"According to the Bible, marriage is heterosexual by definition. Jesus, when expressing his understanding of the scriptural foundation for the divine purpose and design in marriage, referred to its origins in the Creation account: “From the beginning of creation, God made them male and female. For this cause a man shall leave his father and mother, and shall cleave to his wife, and the two shall become one flesh…” (Mark 10:6-8, quoting Genesis 2:24)."
