The initial conflict was regarding just what model of religious freedom was to be put before the council, with the traditionalists calling for religious tolerance but claiming that an abstract right to religious liberty was relativistic. Before the council both the Pontifical Council for Promoting Christian Unity led by Cardinal Augustin Bea and the Theological Commission (led by Cardinal Alfredo Ottaviani) introduced revised drafts of statements to the Central Commission. Pope John XXIII in July appointed an ad hoc joint committee to resolve differences and Bea's "Unity" submitted a revised draft. Negotiations between the various commissions broke down after this point.
