Albert Barnes’ commentary: “If she should marry a heathen, would it not be showing that she had not as deep a conviction of the importance and truth of her religion as she ought to have? If Christians were required to be "separate," to be "a peculiar people," not "to be conformed to the world," how could these precepts be obeyed if the society of a heathen was voluntarily chosen, and if she became united to him for life? She would in this way greatly hinder her usefulness; put herself in the control of one who had no respect for her religion, and who would demand her time and attention, and thus interfere with her attendance on the public and private duties of religion, and the offices of Christian charity.”
