Cap. II Sol. Arg. 2: Vulgate "conformes fieri" — not election from foresight of works
Second: Paul did not write "whom he foreknew would be conformed, he predestined," but "whom he foreknew" (that is, foreloved) "he predestined to become conformed" — as the Vulgate rightly supplies what the Greek leaves open. So God is not said to predestine from foresight of our works, but to foreknow the good works he prepared for those already predestined.
Latin
Secundo, non dixit Apostolus, quos praescivit futuros conformes praedestinavit; sed, quos praescivit (hoc est, predilexit) praedestinavit conformes fieri, ut vulgata versio recte supplevit, quod in Graeco contextu deest. Non itaque Deus praedestinare dicitur ex praescientia operum nostrorum, sed praescire bona nostra opera quae praedestinatis praeparavit.
