Believe in God and Have Faith? On Assent, Trust, and the Preposition That Faith Turns On

This essay asks whether believing in God and having faith are the same act. Drawing on the classical distinction among credere Deum, credere Deo, and credere in Deum, it argues that faith cannot be reduced to increasingly firm assent that God exists. Reason may reach Deus est—that there is a Non-Derivative Ground on which created actuality depends—but the structure of dependence yields a That, not the Who. Who the Ground is, whether He has spoken, and what He asks cannot be deduced from metaphysical grounding but must, if known, be disclosed by revelation. Faith therefore begins not where reason fails, but where the revealing God is received as First Truth and the person is moved toward Him as end. Within the Gaitan Topology, revelation does not abolish the epistemic Wall: the creature cannot seize the divine interior, but the One beyond the Wall may freely disclose Himself. The essay further argues that faith is neither weak knowledge nor assent on insufficient evidence. It is a supernatural and free act: an infused habit, inwardly moved by grace, and genuinely elicited by the believer. Faith thus recovers, in the register of the will, the preposition metaphysical error loses: not merely that the creature is in God, but that, by grace, it freely goes toward Him.
