Article 223 - Slavery
Canon 2763 (link)
Slavery is without any valid moral foundation as it falsely claims a "divine right" of ownership between objects "owning" other objects which defies all known Divine Law, Natural Law and Positive Law.
Canon 2766 (link)
Unlike mandatory slavery, the voluntary slave system of "common law" does not disclose the full nature of its slavery and therefore fails the test of a lawful agreement in hiding terms, agreements and obligations thereby rendering any consent null and void.
Canon 2767 (link)
Slavery in all its forms, whether mandatory or voluntary is abolished in accordance with these canons and the sacred covenant Pactum De Singularis Caelum.
