Latin. Concerning sacred things. About or concerning sacred things. The civil courts have a certain jurisdiction in sacred (or rather, and more correctly, ecclesiastical) matters, as in questions of presentation by a patron ; but it has no jurisdiction in sacris, i.e., such questions as ecclesiastical discipline, or questions of doctrine. In such questions the church has supreme jurisdiction. See the case of Lockhart, 5th July 1851, 13 D.
