Cap. IV Arg. 6: perpetual use of Electi — in salvation contexts always means believers
Arg. 6. Another argument from the standing use of Elect wherever salvation is in view — Rom. 8: Who will accuse God's elect?; Rom. 11: The elect have obtained; Matt. 22: Many called, few elect. From these and like places: the word Elect, when Scripture speaks of salvation, is always used for believers; therefore there is no election to salvation except of believers.
Latin
Arg. 6. Petitur aliud argumentum a perpetuo usu vocis, Electi, quotiescunque ponitur cum respectu ad salutem; ut Rom. viii. Quis accusabit adversus electos Dei? et Rom. xi. Electi assecuti sunt, et Matth. xxii. Multi vocati, pauci electi. Ex hisce aliisque locis consimilibus ita argumentantur; Vox Electorum, cum de salute agitur, perpetuo in Scripturis usurpatur pro credentibus: Ergo nulla est electio ad salutem nisi credentium.
