The Cathedral Basilica of SS. Peter and Paul hosted an ecumenical prayer service Jan. 20 to commemorate the Week of Prayer for Christian Unity celebrated this week throughout the world in the Catholic Church. Clergy and faithful from several Philadelphia church communities and the Cathedral Parish met in the Cathedral’s chapel to sing hymns, reflect on Scripture readings, pray and express their commitment to unity in Christ and solidarity with one another in the Gospel.
