De Processione Spiritus Sancti (On the Procession of the Holy Spirit)

Major medieval-scholastic-systematic-theological work.

"The proper-philosophical-theological analysis of the procession of the Holy Spirit requires careful conceptual work; the dialogue develops this." (De Processione)

Foundational Latin-Western systematic-theological text on the filioque controversy.

"The Latin-Western position on the procession — filioque — is what the treatise systematically defends; subsequent Catholic-Thomistic work develops this framework." (Standard scholarly account)

Engages — and substantially rejects — the Greek-Orthodox position on the procession.

"The Greek-Orthodox position — proper-procession only from the Father — is what the treatise systematically rejects; the East-West controversy is at its philosophical-theological heart here." (De Processione)

Strong philosophical-rational-argumentative framework — philosophical reasoning on Trinitarian theology.

"What philosophical reasoning can establish about the proper-Trinitarian relations is what the treatise develops; the rationalist-philosophical method is essential." (De Processione)

Foundational medieval source for modern analytic-philosophy-of-religion conversation on Trinitarian theology.

"The modern analytic-philosophy-of-religion conversation on Trinitarian theology engages Anselm's framework as foundational source." (Standard modern scholarly account)

Natural-philosophical-theological framework — the proper-Trinitarian relations as proper-philosophical-theological subject.

"The proper-philosophical-theological analysis of the Trinity requires both natural-philosophical-rational work and revelation-historical work." (De Processione)

Strong critical-philosophical engagement with the Greek-Orthodox arguments.

"The proper-philosophical work requires sustained engagement with the specific Greek-Orthodox arguments; the treatise undertakes this." (De Processione)
