The main aims of Heschel and the Jewish side had been to encourage the alteration of the Catholic presentation of Jewish responsibility in regards to the trial and crucifixion of Jesus Christ (what is sometimes known as Jewish deicide). And in addition to this, the Jewish side wanted a stop any efforts at converting Jews to Christianity. While Cardinal Bea was highly sympathetic, attempting to present this within a framework of Catholic doctrinal orthodoxy, which it would require to pass through the Council was proving difficult to achieve, for a number of reasons. Specifically, the Gospel of Matthew mentions the blood curse and the Gospel of John many similar themes. In addition to this, the Magisterium of the Catholic Church traditionally affirmed "Extra Ecclesiam nulla salus" and that the covenant with God, since Jesus Christ was exclusively with the Christians and that the Catholic Church is the New Israel (superseding any ancestry-based Old Covenant; rendering Jewish rites null and void). These teachings had passed down through the Gospels, many Church Fathers, Doctors of the Church and Ecumenical Councils over numerous centuries. Nevertheless, Cardinal Bea, with the blessing of Roncalli intended to press forward at the Second Session with these proposed changes. It had been decided that, after the setback of the Wardi affair, the schema, now entitled ""On the Attitude of Catholics Toward Non-Christians and Especially Toward Jews"" would be incorporated as a fourth chapter under a document ""On Ecumenism""; this was satificatory to its proposers because the drafting of that document also fell under Bea's Secretariat.
