On Sunday in the Basilica of St. Mary Major, there was a performance of the Synodal Choir of the Patriarchate of Moscow together with the Sistine Chapel Choir.
Pope Francis sent a message for the event, which was read by Cardinal Leonardo Sandri, prefect of the Congregation for Eastern Churches.
Here is a translation of the message:
