backslide

Backslide is a term with multiple meanings, primarily referring to a regression or relapse into a previous, less desirable state. In a religious context, it describes a believer returning to sin or abandoning their faith. This can involve a loss of spiritual commitment, a return to old habits, or a complete rejection of religious doctrines. The concept of backsliding is often discussed in theological discussions about free will, grace, and the possibility of losing salvation.

Beyond religious connotations, "backslide" can be used more generally to describe a decline in performance, progress, or adherence to a standard. For example, a company might backslide in its market share after a period of growth, or an individual might backslide in their fitness goals after a period of dedication. This usage implies a movement away from a positive trajectory towards a less favorable one. The term can also refer to the act of slipping backward physically, especially on a slippery surface, though this is a less common usage. The core idea across these meanings is a reversal of progress or a return to a former, less advanced or more problematic condition.
