Unity among all Christians is a key concern for the Catholic Church. Ecumenism, unity or cooperation with other Christian churches, is about healing and forgiving so we can all work together as a united witness to our shared faith in Christ.
The key element of ecumenism is the "Churches Together" approach to being united in faith.
The Week of Prayer for Christian Unity is traditionally observed from the 18- 25 January – the octave of St. Peter and St. Paul.
