Why the author compare virgin Mary and Jesus and Hester Prynne and her child?

The comparison between Mary and Jesus and Hester Prynne and her daughter Pearl in the Scarlet letter is somewhat limited.

Pearl, like Jesus. is a somewhat uncomfortable character for the society around her, pointing out truths that they would like to ignore. Pearl draws attention tothe less than good and godly aspects of Puritan society.
