Benedict XVI celebrated Vespers on January 25 to mark both the Feast of the Conversion of St. Paul and the end of the Week of Prayer for Christian Unity. The liturgy, which was attended by representatives of various Christian denominations, took place at the Basilica of St. Paul Outside-the-Walls. The video of his homily is above, while, past the break, you can listen to the introduction to the liturgy by Cardinal Kurt Koch, the President of the Pontifical Council for Promoting Christian Unity.
