The use of law in Middle English literature is not extraneous but grows naturally out of a profound faith in law as the tie that binds all things, in heaven and in earth: all law—divine, natural, and human—is, in essence, one law. Hence, Christ's victory over Satan is dramatized in the language of Westminster, the promise of salvation is seen in terms of the emerging law of contracts, and our place in heaven is treated as real estate. The process is seen most clearly in the Château d'Amour, Piers Plowman, Pearl, and “Quia Amore Langueo.” With the disintegration of the belief in a single, coherent law, however, the legal metaphor lost most of its force and economy. As heirs of that disintegration, we must be careful not to impose it unwittingly on Medieval literature and thus fragment a vision that was whole.
