 On models that take faith of the theist kind to consist fundamentally in an act of trust, the analogy with interpersonal trust is suggestive. When one person trusts another there seems typically (though not uniformly) to be a doxastic aspect (the truster’s belief that the trustee is trustworthy). But what’s essential is the fiducial aspect, which consists in an active commitment or ‘entrusting’ to the other. Paul Helm proposes that theist faith similarly has importantly distinct doxastic and fiducial aspects: in addition to belief about God’s existence and trustworthiness for salvation held with a degree of strength proportional to the believer’s evidence, persons of faith must also entrust themselves to the one on whom they rely (Helm 2000). While it is widely agreed that theist faith must have a cognitive aspect, some philosophers hold that this need not be doxastic (as we shall see in Section 8).
