Just a quick note. It’s hard to find The Everlasting Gospel by Paul Siegvolck — pseudonym of George Klein-Nicolai — even though it’s continued mentioned in Universalist history, particularly for its value in converting then-Baptist Elhanan Winchester to faith in the universal restoration.
Copies of a 1840s reprint hide at Google Books, anthologized in the Select Theological Library, published for a later generation of Universalists. Unfortunately, it was printed cheaply as a serial with very thin margins. Between this version (start at page 77) and this one (start at page 135, though the numbering restarts, so about half way through or page 438 if you download the PDF; better quality) you should be able to make it out.
