Recently I was at a conference where a Roman Catholic presenter gave an excellent review of post-modernism and its effects on our society. At the end of it he put up these words from John 17: 20-21:
“I do not pray for these alone, but also for those who will believe in Me through their word; that they all may be one, as You, Father, are in Me, and I in You; that they also may be one in Us, that the world may believe that You sent Me.”
