Marriage is more than love

"Your love is your own private possession, but marriage is more than something personal—it is a status, an office. Just as it is the crown, and not merely the will to rule, that makes the king, so it is marriage, and not merely your love for each other, that joins you together in the sight of God and man. … So love comes from you, but marriage from above, from God.”

-- Dietrich Bonhoeffer, Letters and Papers from Prison (1953), 42–43.
