Which Christian teachings are explained in the two main sections of the Athanasian Creed?

The Athanasian Creed, also known as the Quicumque vult, is divided into two main sections. The first section expounds on the Christian doctrine of the Trinity, explaining the unity of God as Father, Son, and Holy Spirit, and their distinct yet co-equal divine nature. The second section focuses on the Incarnation, detailing the nature of Jesus Christ as both fully God and fully human. The creed begins and ends with strong warnings that adherence to these doctrines is essential for salvation. It was likely composed in southern France around the 5th century and is attributed to the teachings of the 4th-century Church Father Athanasius, though he was not its author. The creed's strong condemnatory clauses have led to its restricted use in some churches.12
