John Calvin (1509-1564) was the exegete par excellence amongst the early Protestant divines, even though in the nineteenth and twentieth centuries he has been better known for his theological institutes. Calvin’s commentating was philologically and historically oriented, like some of his predecessors, and like those of a more Antiochian orientation, he had real issues with allegorizing of the Biblical text. Perhaps here is a good point to make some distinctions.
There is a difference between a straight allegory (see e.g. Bunyan’s Pilgrim’s Progress), which has its referents and real meaning entirely outside the narrative or story it tells, and a narrative that has some allegorical or symbolic elements, again where the meaning of those elements is outside the story itself, and finally the allegorizing of non-allegorical texts, or the over-allegorizing of texts that are not full-blown allegories. Mostly what the church fathers of an Antiochian bent were complaining about was those last two approaches—allegorizing a non-allegorical text or over-allegorizing a text with only some symbolic elements in it, like a parable.
A summary of Calvin’s exegetical principles included his concern for clarity and brevity, the determining of the intention of the author, the establishing of the historical, geographical and institutional background, and the analyzing of the literal grammatical meaning of a text within its literary context. Calvin was also concerned to find Christ in the OT, but this raised the spectre of allegorizing.
