Martyr: one grace, passive at first, then active and passive
Thesis XXI. Peter Martyr likewise, at the place mentioned several times, says that operating grace is the grace that heals and changes our will at the start, and cooperating grace is the grace that makes the will, once changed and healed, act rightly. He adds that operating and cooperating grace are one grace, not two.
He explains that the two names arise because the will, when it is first healed, concurs with grace passively. For, he says, it is said to be changed, and we are said to be regenerated. Afterwards it is both active and passive, because, moved by God, it too wills and chooses.
Latin
XXI. Sic etiam Petrus Martyr loco saepius memorato dicit gratiam operantem esse quae ab initio voluntatem nostram sanat & immutat: cooperantem vero quae efficit ut ea immutata & sanata recte agat. Quibus addit gratiam operantem & cooperantem esse unam gratiam non duas. Hujus autem variae denominationis rationem esse docet, quod voluntas quum primum sanatur concurrit cum gratia passive. Nam, inquit, ea immutari dicitur, & nos dicimur regenerari. Postea vero active & passive se habet. Nam a Deo impulsa ipsa quoque vult & eligit.
