The quality of mercy is not strained.
It droppeth as the gentle rain from heaven
Upon the place beneath. . . .
. . .
It is enthronèd in the hearts of kings;
It is an attribute to God himself,
And earthly power doth then show likest God’s
When mercy seasons justice. Therefore, Jew,
Though justice be thy plea, consider this:
That in the course of justice none of us
Should see salvation. We do pray for mercy,
And that same prayer doth teach us all to render
The deeds of mercy.
(IV.i.179197)

Even as she follows the standard procedure of asking Shylock for mercy, Portia reveals her skills by appealing to his methodical mind. Her argument draws on a careful process of reasoning rather than emotion. She states first that the gift of forgiving the bond would benefit Shylock, and second, that it would elevate Shylock to a godlike status. Lastly, Portia warns Shylock that his quest for justice without mercy may result in his own damnation. Although well-measured and well-reasoned, Portia’s speech nonetheless casts mercy as a polarizing issue between Judaism and Christianity. Her frequent references to the divine are appeals to a clearly Christian God, and mercy emerges as a marker of Christianity. Although it seems as if Portia is offering an appeal, in retrospect her speech becomes an ultimatum, a final chance for Shylock to save himself before Portia crushes his legal arguments.
