AUGUSTINE. (con. Serm. Arian. c. 7. [9.]) If men are disturbed however by its being said that the Word was made flesh, without mention of a soul; let them know that the flesh is put for the whole man, the part for the whole, by a figure of speech; as in the Psalms, Unto thee shall all flesh come; (Ps. 65:2) and again in Romans, By the deeds of the law there shall no flesh be justified. (Rom. 3:20) In the same sense it is said here that the Word was made flesh; meaning that the Word was made man.
John 1:14 and the Word was made flesh, and dwelt among us.
St Augustine is calling this a synecdoche.
