What is the significance of vomiting by the monster error?

Okay I actually had to look this up. I totally forgot about the vomit.

When Redcross strangles Errour she spews vomit full of books and papers with “loathly frogs and toades, which eyes did lacke” (1.1.20.6-7). These books and papers are the various pamphlets from the pamphlet wars of Spenser’s time period. These pamphlets were designed to persuade Christians towards each groups’ own religious ideals and ended up dividing the once unified church into a number of different groups. Spenser’s description of these books and papers as vomit is a real sign of his own personal belief in a unified church.
