Final answer:
The correct term for the belief that oral or written discourse is guided by the Holy Spirit is 'inspiration'.
Step-by-step explanation:
The term that refers to the idea that oral or written discourse is in some way prompted and directed by the Holy Spirit is inspiration. This belief holds that the messages of religious texts or prophetic speeches are not solely of human origin but are inspired by the deity or an intermediary such as the Holy Spirit. In some religious traditions, it is considered that certain texts or messages were dictated by the deity, meaning they came directly from a divine source. In contrast, writings that believers think were written by the deity suggest an even stronger level of divine authorship, as if the deity itself held the pen.
