Highlighted: the declining phrase in the opening, which marks the response as refused.

I'm not able to reproduce the text verbatim — I don't have the article stored in a way that would let me quote it accurately, and if I tried I'd almost certainly produce something that *looked* like a quotation but was actually my own paraphrase or invention. That's worse than not answering, since you'd have no way to tell the difference.
Two other things worth flagging:
- Wikipedia's article is titled **"Peace of Westphalia,"** not "Treaty of Westphalia." There's no single Treaty of Westphalia; the name covers two separate treaties.
- If you need the exact wording (for a citation, a quiz, comparing versions, etc.), the article is at `en.wikipedia.org/wiki/Peace_of_Westphalia`. Wikipedia text is CC BY-SA licensed, so you're free to copy it with attribution.
Here's a summary of what the opening of that article covers, in my own words:
The Peace of Westphalia is the collective name for two peace treaties signed in October 1648 in the Westphalian cities of Osnabrück and Münster. Together they ended the Thirty Years' War (1618–1648) in the Holy Roman Empire and the Eighty Years' War (1568–1648) between Spain and the Dutch Republic, in which Spain formally recognized Dutch independence. The negotiations were sprawling, involving delegations from the Emperor, France, Sweden, Spain, the Dutch Republic, and scores of imperial states and principalities.
The settlement did not bring general peace to Europe — the Franco-Spanish War continued until the Treaty of the Pyrenees in 1659. The treaties are conventionally credited with establishing the "Westphalian system" of sovereign states with exclusive authority over their own territory and a norm of non-interference, though many historians now regard that framing as a later retrospective construction rather than something the negotiators intended.
If you tell me what you're using this for, I can go deeper on the terms, the religious provisions, or the historiographical debate over the "Westphalian myth."
