as well as physical nature. (See human and human body.) While the comparison is unjustified, perhaps, the dominance of monogamy in birds and some primates, and the extensive phenomena of pairing for life as a universal standard within certain of these species, provides a counterbalance to the current social Darwinistic views of some that monogamy, pairing for life, and fidelity in humans is an unnatural state.
From the point of view of Unification Thought, man and women come together in union and
make a unified whole. When centered on God, these four elements—God, man, women, and the unified whole (family, or new creation) represents a four-position foundation.
