In the mid-18th century, the Church of Scotland faced some considerable upheaval. The
Church’s General Assembly, despite opposition from a great number of its congregations,
ratified a significant shift in the Church’s policies for electing and placing ministers. As a
result, some of the dissenting congregations chose to secede from the Church of Scotland,
forming the United Secession Church in 1733. A decade later, John Willison, as well as
merely documenting the event, wrote A Fair and Impartial Testimony as a call for
the dissenting congregations to make peace and return to the Church of Scotland.
