Testard: sufficient grace as universal, efficacious as particular
Thesis XXXVI. Apart from the Remonstrants, some of the Reformed who subscribe to the Synod of Dort also divide grace into sufficient and efficacious, though in a quite different sense. Paulus Testardus, pastor of the church at Blois in his lifetime, uses this distinction in his Irenicum, thesis 300, and in many places in his book on nature and grace.
By sufficient grace, however, he means what he calls universal grace, and by efficacious grace what he names particular grace.
Latin
XXXVI. Praeter Remonstrantes autem, ex Reformatis qui subscribunt Synodo Dordracenae nonnulli quoque gratiam distinguunt in sufficientem atque efficacem, sensu tamen non parum diverso. Quippe hac distinctione utitur Paulus Testardus, dum viveret Pastor Ecclesiae Blaesensis, in Irenico thesi trecentesima, & in libro de Natura & Gratia pluribus in locis. Sed per gratiam sufficientem intelligit illam ipsam quam universalem vocat, per gratiam autem efficacem, eam quam nominat particularem.
