Commission decided to include in the schema references to previous papal rejections of contraception, but not to issue any condemnation of its own. The Pope was satisfied with this solution. Nevertheless, when time came for final approval, the opposition stayed firm: 11% of the Council Fathers still rejected the schema. In the midst of all this voting, there was another public session on November 18, and two of the remaining schemas became the Dogmatic Constitution on Divine Revelation Dei verbum and the decree on the Apostolate of the Laity Apostolicam actuositatem. Indulgences One of the issues some bishops wanted discussed at the council was that of indulgences, but the topic never made it onto the conciliar agenda. A month after his being elected pope in the summer of 1963, Paul VI set up a commission to study the issue. The commission produced a report suggesting a mild modernization of the practice of indulgences, but no important changes. Once it became clear that the workload of the fourth period would be less than originally expected, the Pope decided to use some of the available time to ask the national groups of bishops for their reaction to the report. November 10 and succeeding days were set aside for responses. Eleven national groups delivered oral responses in the Council hall, and 12 others written responses. The Italian and Spanish bishops were favourable to the report, while most others were highly critical: they cast doubt on the theological foundation of indulgences, and suggested a complete reform of the system, some even urging outright abolition. Patriarch Maximos IV insisted there was no evidence of indulgences during the first millennium. The presentations were cut short after 2 days. Two years later, Pope Paul would decree a modest reform of the system of indulgences, while insisting on their importance. The Council's Final Days On December 4, Pope Paul took part in an ecumenical prayer service with the hundred or so non-Catholic observers present at the Council in the Basilica of Saint Paul outside the Walls. It was the first time a Pope had prayed publicly with non-Catholic Christians, something unthinkable just a few years earlier. On December 6, there were speeches at St. Peter's thanking everyone who had taken part in the council. Each Council Father received a gold ring to commemorate the historic event. The Pope declared a jubilee from 8 December to Pentecost 1966 (later
