There have been about five different schisms from the Church of Scotland over the past 120 years.
The Free Presbyterian Church of Scotland and the Free Church Scotland Continuing are the two traditionally Calvinist Presbyterian churches in Scotland.
There are about 5 million people in Scotland. About 2.25 million identify themselves as Church of Scotland/Presbyterian but only 500,000 people are officially members of the Church of Scotland. About 25,000 of those declaring themselves Presbyterians are traditional Calvinists.
There are 750,000 Roman Catholics in Scotland, of whom about 150,000 attend Mass regularly, and about 25,000 Anglicans.
Almost 2 million Scots say they have no religion.
There are 40,000 Muslims in Scotland.
God in His Infinite Wisdom is allowing the heresy of Calvinism to Darwin itself (!!!) out of existence. As in many things (including Communism), the United States of America is the last holdout remnant of odious and oppressive beliefs.
