Summa of Saint Raymond of Penyafort of the Order of Preachers
Sancti Raymundi de Pennafort, Ordinis Prædicatorum, Summa
Summa of Raymond of Penyafort (c. 1175–1275), the Catalan Dominican canonist and Master General of the Order of Preachers, augmented with the full text of the sacred canons cited therein. Raymond's Summa — composed c. 1224–1234 — is a systematic handbook of penitential and matrimonial law organized in four books: the first three covering simony, usury, homicide, theft, and related moral and canonical matters for use in the confessional; the fourth treating matrimony. This 1744 Verona edition, revised against manuscript sources, was prepared under the direction of the Dominican Order and printed at the Seminary Press by Augustino Carattonius.

Readings
On Masters, and that they should not exact anything for a license to teach
De Magistris, & ne aliquid exigant pro licentia docendi
Raymond's treatment of teaching licenses in Book 1, Title 3 of the Summa. Drawing on papal decretals of Alexander III (Prohibeas, Quanta), it prohibits masters and chancellors from demanding any payment for the licentia docendi, treating such licenses as annexed to spiritual goods and therefore subject to the law against simony. Discusses what compensation teachers may lawfully receive (voluntary offerings, expense recovery), addresses the chanceries of Paris and Bologna, and considers the bishop who withholds a cleric's license to study unless paid.

De Simonia
Raymond's treatment of simony in Book 1, Title 1 of the Summa. Defines simony as the deliberate will to buy or sell a spiritual thing (§. I), covers the various modes of committing it — by gift, service, or flattery — and distinguishes licit from illicit transactions involving ecclesiastical offices, ordinations, benefices, and patronage rights. Addresses penalties for simoniacs and conditions for dispensation, with extensive citation of the Decretum and Decretals.
