Venema:
1) It is usually asked what kind of knowledge that is by which God knows things that are conditionally future. The Jesuits here introduce their scientia media, to which they assign a middle place between scientia simplicis intelligentice and scientia visionis; inasmuch as God by the former knows things merely possible–things not absolutely but only conditionally future.
Here, therefore, scientia media is required. But we say in reply, that this scientia media is introduced without reason and foundation, because nothing else is necessary to the knowledge of future contingent events than the knowledge of the connexion between the antecedent and the consequent. Now the connexion between the conditions, namely, and the occurrence of events, is either necessary or arbitrary and free, and depending on the decree of God. If it be necessary it belongs to scientia simplicis intelligentice, by which God knows things with their consequences and relations. Thus he knew that the inhabitants of Keilah would deliver up David; not, however, by scientia media, but by scientia simplicis intelligentice, by which he knows the relations of things, whether these relations be absolutely or restrictedly necessary. But if the connexion be arbitrary, or depend upon the free determination of the will of God, then it belongs to scientia visionis, or to that knowledge by which he knows by his decree the relations and issues of things. Now there is a general decree by which he has ordained the connexions of things. This knowledge, therefore, belonged to that part of the decree by which he instituted the mutual relation of events, such as that which we have already adverted to in the case of Joash who, if he had smitten the arrows upon the ground five or six times, would have smitten and consumed Syria. The event in this case depended on the good pleasure of God, because he had instituted the connexion between it and what went before.
Such also is the connection between the condition of salvation and salvation itself;–”H e that believeth shall be saved”–a connexion which depends upon the free decree of God. The same remarks may be applied to all conditionally future events. Hermann Venema, Institutes of Theology, trans., by Alex W. Brown, (Andover: W.F. Draper Brothers, 1853), 155.
