In response, Leo IX wrote the letter "In terra pax" of 2 September 1053, addressed to Cerularius and Leo of Ohrid, in which he speaks at length of the privileges granted through Saint Peter to the see of Rome. In one of the 41 sections of his letter he also speaks of privileges granted by the emperors, quoting from the "Donation of Constantine" document, which he believed to be genuine (section 20). Some scholars say that this letter was never actually dispatched, but was set aside and that the papal reply actually sent was the softer but still harsh letter "Scripta tuae" of January 1054.
