Edward Elwall, born 9 November 1676, died 29 November 1744, was a mercer and grocer, born at Sedgley near Wolverhampton. He was a Unitarian and a Sabbatarian Baptist; that is, his day of rest and worship was the seventh day, the biblical Sabbath, rather than the first day of the week, the “papal pagan Sunday,” as he called it, which is kept by orthodox Christians. The people of Wolverhampton referred to him as ‘Jew Elwall,’ because of his Sabbath-keeping. He is said to have occasionally attended the Mill Yard Seventh Day Baptist Church in London. In 1727 Elwall published his Unitarian beliefs in A true testimony for God and his sacred Law; being a plain, honest defence of the First Commandment of God, against all the Trinitarians under Heaven: ‘Thou shalt have no other gods but me.’ Source: Wikipedia (en)
