Pedro Arrupe, S.J., who served as Superior General of the Society of Jesus from 1965 until 1983, frequently refers to the Sacred Heart of Jesus in his personal letters and writings. These writings become something of a collection of love letters, letters of a love that is unique but not exclusive, a love that is total and at the same time concrete, a love that is quotidian and defining, which led Fr. Arrupe to give his entire life to Jesus Christ without reservations. Jesuit Sources, housed at the Boston College Institute for Advanced Jesuit Studies, has released a new edition of In Him Alone is Our Hope: Texts on the Heart of Christ, principal texts by Fr. Arrupe on the Heart of Christ. This new edition features an introduction by Arrupe biographer Pedro Miguel Lamet.
