 Under Pope Paul II, the Venetian Pietro Barbo (1464–1471), Carvajal was appointed along with Cardinal Bessarion and Cardinal d'Estouteville to a commission to consider the state of ecclesiastical affairs in Bohemia.The underlying issue was the orthodoxy and reliability of the Utraquist King of Bohemia, George of Poděbrady.Carvajal deeply distrusted him, and believed "that it would be absolutely necessary to employ the knife in the case of wounds which admitted of no other remedy, and to guard against fatal corruption by severing the decayed members from the body of Holy Church."
