John Henry Newman,
An Essay on the Development of Christian Doctrine
“ Athanasius, who uses the words "manhood," "flesh," "the man," "economy," where a later writer would have used "nature:" and the same is true of St. Hilary. [301:3] In like manner, the Athanasian Creed, written, as it is supposed, some twenty years before [Pg 302] the date of Eutyches, does not contain the word "nature." Much might be said on the plausibility of the defence, which Eutyches might have made for his doctrine from the history and documents of the Church before his time. ”
