Innocent gave some dispensations as the crisis progressed. Monastic communities were allowed to celebrate Mass in private from 1209 onwards, and late in 1212 the Holy Viaticum for the dying was authorised. The rules on burials and lay access to churches appear to have been steadily circumvented, at least unofficially. Although the interdict was a burden to much of the population, it did not result in rebellion against John. By 1213, though, John was increasingly worried about the threat of French invasion. Some contemporary chroniclers suggested that in January Philip II of France had been charged with deposing John on behalf of the papacy, although it appears that Innocent merely prepared secret letters in case Innocent needed to claim the credit if Philip did successfully invade England.
