● Ecumenism refers to the movement towards religious unity amongst Christian denominations.
● Unity does not mean uniformity. The aim is not to combine all denominations but to acknowledge that their unity in Christ outweighs their diversity in practice and beliefs.
● Ecumenism began when individuals recognised that what Christians have in common is more significant than the things that divide them.
● In the past, there has been significant conflict between the Christian denominations and ecumenism is allowing the denominations to work, worship and dialogue together.
● Being divided does not allow Christians to be effective witnesses of Christ’s message of love to the world. For the world to believe in the message of Jesus Christ, his followers should be united
● Ecumenism is the opposite of sectarianism (which is division and conflict within a religion) and allows the sharing of resources and cooperation.
● Catholics are united with other Christians through faith and Baptism; they cannot ignore the relationship they have with other Christians
● The Second Vatican Council issued the Decree on Ecumenism (The Restoration of Unity); the Catholic Church committed itself to work with other Christian Churches and communities to bring full unity in Christ
● Catholics believe that the one Church of Jesus Christ which existed in the beginning continues to exist in their own Catholic Church and recognise that many of the same essential elements of the Church are present to different degrees in other Churches
● From the beginning of the ecumenical movement, prayer for unity has been one of its most fundamental characteristics.
There are various levels of ecumenical developments:
At the highest level, there are joint commissions: formal ecumenical bodies which work to find official agreement on issues which have often divided denominations. E.g. The Anglican Roman Catholic International Commission (ARCIC) has held discussions on topics such as Baptism and Mary.
Next, on a practical level, there are many Christian denominations that come together on social justice issues and during times of crisis. Examples of this 'action based' ecumenical response could be seen in the Bushfires earlier this year (Read newspaper article below) as well as the annual Palm Sunday Peace March.
At a local parish level ‐ grass roots initiatives have been undertaken to implement ecumenism throughout the community. Examples are inter‐denominational prayer services.
Lastly, on an educational level there are initiatives such as the Sydney College of Divinity which is part of an ecumenical federation on theology and ministry.

'Nostra Aetate ' - Vatican II’s Declaration on the Relation of the Church to Non-Christian Religions.
Interfaith relations and the Catholic Church
2025 marked the 60th anniversary of Nostra Aetate (“in our time”), Vatican II’s Declaration on the Relation of the Church to Non-Christian Religions. This document transformed the Church’s attitude towards believers from other religions. For the first time in history, the Church spoke positively about other religions. The Declaration is widely considered a “watershed” in the relations between Catholics and believers from other religions. It continues to inspire and to guide Catholics in forging relationships of mutual respect and collaboration.
The 60th anniversary of Nostra Aetate provided Catholics with the opportunity to consider the multi-religious reality of Australia and the world “in our time”, and assess what members of the Catholic Church are doing to build relations with believers from other religions.
Each Catholic will build relations with believers from other religions in his or her own way.
The Catholic Church provides the following suggestions:
• Meet and greet your neighbours and work colleagues from other religions; offer congratulations for a wedding or a birth, offer condolences on a death; a smile can make a world of difference.
• Learn about the faiths of others from a reliable source; the best way to break down stereotypes is to meet with one of the faithful, so that their religion is not just an idea, but has a face and a name.
• Be curious; ask questions; do not be invasive, but a sincere, respectful enquiry will almost always allay fears, elicit a genuine response and lead to better mutual understanding.
• Visit the place of worship of another religion to experience their sacred space; some mosques and temples have guides who explain the beliefs and practices of the religion.
• Invite a representative from another religion to address your class, school, congregation, church or social group.
• Hospitality is a biblical and cultural virtue; extend an invitation for a cup of tea or a meal, showing sensitivity by observing appropriate dietary restrictions; be open to receive hospitality; sharing an iftar meal to break the fast at the end of the day during Ramadan is a great way to build relations with Muslims.
• Work together on matters of common social concern, justice and peace issues, education, child-care, social services, aid to those in need and care for the environment.
• Offer greetings on major feast days, such as Deepavali (Hindu), Eid al-Fitr (Muslim), Pesach (Jewish) and Vesach (Buddhist).
• Attend celebrations of major feast days as a gesture of solidarity and interest.
• Learn about and practice The Golden Rule, “In everything do to others as you would have them do to you” (Mt: 7:12)
• Pray for believers from other religions; on special occasions such as feast days, include them in the prayers of the faithful.
• Take part in multi-religious events for various occasions, celebrating national days, praying for peace, showing shared religious solidarity in the face of natural and other disasters.
