A similar surprise awaits the visitor to New England, it may be even a greater. For if he should tread In the footsteps of the Pilgrim Fathers and find the 'lineal descendants' of their original places of worship at Plymouth, Salem, or Boston, he will find _Unitarians_ in possession. So it is in many of the oldest towns founded by the American colonists of the seventeenth century. In their centres the parish churches, 'First,' 'Second,' or otherwise, stand forth challenging everybody's attention. There is no lack of self-assertion here, nothing at all like the shrinking of the Old English Presbyterian into obscure alleys and corners. Spacious, well appointed, and secure, these _Unitarian_ parish churches, in the words of a popular Unitarian poet, 'look the whole world in the face, and fear not any man.' The object of the present brief sketch is to show how these landmarks have come to be where they are, to trace the thoughts and fortunes of Unitarians from their rise in modern times, to indicate their religious temper and practical aims, and to exhibit the connections of the English-speaking Unitarians with some closely approximating groups in Europe and Asia. Before entering upon a story which is extremely varied and comprehensive, one or two important points must be emphasized. In the first place the reader must bear in mind that the term 'Unitarianism' is one of popular application. It has not been chosen and imposed as sect-name by any sect-founder, or by any authoritative assembly. There has never been a leader or a central council whose decisions on these matters have been, accepted by Unitarians as final. Even when most closely organized they have steadily resisted all attempts so to fix the meaning of 'Unitarianism' as to exclude further growth of opinion. Consequently there is always room for variety of opinion among them; and every statement of their principles and teachings must be taken as a sort of average estimated from a survey more or less extended. Thus the significance of Unitarianism as a feature of modern religious development cannot be grasped apart from its history as a movement of thought. Nowhere is it more necessary than here to reflect that to know what a thing is we must know what it has been and consider what its future naturally involves.
