Cap. IV Arg. 3 Sol: beneplacitum that includes praedestinatio is the arcane will from the mass
The good pleasure that actually includes predestination is not those declared statutes, but God's eternal secret will: from the same mass of perdition he resolved with himself to lead some persons infallibly to glory by pure mercy through efficacious grace, and according to justice to leave others in the perdition they merit.
Latin
Beneplacitum ergo illud in quo ipsa praedestinatio includitur, est aeterna illa et arcana Dei voluntas, qua statuit apud se, ex eadem perditionis massa quasdam personas ex pura misericordia per gratiam efficacem ad gloriam infallibiliter perducere, aliis secundum justitiam in merita perditione relictis.
