Restored to its primitive glory

Before I can accede to your pretensions I must see, not
only that the Church was such in the beginning, but, moreover,
that it is according to God's will that it be restored to its
primitive glory; and, furthermore, that a voluntary union of
"two or three" or two or three and twenty, or several such
bodies, are each of them entitled, in any locality, to take the
name of the Church of God, when that Church originally was an
assemblage of all believers in any given locality.

And let me here dwell on a most important consideration, which they who are
bent on making churches have overlooked. They have had their
thoughts so fully engaged in their churches that they have
almost lost sight of the Church. According to Scripture, the
whole sum of the churches here on earth compose the Church, at
least the Church on earth; and the Church in any given place
was no other than the regular association together of whatever
formed part of the entire body of the Church, that is to say,
of the complete body of Christ here on earth; and he who was
not a member of the Church in the place in which he dwelt, was
no member of Christ's Church at all.
... John Nelson Darby (1800-1882)
