Paschang

A division somewhat more to the point might be made: 1.Ratione Institutoris; 2. Ratione Objecti; 3.Ratione Ministri; 4.Ratione Formae; (5. Repeatability).

- John L. Paschang, Sacramentals According to the Code of Canon Law. (Washington, D.C.: Catholic University of America, 1925), 10.

Though I don't include all the information in each heading, this division is very useful because, while many authors of entries on sacramentals in moral theology manuals use a division, it is not always explicit nor as thorough. Paschang's overview of the subject, while focused on Canonical import, gives a "wholistic" view of canon law, that there is actually a theological consequence, a science is employed when forming the laws.

Also this is from before SC and the new code (whose commentators cite SC) so when trying to elaborate the meaning of the analogy, he doesn't stop at citing authority.
