-1683. And although such
journeys by water and land seem to offer little good opportunity for
composition, beyond the keeping of a good journal, yet I began with a
good will, and by God's grace pursued and happily finished it....
After returning home and revising and correcting it, it was thought
advisable to submit it for further revision to the Juffrouw N.N.,[24]
which was done, and after two years I received it back with
corrections," copied it again, kept it still longer, but then in view
of the publication of Hendrick Ghysen's version (1690) found it
useless to publish. In the next winter, however, he put it into its
present form, for his own use and that of any who might be edified by
it. The preface is dated at Wieuwerd, January 8, 1691, and signed
Jasper Danckaerts.

With Sluiter we are perhaps somewhat less concerned, but he was a more
important figure in the Labadist church. We have seen (Note A) that he
came originally from Wesel, was born in 1645, and was studying
theology at Leyden in 1666. With his brother Hendrik, who was also
educated in theology and had preached at Wesel, he had joined the sect
at Herford. His sister Elizabeth had already joined them at Amsterdam.
The brother withdrew, the sister remained, and figures in Yvon's
hagiology, having died at Altona in 1674, _aet._ 23.[25] Hendrik and
Peter were "speaking brothers" in the church. Some editions of the
Declaration issued at Herford[26] bear on the title-page, along with
the names of Labadie, Yvon, and Dulignon as pastors, those of Hendrik
and Peter Sluyter as preachers. Paul Hackenberg found him one of the
chief disputants at the time of his visit.[27]

It seems almost certain that it was Sluyter of whom William Penn
speaks, in his account of his visit to Wieuwerd in 1677, when he had
conferences with the Labadists marked on his part by appreciation of
the affinity between them and the Friends. "With these two," he says,
meaning Anna Maria van Schurman and one of the three ladies van
Sommelsdyk, to whom the estate of Wieuwerd had belonged, "we had the
Company of the Two Pastors [Yvon and Dulignon] and a Doctor of
Physick.... After him the Doctor of Physick, tha
