The Athanasian Creed (named for its opening words *Quicunque vult salvus esse*, 'Whosoever will be saved') is a precise, rhythmic Latin theological canticle traditionally attributed to Athanasius but composed in 5th-century southern Gaul (likely by Caesarius of Arles or Vincent of Lerins), confessing that 'we worship one God in Trinity, and Trinity in Unity, neither confounding the Persons, nor dividing the Substance'.
The Augsburg Confession was drafted by Philip Melanchthon with Martin Luther's counsel and presented by Lutheran princes and electors to Holy Roman Emperor Charles V at the Diet of Augsburg on June 25, 1530.
