In the Bible as the inspired, inerrant Word of God, giving us God's plan for salvation and the Christian life.
Genesis 3, Romans 3:23, Ephesians 2:8-9
That the term “marriage” has only one meaning: the uniting of one man and one woman in a single, exclusive union, as delineated in Scripture. That God intends sexual intimacy to occur only between a man and a woman who are married to each other. That God has commanded that no intimate sexual activity be engaged in outside of a marriage between a man and a woman. God’s pattern for marriage.
