The purpose of this book is to present the Immaculate Heart of Mary in the Trinitarian and Christological light that illumines the authentic Christian life. Many have mistakenly thought that God has given Mary only a minor role in the economy of salvation because there seem to be few biblical references to Mary. This fallacy is a tragic one. If the importance of Mary depends on many verses in Scripture explicitly dealing with her, what are we to say of the central events of the life of Jesus Christ?We are living in times when what has been secret to many is being discovered about Mary in the very pages of the inspired word of God, the Sacred Scriptures. Mary is emerging as the great woman of the Bible, as a teacher of true faith. The Mother of God is now seen more clearly as the spouse of the Holy Spirit in making Jesus, the risen Lord and Savior, present in us and among us. True devotion to Mary brings Jesus Christ, in fact, the entire Blessed Trinity, into our lives.
