Religious issues and discourse are key to an understanding of Shakespeare's plays and poems. This dictionary discusses over 1000 words and names in Shakespeare's works that have a religious connotation. Its unique word-by-word approach allows equal consideration of the full nuance of each of these words, from 'abbess' to 'zeal'. It also gradually reveals the persistence, the variety, and the sophistication of Shakespeare's religious usage.

Frequent attention is given to the prominence of Reformation controversy in these words, and to Shakespeare's often ingenious and playful metaphoric usage of them. Theological commonplaces assume a major place in the dictionary, as do overt references to biblical figures, biblical stories and biblical place-names; biblical allusions; church figures and saints.
