Term used to designate one of the theological systems which purpose to reconcile grace with free will.
It was first scientifically developed by Luis de Molina, a Spanish Jesuit, and was, in all its essentials, adopted by the Society of Jesus.
It seeks the ultimate solution of the difficulty in the free created will, but precisely as prepared and assisted by Divine grace.
For the infallibility of the connection of grace with the consent of the free will, it falls back upon God's foreknowledge through the scientia media, a mediate (not an immediate) knowledge.
