Originally published in 1945, this book was formed from the content of the Thirlwall Prize essay for 1941. The text presents a comprehensive study of Reginald Pecock, the fifteenth-century Bishop of Chichester whose trial for heresy and public abjuration to save himself from burning are the best remembered events in his life. Pecock's writings are used extensively in discussion of his character and scholarship, theological standing, attitude to the Lollards and significance in the religious life of his time. This book will be of value to anyone with an interest in Pecock, the history of Christianity and British history.
