Occasion. The sixth of the twenty-five Public Disputations printed in the Opera and in Nichols's English, defended under Arminius by the respondent whom Nichols prints as James Mahot. It is not among the seven also printed in the 1615 Syntagma. It follows the disputation on the Father and the Son, and takes up the Third Person of the Trinity.
The doctrinal move. After a short preface linking it to Disputation V, the disputation fixes the sense of the word Spirit (I), applies it to God and, with singular propriety, to the hypostatical energy in God (II), and offers a description of the Holy Spirit rather than a definition (III). Thesis IV then divides the description into four heads to be proved: that He is subsistent and a Person; that He proceeds from the Father and the Son and is the Third in order; that He is distinct from both; and that He is infinite, eternal, immeasurable and of the same Divinity. V and VI prove the first head from the attributes of a Person in the First Act (essence, life, understanding, will, power) and in the Second Act (creating, preserving, instructing, being grieved and blasphemed), and VII adds the passages that number the Spirit in one series with the Father and the Son. VIII takes the second head in its three members (procession from the Father, procession from the Son, third place in order and not in time or degree); IX takes the third, the distinction of Person; X takes the fourth (infinity, eternity, immensity); and XI concludes that the Holy Ghost is of one Divinity with the Father and the Son. XII calls the doctrine a mystery in its internal union and a sweetness in its economy of salvation, and closes with the apostolic benediction. Two quotations, from Basil and from Gregory Nazianzen, are printed after it.
