Six bishops, three of them cardinals, have signed a statement reaffirming the Church’s teachings on marriage and morality.

The Declaration of Fidelity to the Church’s Unchangeable Teaching on Marriage and to Her Uninterrupted Discipline has gathered more than 4,000 signatures worldwide since its launch last week.

The signatories say they are resolved “to remain faithful to the Church’s unchangeable teachings on morals and on the Sacraments of Marriage, Reconciliation and the Eucharist, and to Her timeless and enduring discipline regarding those sacraments.”
