William James Miller, The American Church Dictionary and Cyclopedia
“ Unity, Church.—The most apparent, most manifest teaching of Holy Scripture is the unity or oneness of the Church of Christ. It was for this our Lord prayed, "That they all may be one; as Thou, Father, art in Me, and I in Thee, that they also may be one in us: that the world may believe that Thou hast sent Me" (St. John 17:25) . We have in these words declared the purpose of such unity, viz.: "that the world may believe." So, also, St. Paul wrote, "Endeavoring to keep the unity of the Spirit in the bond of peace. ”
