In Christian teaching the Church is often spoken of as «militant, expectant, and triumphant» — as the Church in this world of time and space, as the Church as
it awaits final fulfillment, and as the Church «in heaven.»
The purely individual need for a
fulfillment that is denied to us in this life, for an everlasting love that we
await, is certainly an important motive for believing that man was made for eternity; but only in connection with the impossibility that the injustice of history should be the
final word does the necessity for Christ's return and for new life become fully convincing.»
