This unity must become visible so that the world may believe that separation, enmity, and hatred between people is sin.
— from the Belhar Confession
“I ask not only on behalf of these, but also on behalf of those who will believe in me through their word, 21 that they may all be one. As you, Father, are in me and I am in you, may they also be one in us, so that the world may believe that you have sent me.
— John 17:20-21 (NRSV)
