Here is what Yeshua really had to say about unification, WRT the sheep:
 Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven.
 But whosoever shall deny me before men, him will I also deny before my Father which is in heaven.
 Think not that I am come to send peace on earth: I came not to send peace, but a sword.
 For I am come to set a man at variance against his father, and the daughter against her mother, and the daughter in law against her mother in law.
 And a man's foes shall be they of his own household.
The "they" to which Yeshua refered in John 17 were the true sheep, not including the tares that presently constitute the majority of the 'church.'
No, Jesus was not for unprincipled unification. But yes, He prayed from the heart, that we should be one "as He and the Father are one." Which means, not one in moral indifference and chicanery, but one in love and truth.
I have other sheep that do not belong to this fold. I must bring them also, and they will listen to my voice. So there will be one flock, one shepherd.
Bless you. And let's pray together, editor-surveyor, for the unity which He desires.
