Dear HP,
This says nothing about Christ NOT WANTING us to be united.
According to the metaphor in John ch 10 those that COME OUT of the sheep pens ARE united for that is the flock.. Those in the sheep pens are merely clubbers or religionists..
The flock was/is/ and always been united.. various sheep pens are just "holding pens".. for those needing to hear his voice.. I know, I know that doesnt leave a lot of room for clergy.. But Oh! Well..
