[1913 Webster]
{Athanasian creed}, a formulary, confession, or exposition of
faith, formerly supposed to have been drawn up by
Athanasius; but this opinion is now rejected, and the
composition is ascribed by some to Hilary, bishop of Arles
(5th century). It is a summary of what was called the
orthodox faith.
