The arrival of Dr. Thomas in this country, for the third time, A.D. 1869, led to the publication of a pamphlet, corrective of his misrepresentations, then publicly made and entitled, "A Glance at the History and Mystery of Thomasism." Its re-publication having been frequently called for, during the several years it has been out of print, its general contents, with additions, will be found in these pages. THE term Christadelphian, like the faith of those who adopt it, was constructed by John Thomas, M.D. Consequently, before the latter part of his life none was ever called by that name. It was appropriate that he abandoned the old name Christian, which had been honoured by the apostles and borne by saints and martyrs along the centuries. By inventing another name, which neither prophet nor apostle ever heard, he left the God-honoured designation for those entitled to it. It was late in his life that he originated this new name. Before that his followers were generally known as Thomasites; and properly so, because, though not accepted by them, thus was expressed their relation to him, as no one ever embraced his doctrines who did not, either directly or indirectly, obtain them from him. Accordingly, his tombstone is inscribed—"He demonstrated the unscriptural character of popular Christianity, and made manifest the long lost faith of the apostles, and at his death left behind him, as a result of his labours, a body of people in different parts of the world, known as Christadelphians." He died in March, 1871.
