The theological virtue of hope has long been neglected in Christian ethics. However, as social, civic and global anxieties mount, the need to overcome despair has become urgent. This book proposes the theological virtue of hope as a promising source of rejuvenation. Theological hope sustains us from the sloth, presumption and despair that threaten amid injustice, tragedy and dying; it provides an ultimate meaning and transcendent purpose to our lives; and it rejoices and refreshes us 'on the way' with the prospect of eternal beatitude. Rather than degrading this life and world, hope ordains earthly goods to our eschatological end, forming us to pursue social justice with a resilience and vitality that transcend the cynicism and disillusionment so widespread at present. Drawing on Thomas Aquinas and virtue ethics, the book shows how the virtue of hope contributes to human happiness in this life and not just the next.
