The author critically presents the concept of God's substantiality, given by Fonseca and Suarez, showing its historical context. The issue of God's substantiality discussed by Jesuits comes down to the statement that God is an individual, substantial and concrete entity, yet they posed some objections to that opinion and gave extra explanations. All in all, such conclusions are close to nominalists. Although the Jesuits verbally opposed nominalism, they remained under its influence. It proves that nominalism - in spite of being completely discredited - was still appreciated.
