Pope Francis has said Christian Churches must unite against barbarism of the Ukrainian war after meeting participants in the Plenary Assembly of the Pontifical Council for Promoting Christian Unity.
He also referred to other parts of the world where wars have broken out, saying they must challenge the conscience of every Christian and every Church.
The meeting took place from May 2-6, the theme was called "Towards an ecumenical celebration of the 1700th anniversary of Nicaea."
Within the meeting Pope Francis said: "We must ask ourselves: what have the Churches done and what can they do to contribute to the development of a world community, capable of creating fraternity starting from peoples and nations who live social friendship?
He added "Ignoring the divisions among Christians, out of habit or resignation, means tolerating the pollution of our hearts that makes the ground fertile for conflict."
"The proclamation of the Gospel of peace, that before the armies disarms the hearts, will only be more credible if announced by Christians finally reconciled in Jesus, Prince of Peace.
"Christians that are animated by His message of universal love and brotherhood, which goes beyond the boundaries of their own community and nation."
