Week of Prayer for Christian Unity
The Week of Prayer for Christian Unity is celebrated around the world January 18-25, though the week may be observed to include two Sundays. The theme for this year is, Do you believe this? (John 11-26) in recognition that 2025 marks the 1700th anniversary of the first Christian Ecumenical Council held in Nicea, Constantinople. Christians express their personal “I believe” in praying the Nicene Creed and seeking a deeper understanding of ecumenism by meeting, celebrating liturgy and praying our oneness in Christ with Christians of other denominations.
