At a time when many Catholics are convinced that they require more spiritual direction in their own lives, Father Jette's book can fulfill a definite need. The message in the Spiritual Teaching of Mary of the Incarnation seems as pertinent to men of the twentieth century as it must have to men of the seventeenth. The author synthesizes the spiritual doctrine of the Venerable Marie Guyart, the Ursuline Nun who -- as the first missionary woman of modern times -- is often referred to as the ""Teresa of Avila of the New World"". Her correspondence from Quebec to friends in France was voluminous, but Father Jette through it to find the most salient features of her teachings on how to embark upon the spiritual life and how to make progress in it. She contended that ""the most life consists in being a perpetual holocaust to the Glory of God by the practice of the maxims of the Gospels and by familiarity with the inner life of Jesus"". Mental prayer she found ""an island of peace in our daily lives"". Married moderns can take comfort in the many times she stressed the primacy of the duties of one's state in the life saying ""If God has put us amid the troubles of this world's business, we shall sanctify ourselves there and nowhere else. He is usually found there more completely and more purely than in actual solitude"". Her twelve maxims of daily life echo the and could provide an excellent source for many meditations. Too bad if the , unappealing title keeps anyone from delving into this book. Mary of the incarnation's teaching offers spiritual riches to all.
