Nevertheless, although a distinction between lawful and unlawful hunting is undoubtedly permissible, it is certain that a bishop can absolutely prohibit all hunting to the clerics of his diocese, as was done by synods at Milan, Avignon, Liège, Cologne, and elsewhere. Benedict XIV (De synodo diœces., l. II, c. x) declared that such synodal decrees are not too severe, as an absolute prohibition of hunting is more conformable to the ecclesiastical law. In practice, therefore, the synodal statutes of various localities must be consulted to discover whether they allow quiet hunting or prohibit it altogether.
What distinction is undoubtedly permissible?
