Catholic Church Dogmas are the core beliefs and doctrines that are considered essential to the faith of the Catholic Church, which have been formally defined by the Church's magisterium. These dogmas serve as foundational truths for Catholic theology and practice, shaping the beliefs of millions of adherents worldwide. Throughout the 20th and 21st centuries, these dogmas have been both challenged and reaffirmed, reflecting continuity and change within the Church in response to modern issues and societal changes.
