Can faith be defined as a specific degree of belief, that is a fluid position along a continuum, rather than a binary, "on/of" state? This paper aims to provide an overview of the current scholarship on this question, developing distinctions necessary to understand the issue and exploring the implications for the nature of faith and the relationship between faith and faithlessness. The central discussion of my paper will focus on the distinction between Bayesian and non-Bayesian credences. In Bayesian epistemology and psychology, credences are often associated with objective probability. I will argue that in the context of faith, credence, defiined as the psychological strength of a belief, must be distinguished from the objective probability of that belief, and may even be conceived as inversely correlated to it. Finally, I will discuss the consequences of such a distinction.
