to the pope the most complete and highest power, however in a manner where the fullness and primacy are in harmony with the rights of the patriarchal sees. This is why, in virtue of an ancient right founded on customs, the Roman Pontiffs did not, except in very significant cases, exercise over these sees the ordinary and immediate jurisdiction that we are asked now to define without any exception. This definition would completely destroy the constitution of the entire Greek church. That is why my conscience as a pastor refuses to accept this constitution. Patriarch Gregory refused to sign the Council's dogmatic declaration on papal infallibility. He and the seven other Melkite bishops present voted non placet at the general congregation and left Rome prior to the adoption of the dogmatic constitution Pastor Aeternus on papal infallibility. Other members of the anti-infallibilist minority, both from the Latin church and from other Eastern Catholic churches, also left the city. After the First Vatican Council concluded an emissary of the Roman Curia was dispatched to secure the signatures of the patriarch and the Melkite delegation. Patriarch Gregory and the Melkite bishops subscribed to it, but with the qualifying clause as used at the Council of Florence attached: "except the rights and privileges of Eastern patriarchs.". He earned the enmity of Pius IX for this. According to one account, during his next visit to the pontiff, Gregory was cast to the floor at Pius' feet by the papal guard while the pope placed his foot on the patriarch's head. This story, however, has been cast into doubt by more recent studies of the First Vatican Council. John R. Quinn cites Joseph Hajjar in his book Revered and Reviled: A Re-Examination of Vatican Council 1,: "We have been unable to find any document to provide historical verification for such treatment by the Pope." Orthodox historian A. Edward Siecienski reports that the historicity of this story "is now deeply suspect." Despite this, Patriarch Gregory and the Melkite Church remained committed to their union with the Church of Rome. Relationships with the Vatican improved following the death of Pius IX and the subsequent election of Leo XIII as pontiff. Leo's encyclical Orientalium dignitas addressed some of the Eastern Catholic Churches' concerns on latinization and the centralizing tendencies of Rome. Leo also confirmed that the limitations placed on the Armenian Catholic patriarch by Pius IX's 1867 letter
