The Calvinist modus operandi is to start with a priory (preconceived ideas) on the attributes of God and then interpret the text of the Bible in light of those concepts. Augustine actually admits to this in his Confessions (chapter 12). But John Cassian (360–435AD) actually provides a very good example of this kind of thinking in his Institutes. Cassian claims that because we understand God’s eternal nature, that the proclamations of God in the Bible must be taken metaphorically:

And so as without horrible profanity these things cannot be understood literally of Him who is declared by the authority of Holy Scripture to be invisible, ineffable, incomprehensible, inestimable, simple, and uncompounded, so neither can the passion of anger and wrath be attributed to that unchangeable nature without fearful blasphemy. For we ought to see that the limbs signify the divine powers and boundless operations of God, which can only be represented to us by the familiar expression of limbs: by the mouth we should understand that His utterances are meant, which are of His mercy continually poured into the secret senses of the soul, or which He spoke among our fathers and the prophets: by the eyes we can understand the boundless character of His sight with which He sees and looks through all things, and so nothing is hidden from Him of what is done or can be done by us, or even thought. By the expression hands, we understand His providence and work, by which He is the creator and author of all things; the arms are the emblems of His might and government, with which He upholds, rules and controls all things. And not to speak of other things, what else does the hoary hair of His head signify but the eternity and perpetuity of Deity, through which He is without any beginning, and before all times, and excels all creatures? So then also when we read of the anger or fury of the Lord, we should take it not ἀνθρωποπαθῶς ; i.e., according to an unworthy meaning of human passion, but in a sense worthy of God, who is free from all passion; so that by this we should understand that He is the judge and avenger of all the unjust things which are done in this world
