Vatican City, May 12, 2015 / 12:02 am (CNA/EWTN News).- In a message sent Sunday to the leader of the Coptic Orthodox Church, Pope Francis said advances toward reconciliation are strengthened by the martyrs and that Christians must unite to confront shared global challenges.

“Today more than ever we are united by the ecumenism of blood, which further encourages us on the path towards peace and reconciliation,” Pope Francis wrote May 10 to Pope Tawadros II of Alexandria.
