R. Tudur Jones (1921-98) was the most prolific and important of all the church historians produced in Wales during the twentieth century. Though ordained an Independent (Congregational) minister, he spent most of his life as professor of Church History and then principal of the Bala-Bangor Theological College in Bangor. He was the author of numerous scholarly books and articles. His major, two-volume study, Faith and Crisis of a Nation (Ffydd ac Argyfwng Cenedl), is considered his chief work and was published between 1981 and 1982. It appears here in English for the first time.
