In terms of religious responsibility, Grandison, is unwilling to change his faith, and Clementina initially refuses to marry him over his religion. Grandison attempts to convince her to reconsider by claiming that "her faith would not be at risk". Besides his dedication to his own religion, and his unwillingness to prevent Clementina from being dedicated to her own, he says that he is bound to helping the Porretta family. Although potentially controversial to the 18th century British public, Grandison and Clementina compromise by agreeing that their sons would be raised as Protestants and their daughters raised as Catholics. In addition to the religious aspects, the work gives "the portrait of how a good marriage should be created and sustained". To complement the role of marriage, "Grandison" opposes "sexual deviance" in the 18th century.
