What are the damnatory clauses in the Athanasian Creed?

The Athanasian Creed contains "damnatory clauses" which are stern warnings stating that unswerving adherence to its teachings on the Trinity and the Incarnation is indispensable for salvation. These clauses have led to criticism and a reduction in the creed's use in some churches, particularly in the Anglican communion. The creed begins and ends with these warnings, emphasizing that those who do not accept every detail of its doctrine will be excluded from salvation.12
