According to a source the u.s. invited jews to join the born again christian movement some time ago. According to a report, the modern ecumenical movement began with the anglican and lutheran churches between the world wars.
Reportedly, the ultimate goal of ecumenism is a full communion of the protestant, catholic and orthodox churches, but there are different opinions on what Christian unity should be and how it should be achieved. Seen to be political, a possible sign of jewish ecumenism are rabbis in the media with european features and political bias.
