Matthew 19:4-6
From Wesleyan Discipline
19:4 “Haven’t you read,” he replied, “that at the beginning the Creator ‘made them male and female,’ 19:5 and said, ‘For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh’? 19:6 So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate.”
