Many folk (in my experience) are under pressure as to what they can or cannot do on the Sabbath.
For example , you gave a reference to "The Sabbath Question" by MacGregor and in part 4 he deals with "Sabbath Rail trafic" and the DUTY of Christians. What relevance has this today in 2004 when we all (or should IMHO), think nothing of driving a car , taking a bus , a taxi or even a train to church on Sunday ?
What IS THE SABBATH in 2004 AD ? I am a gentile saved by the free and sovereign grace of The Lord Jesus Christ. Who decides what THE SABBATH is ? The WCF ? <img src="/forum/images/graemlins/shrug.gif" alt="" />.........
