DIALOGUE IS THE KEY

BE A BRIDGE BETWEEN PEOPLE IN AN AGE OF DIVISION

In our increasingly polarized world, it’s up to people of faith to heal the rifts among us. This starts with a genuine dialogue between members of different religions and between different traditions and perspectives within each religion.

Graymoor Ecumenical & Interreligious Institute (GEII) has long been recognized as a leader in the research and practice of ecumenism and interreligious dialogue. Whatever your tradition, we welcome you and invite you to explore our many resources and events.

TESTIMONIALS

Ecumenical Trends, aptly named, is an essential resource for anyone interested in current developments in ecumenical and interfaith relations. The articles dig deep and go broad, a gift to readers in any context.

Ecumenical Trends has a long history of serving the journey towards Christian unity by providing readers with scholarly but accessible coverage of ecumenical developments, and creating a space for those engaged in the ecumenical enterprise to express ideas or raise questions which help move the dialogue forward. It is a vital resource in the Spirit-led walk towards reconciliation among Christians and dialogue between faiths and all seeking the common good.
