For by means of the creation itself, the Word reveals God the Creator; and by means of the world [does He declare] the Lord the Maker of the world; and by means of the formation [of man] the Artificer who formed him; and by the Son that Father who begat the Son: and these things do indeed address all men in the same manner, but all do not in the same way believe them.
Irenaeus of Lyons
Against Heresies, Book IV
Chapter VI
