"A Christian statement of belief focused on Trinitarian doctrine and Christology. [. . .] The creed has been used by Christian churches since the sixth century. It is the first creed in which the equality of the three persons of the Trinity is explicitly stated. [. . .]
"A medieval account credited Athanasius of Alexandria, the famous defender of Nicene theology, as the author of the Creed. According to this account, Athanasius composed it during his exile in Rome and presented it to Pope Julius I as a witness to his orthodoxy. This traditional attribution of the Creed to Athanasius was first called into question in 1642 by Dutch Protestant theologian G.J. Voss, and it has since been widely accepted by modern scholars that the creed was not authored by Athanasius, that it was not originally called a creed at all, nor was Athanasius' name originally attached to it."
