There is so very little which I can usefully add to the excellent review here by the Reverend Father Condon, so let me say ditto.
You may discover this same excellent explication of our vows in a later edition by the Pauline Sisters Bombay Society (2001) at ISBN-10: 8171764479 under Poverty, Celibacy and Obedience ; A Radical Option for Life but we are grateful for this present economical edition from the great spiritual printing house Crossroad, as this theological treatise by a well published member of the Sacred Heart Missionary Congregation truly opens up to us the infinite depths of the meaning and the message and the mystery and the mission and the significance of our traditional vows of poverty, chastity and obedience, founded upon the firm and brave and gentle ground of non-violence.
Once we begin to understand underlying principles we can understand applications. Thus once we understand the underlying chords and scales in music we may begin to improvise and to live correctly yet freely. Once we understand our calling to Christ through Saint Augustine's famous epigram above, we live in Love and in freedom and in dignity, as the most recent Papal promulgations compel us. Once we understand the underlying principles of our religious vows, we find in them not restrictions but freedom and love and joy.
Often when we stay with the exteriors, we establish house rules, we find limitations, we find death of the life of Love. When we reflect upon the principles we find the freedom of God, who is Love. When we dwell upon the exteriors we invent ways around them and thus violate the principles while convincing ourselves that we observe the vow. Thus Jesus commands us to Love our enemies, yet we wind up centuries later pleasing the Empire by inventing a contorted and unholy "just war" theory which violates the principles of Jesus. As O'Murchu reminds us here "In fact, the principle was so widely abused that St. Thomas Aquinas in the Thirteenth Century affirmed that war is always sinful, even if it is occasionally waged for a just cause (p. 7)."
Thus we find religious communities whose individuals take vows of poverty yet which communally own great properties and excuse their limousines as property of the community, while violating the underlying principles, poor friars enjoying a wealthy house. Thus we discover the profound and criminal scandal of the Vatican Bank.
O'Murchu here calls us back to the foundational principles through a renewed and most ancient perspective. We have all heard of the underlying virtues of Faith, Hope and Charity as walking hand in hand with uour vows. Here we find a fresh and close and profound examination of the vows in the most traditional light of non-violence.
O'Murchu opens with an analysis of the principle of non-violence throughout the history of the Church, complementing this presentation with an examination of other tradition's principle of non-violence, including Gandhi's ahimsa and satyagraha, and their application as agape by the Reverend Doctor Martin Luther, Jr.
In fact, O'Murchu compellingly exhorts us that the vows are not only designed for individual salvation in the after-life, but build in fact the Kingdom of God here and now, compelled, as the recent Apostolic Exhortation by His Holiness Pope Benedict XVI Sacramentum Caritatis: el Sacramento de la Caridad: una Exhortacion Apostolica Postsinodal reminds us, by the Eucharist in ipse.
O'Murchu thereby brings us a fresh and profound means of contemplating our religious vows and their integral application in our lives. Having defined non-violence admirably, O'Murchu applies it to each of the vows, showing how each vow is a demonstration of commitment to nonviolence, in areas of economics, sexuality and in humble submission to God's Holy Will, rejecting earthly powers and dominations for the Kingdom which comes, which we make real within our Holy Vows.
Highly recommended for all Catholic religious and indeed for all practicing Catholics seeking to live our Faith in a materialist and individualist and aggressively greedy and sensualist land. Please see as well the other writings by this great spiritual thinker including Consecrated Religious Life: The Changing Paradigms.
