One of the main theses in this thread is the observation, akin to Fr. Feeney's observation about the erosion of EENS (and subsequently the doctrine of BOD), that an ever-increasing man-centeredness about the workings of grace and man's cooperative role in salvation, and consequent erosion of the traditional Augustinian-Thomistic doctrine, was one of the distinctives of that heresy of heresies, Modernism.
You can see the "development" here in the attached definitions of three Catholic dictionaries of the word, "predestination": the first definition from an 1896 Catholic Dictionary with an imprimatur from Cardinal Manning, the second from Attwater's Catholic Dictionary (first published in 1931), and the third from an appendix to the New American Bible called "Encyclopedic Dictionary" (2006-2007 edition).
Note the "large number of Jesuits" in parens (3) in the 1896 dictionary.
