Catholic Teaching on Ecumenism

Catholic Teaching on Ecumenism by Rev. Allan R. Laubenthal is a clear, accessible guide to the Catholic Church’s official teaching on Christian unity, ecumenism, and interchurch dialogue.

With practical insights for prayer, dialogue, study, and action, the book equips Catholics to participate in Christ’s call “that all may be one” (John 17).

Ideal for adult faith formation, parish study groups, or personal enrichment, this book helps Catholics understand their faith more deeply while engaging respectfully with other Christian traditions.
