Four Cardinals (Raymond Leo Burke, Carlo Caffarra, Walter Brandmüller, and Joachim Meisner) formally asked Pope Francis for clarifications, particularly on the issue of giving communion to divorced and civilly remarried Catholics.[492] They submitted five "dubia" (doubts), and requested a yes or no answer. Francis declined to answer. Strong divergences of interpretation appeared among bishops and cardinals.[493][494] Some bishops issued guidelines for their diocese insisting that divorced and civilly remarried Catholics remain ineligible for the sacraments of Reconciliation and the Eucharist unless they live in continence, while other bishops opened up the possibility of access to these sacraments.[495] Cardinal Gerhard Müller, prefect of the Congregation for the Doctrine of the Faith, maintained that Amoris Laetitia should only be interpreted in line with doctrine.
