Modern scholarship on Late Antique philosophy seems to be more interested than ever before in examining in depth convergences and divergences between Platonism and Early Christian thought. Plotinus is a key gure in such an examination. is paper proposes a pre- liminary study of the Plotinian concept of aptitude, as it emerges throughout the Enneads and aims at shedding light to certain aspects of Plotinian metaphysics that bring Plotinus into dia- logue with the thought of Church fathers by means either (...) of similarities or di erences between Neoplatonist and Christian thought. It will be argued that the concept of aptitude is crucial as it involves the relation between the One and the many, the reality of participation, the relation of the cosmos with, and its dependence on, the superior spheres of being, the bestowal of divine gi s upon beings, and the possibility of the dei cation of the human being.
