Of justification four disputations clearing and amicably defending the truth against the unnecessary oppositions…

Yet (as I said before) when we intend to express, not only or principally the Act of the Receiver, but also, or principally, the Grace of the Giver, then it is a fitter phrase to say, we are Justified by faith in his Blood, or by Receiving Christ the Saviour and Justifier: because it fulliest and fitliest expresseth that Grace which we intend, (and thus Paul oft doth.) So that they who distinguish between Fides quae Justificat, and Fides qua Justificat and admit that Act into the former, which they exclude from the latter, must prove what they say. (Fides qua justificat, non Recipit Christum vel ut Regem vel sacerdotem, sed tantum Justificat. i. e. Qua est Conditio, non est Receptio: Nec qua Recipit Justificat; i. e. Qua Receptio, non est Conditio: Materia & forma non sunt confundenda. Actus fidei est quasi materia, vel Aptitudo tantum ad officium conditionalitatis: Distinctio igitur ipsa est inepta.) Now to your Answers: (Pardon this prolixity.)

First I must tell you, that by that phrase [the whole soul] I mean the entire motion of the soul by Understanding and Willing, ⟨p. 360⟩to its Object both as True and Good: For I know the whole soul may be said to understand in every Intellectual Action, and to will in every act of willing. But when it only understands or Assents, and not willeth, it doth not Act fully according to its Power, nor according to the nature of its Object, when the Goodness is neglected, and the Truth only apprehended. And it is not a complete motion, seeing the Acts of the understanding are but introductory or preparatory to those of the Will, where the motion of the Rational soul is complete. And so my Argument stands thus: If Justifying faith be the Act both of the understanding and the Will, then it is not one single act only: But &c. Ergo, &c. Prob. Anteced. Justifying faith is the Receiving of Christ: but Christ is Received by the Understanding and Will; (by the former incompletely, by the latter completely:) therefore Justifying faith is the Acting both of the Understanding and Will. Probatur Minor. Christ must be Received as Good, and not only his Word (or himself) as true: therefore he must be Received by the Will as well as the Understanding: for Goodness is the object of the Will.
