And now I am no more in the world, but they are in the world, and I am coming to thee. Holy Father, keep them in thy name, which thou hast given me, that they may be one, even as we are one.
The oneness of the Church is a Tinitarian, not a monolithic, oneness. It consists, not in being assimilated by the Borg and made a parrot for a completely uniform life of exactly the same tastes, opinions, thoughts and feelings, but of becoming part of a community of fully human persons all sharing in the life of the Community of Persons that is the Blessed Trinity, who is One. Hear O Israel, the Lord our God, the Lord is One. The Church, which is the Body of the Lord Christ is to be one in the same way.
