“Romeo:
If I profane with my unworthiest hand
This holy shrine, the gentle fine is this:
My lips, two blushing pilgrims, ready stand
To smooth that rough touch with a tender kiss.

Juliet:
Good pilgrim, you do wrong your hand too much,
Which mannerly devotion shows in this;
For saints have hands that pilgrims' hands do touch,
And palm to palm is holy palmers' kiss.

Romeo:
Have not saints lips, and holy palmers too?

Juliet:
Ay, pilgrim, lips that they must use in prayer.

Romeo:
O, then, dear saint, let lips do what hands do;
They pray, grant thou, lest faith turn to despair.

Juliet:
Saints do not move, though grant for prayers' sake.

Romeo:
Then move not, while my prayer's effect I take.
Thus from my lips, by yours, my sin is purged.

Juliet:
Then have my lips the sin that they have took.

Romeo:
Sin from thy lips? O trespass sweetly urged!
Give me my sin again.

Juliet:
You kiss by the book.” 
― William Shakespeare
