Introduction To Christianity - pg. 182

From the standpoint of Christian faith one may
say that for history God stands at the end,
while for being he stands at the beginning.
This indicates Christianity's all-embracing horizon,
which distinguishes it both from mere metaphysics
and from the future-oriented ideology of Marxism.
Since Abraham and until the return of the Lord, faith
advances to meet him who is coming. But in Christ the
countenance of him who is to come is already revealed:
it will be the man who can embrace all men because he
as lost himself and them to God. For this reason the
emblem of him who is to come must be the cross, and
his face in this era of the world must be a countenance
of blood and wounds: the "last man", that is, the real ,
the future man reveals himself in this age in the
last men; whoever wishes to stand on his side
must therefore stand on theirside.
