Many thanks for your quotation. I was not aware of this intended
publication. Where can I find the exact text of the original German
manuscript in a more recent edition (Meiner, Suhrkamp)?

I take it that you are talking about Hegel's Manuscript On the
existence of God, not about the 2nd edition of the Phenomenology
(on this later one, Hegel had only begun some few pages from teh
introduction until he died), right?

I am sure that you have access the 20 volume Hegel suhrkamp edition,
which is (due to its cheap price and the available CD-ROM versions)
the easiest available Hegel edition in German today. In that edition,
volume 17 (e.g. stw 617) contains this manuscript (in a version
edited by Marheinken) on page 345ff under the Title "Vorlesungen über
die
Beweise vom Dasein Gottes"). When you have a look at the notes of the
editiors concerning that text, at page 538-539, you will see that the
lecture, which seem to have been the base of that manuscript, was held
in 1829 as an additon to Hegel's courses on Logic. It also mentions,
that the original manuscript, according to that note nearly finished
("fast vollständig ausgearbeitet"), has been lost, so that Lasson, who
did the next edition of that work works in 1930 needed to use the
previous
work of Marheinke instead of the Manuscript.

As these remarks from teh editors are pmost probably from teh first
edition
of teh suhrkamp works of 1969, it is possible -while not very likely-
that
the original manuscript has been found in the mean time. You could try
to ask
Walter Jaeschke at the Bochumer Hegel Archiv, if you like.

HTH and all the best,
Kai
