Unity: The Final Objective For The Church

"...Holy Father, keep through thine own name those whom thou hast given me, that they may be one, as we are. ... 20 Neither pray I for these alone, but for them also which shall believe on me through their word; 21 That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us..." John 17:11, 20-21
