Orthodox Christians

Does Easter belong to Jesus Christ, or to a calendar? For Pope Francis, the answer is clear.

This Easter marks a rare occurrence for Christians as Catholic and Orthodox Churches celebrate the holy day on the same date, Sunday, April 20, for the first time in eight years.

The Nicene Creed is more than a statement of faith -- it is a powerful sign of unity among Christians, Pope Francis said as he welcomed young priests and monks from Oriental Orthodox Churches to the Vatican.
