The pontificate of Pope Francis has now surpassed that of Benedict XVI in terms of duration. And Benedict has now been a "former" pope longer than he was actually the Roman pontiff.
The latest milestone comes during the eight-day Week of Prayer for Christian Unity, the "octave" when Christians ask God to guide them in healing the divisions that keep their various separated churches and communities from realizing full communion.
It is part of the ecumenical movement, which is aimed at fostering deeper relations between the different Christian denominations. Its eventual goal is the restoration of the full, visible unity of all who believe in Jesus Christ and strive to truly be his disciples.
But the work of ecumenism is severely hampered by divisions within the various denominations themselves.
