Ms. Davis and her husband, Joe, were sneaked into the Vatican Embassy by car on Thursday afternoon, according to Ms. Davis’s lawyer, Mathew D. Staver. The couple met for about 15 minutes with the pope, who was accompanied by security, aides and photographers. Mr. Staver said he expected to receive photographs of the meeting from the Vatican soon.

On Wednesday, a Vatican spokesman, the Rev. Federico Lombardi, confirmed the meeting, but declined to elaborate on it. He said he “did not deny that the meeting took place, but I have no other comments to add.”
