Q. 1. Where does it say in the Bible that a union has to be between a man and woman?
A. 1. In the Book of Genesis, it states, "God blessed them, and God said to them, 'Be fruitful and multiply, and fill the earth and subdue it.'" [Gen. 1:28] In the next Chapter, it states, "Therefore a man leaves his father and his mother and clings to his wife, and they become one flesh." [Gen. 2:24]
Nowhere in the Holy Bible does it state that a union as defined in a marriage is between two persons of the same gender.
A union between a man and a woman produces offsprings in accordance to the Divine Plan.
A union between two persons of the same gender produces sexual pleasures that cannot parallel sexual intercourse that produces offsprings.
