Describe symbolism in Restoration by Rose Tremain

In Part I, Chapter XIII, one cannot ignore the religious symbolism present in the exchange between the King and Merivel. Merivel has commited the one sin he is forbidden, falling in love with his wife. This is an allusion to Eden and the tree of the knowledge of good and evil. Adam and Eve, too, commit the one act forbidden them. The King (God) cannot forgive Merivel, and thus, Merivel is banished from his Eden..... his mansion at Bidnold, and cast into the cruel world of futility to work for his bread with the sweat of his brow, or his scalpel, like the rest of humanity.
