Cap. III Sol. Rat. 9 close: can destine glory depending on others' sins without prior foresight to confer
So the argument's assumption was false — that glory which somehow depends on others' sins cannot be decreed except from such foresight. It can be decreed or destined without that; it is only the conferring that cannot happen unless foresight of that sort goes first.
Latin
Falsum ergo fuit quod in argumento assumptum erat, nempe, non posse eam gloriam, quae aliquo modo dependet ex peccatis aliorum, decerni nisi ex tali praescientia. Decerni enim vel destinari potest, quamvis non conferri, nisi hujusmodi praescientia praeeunte.
