 A major area of concern at the Council was the debate about the principle of religious liberty . During the Council 's third session ( September to November 1964 ) Archbishop Pericle Felici announced that Lefebvre , with two other like @-@ minded bishops , was appointed to a special four @-@ member commission charged with rewriting the draft document on the topic , but it was soon discovered that this measure did not have papal approval , and major responsibility for preparing the draft document was given to the Secretariat for Promoting Christian Unity . Instead of the draft entitled " On Religious Liberty " , Lefebvre and Cardinal Alfredo Ottaviani had supported instead a text dealing with " Relations between the Church and State , and religious tolerance . "
