A "Dogmatic Constitution" is a formal document that outlines essential beliefs and doctrines of a religious organization, particularly within the context of the Catholic Church. These constitutions serve to clarify and define core tenets of faith, guiding the beliefs and practices of its followers. One of the most notable examples is the Second Vatican Council's Dogmatic Constitution on the Church, known as Lumen Gentium. This document emphasizes the nature of the Church, its mission, and the role of the laity, aiming to foster a deeper understanding of the Church's purpose in the modern world.
