YOUNGSTOWN - The Catholic Diocese of Youngstown is inviting the public to attend a noon mass on Friday to pray for peace in Ukraine.

Bishop David Bonnar will celebrate mass at St. Columba Cathedral at the same time Pope Francis is scheduled to be at St. Peter’s Basilica in Rome leading an Act of Consecration of Russia and Ukraine to the Immaculate Heart of Mary.

The Friday observance will take place on the Feast of the Annunciation, a traditional celebration marking the revelation from the angel Gabriel to Mary that she would give birth to Jesus. The holy day is observed each year exactly nine months to the day before Christmas.

The Mass will be streamed online at www.doy.org/live/.

Those unable to attend or watch the Mass are invited to join in prayer.
