It is sometimes said that even if no rules were laid down for the conduct of its affairs, the Church, being created by Jesus to "further the work of the Kingdom of God," can be judged by the extent to which it is successful in continuing his work. This supposition rests upon a misunderstanding of what is meant by "the Kingdom of God"… The Kingdom itself is not something to be "furthered" or "built" by men's efforts.
It is something which we are invited to recognize as already present, after a manner, in the life and work of Jesus. It is something to be inherited or entered into by those who believe. The task of the Church, in other words, is not to set the stage for a better world than this one but to draw the curtain from it, to reveal something that is already there.
