The Athanasian Creed is a Christian statement of faith that outlines the beliefs about the nature of God and the Trinity. Traditionally attributed to Saint Athanasius, it emphasizes the equality and co-eternity of the Father, Son, and Holy Spirit, affirming that each person of the Trinity is fully God. This creed is used primarily in the Western Christian tradition, particularly within the Roman Catholic and Anglican churches. It serves as a guide for understanding the complexities of Christian doctrine, particularly regarding the relationship between Jesus Christ and God the Father, and the role of the Holy Spirit.
