I am not sure what you mean by double speak, but let's try this:
Juliet: The more I give to thee, the more I have. This line is said when she professes her love for Romeo on the balcony; in other words, "It is in giving that we receive." Such paradox offers deep meaning when it is filled with emotion.
Romeo: "Call me but love, and I'll be new baptized." - He is saying that he will take a new name because that is what baptism symbolizes in his world. That is when a child's name is given so he is saying that her love will make him an entirely new person.
