Occasion. The fifth 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 Peter de la Fite. It is one of the seven also printed in the Syntagma, where it stands as Disputation V and is dated 23 February 1605.
The doctrinal move. The disputation takes the First and Second Persons of the Trinity in turn. Theses I–VI treat the Father: I fixes the sense of the name (the relation to the only-begotten Son, not adoption or creation) and gives a description of the First Person; II shows that he may be called a Person, by five properties; III that he is a Person in the Holy Trinity, that is, God, against those who deny the Father's Deity; IV that he is placed first, in order and not in time, as fountain and origin of the Divinity; V that he begets by communicating his nature, which answers the charge of a Quaternity; VI that the begetting is from all eternity. Theses VII–XIII treat the Son: VII states that he is the Second Person, begotten and not created or adopted; VIII that he is a Person on the same five properties; IX announces four classes of argument for his Deity, and X–XIII give them in turn (the names he bears, the attributes ascribed to him, his works, and Old Testament passages about Jehovah applied to him in the New). XIV sets out the order of the Second Person, who lives, understands and works from the Father; XV argues from Micah v, from the Son's eternity and from the Word that he is eternally begotten; and XVI gives the agreement (one nature, homoousios) and the distinction (the mode of subsistence) between Father and Son, and ends in a prayer for the communion of the Spirit.
