Grammar checking the U.S. Constitution

I just wrote out the Constitutional phrase "he shall take care that the laws be faithfully executed" in an outline, and Microsoft Word thinks I should change "be" to "are."

There's no joke here. Only sadness.

UPDATE: I added in this:

Art. II § 2 cl. 2: “He shall nominate, and by and with the Advice and Consent of the Senate, shall appoint Ambassadors, other public Ministers and Consuls, Judges of the Supreme Court, and all other Officers of the United States, whose Appointments are not herein otherwise provided for, and which shall be established by Law: but the Congress may by Law vest the Appointment of such inferior Officers, as they think proper in the President alone, in the Courts of Law, or in the Heads of Departments.”

and it tells me that the sentence is too long. Why amend the Constitution when you can just let Microsoft spell and grammar check it?
