A Catholic, whose interest in the movement for Christian unity urges him to make ecumenical contacts with other Christians amongst whom he lives, will find himself, at least in town and city areas, confronted by Presbyterians, by Methodists, Congregationalists and Baptists, and with a certain dominance of prestige by Anglicans. For his encounter a Catholic ecumenist will want to know about some if not all of these differing religious bodies; what sort of people are they, what divides them from each other, on what are they agreed? He will probably need knowledge to supplement his vague ideas of their history and how they came into being. He will be interested in their antecedent presuppositions, but still more in what are their aspirations, hopes, doubts and fears today concerning the prospect of future unity; its possibility, the changes it would involve and its dangers.
The Star Books on Reunion a series of six inexpensive paperbacks on unity as Anglicans, Presbyterians, Methodists, Congregationalists, Baptists and Roman Catholics see it, contains the substance of this information in accessible and readable form. It is a pity that a seventh volume, on the Eastern Orthodox, was not included in the series, for full understanding of unity problems, especially the theological ones, requires the witness of these ancient churches. The authors are well chosen, highly qualified, theologically and pastorally, to represent the position of their respective communions. All of them share common ground in their conviction of the paramount importance of the ecumenical approach between Christians.
