Catholics are divided on issues such as divorce and birth control amid widespread resentment at Church teachings, two surveys have found.
The Vatican sent out questionnaires to parishes worldwide in November, before a synod this October.
Results from several countries have now been released, showing that, in Switzerland, 90 per cent of respondents called on the Church to give communion to divorcees who remarry. In Germany, bishops said the survey showed Catholics viewed the communion ban as "unjustified discrimination and ... merciless".
German respondents also rejected bans on premarital and gay sex and birth control.
The decision to carry out the survey reflects Pope Francis' promise to listen to Catholics' concerns, but there are fears that such openness could open a Pandora's box of dissent.
