For example:

“Divorced and remarried, unmarried couples living together, are certainly not models of unions in harmony with Catholic doctrine, but the Church cannot look the other way. For which reason the sacraments of reconciliation and of communion ought to be given also to so-called wounded families and to those who even though living in situations not in line with the traditional canons on matrimony, express a sincere desire to draw closer to the sacraments after an adequate period of discernment.” 

We now have Cardinal Muller, Prefect of the Congregation for the Doctrine of the Faith, who said: Communion for the remarried is against God’s law and cannot be changed, being contradicted by the Cardinal Coccopalmeria, President of the Pontifical Council, responsible for issuing binding interpretations of the Code of Canon Law.
