litourgía
Litourgía is a Greek word derived from "leitos" (public) and "ergon" (work). Historically, it referred to a public service or duty undertaken by a citizen for the benefit of the state, often involving financial contributions or the provision of services. In ancient Greece, this could range from equipping a warship to funding a religious festival. The concept emphasized civic responsibility and the obligation of individuals to contribute to the common good.
In a religious context, particularly within Eastern Christianity, litourgía has evolved to mean a public act
