Which polyphonic style of liturgical vocal music is based on a biblical or other religious prose text?

The polyphonic style of liturgical vocal music based on a biblical or other religious prose text is known as "motet". Motets are polyphonic compositions that set a sacred text to music, typically in Latin, and often involve the use of multiple voice parts. Motets can be traced back to the 13th century and were widely composed during the Renaissance and Baroque eras. They were commonly performed during religious services and were often used for special occasions or feasts. Motets can vary in complexity, with some featuring elaborate contrapuntal textures and others being more straightforward in their musical structure.
