divine invocation

Divine invocation is a formal appeal to a god, deity, or sacred power, typically at the beginning of a ceremony, speech, or creative work.

The practice appears in religious rituals, legislative sessions, and classical poetry, where invoking divine presence or guidance lends solemnity and authority: The meeting opened with a divine invocation.

In literary tradition, poets invoke the muse as a form of divine invocation, asking for inspiration to tell their story.
