 He argues that in the Fathers and the great scholastics there was only one concrete order of history, that in which God had made humanity for himself, and in which human nature had thus been created only for a single destiny, which was supernatural.Neither the Fathers nor the scholastics, therefore, ever envisioned the possibility of a purely natural end for human persons attainable by their own intrinsic powers of cognition and volition.De Lubac argues that this unified vision began to unravel in the thought of theologians such as Denys the Carthusian and, more pertinently, Cajetan.
