Where is the Lack of Unity Felt Heaviest?

Briefing reporters at the Vatican, the Rev. Martin Junge, general secretary of the Lutheran World Federation, said the question of sharing the Eucharistic table — or interfaith communion — is of prime importance.

"I really hope the joint commemoration gives us a strong encouragement to be faster, to be bolder and to be more creative," said Junge, "and with a very strong focus on where people feel lack of unity the heaviest, around the table."
