The Letters of Bishop Basil of Caesarea: Instruments of Communion. By Fr. Silouan Fotineas. Early Christian Studies 19. Macquarie Park: Sydney College of Divinity Press, 2018. xi + 382 pp

In setting out the impetus for this investigation, Fr. Silouan writes: "The letters of Basil remain largely unutilised with respect to their contribution to ecclesiology. . . . In response to this neglect, this book will attempt, first to bring to the surface the contents of these letters and their notion of ecclesial communion, and second, to show how for Basil the very act of letter-writing was itself an instrument of communion. . . . The argument will show how Basil used his letters to facilitate communion in the Nicene church." (7–8, 9).
