Canon IV
They who are of the sacerdotal order ought not to lend and receive usury, nor what is called hemioliæ.
A priest is not to receive usury nor hemioliæ.
The same rule is laid down in the seventeenth Canon of Nice. For a treatment of the whole subject of usury see excursus to that canon.
Dionysius Exiguus and Isidore have numbered this canon v., and our fifth they have as iv.
This canon is found in the Corpus Juris Canonici, Gratian’s Decretum, Pars I., Dist. XLVI., can. ix.
