January 18-25, 2019 is the annual observance of the Week of Prayer for Christian Unity. The theme for 2019 is “Justice, and only justice, you shall pursue” (Deuter- onomy 16:18-20) and was prepared by churches in Indonesia. In a world marked by diversity in language and culture, we express our Christian faith in diverse ways. During this week we are called to celebrate this diversity and be faithful to Christ’s call for the unity of his Church. All are invited to join with brothers and sisters in prayer, song, and witness to unity as followers of Christ.
