St. Louis de Montfort's classic Total Consecration to Mary has seen a strong resurgence in recent years, with Catholics around the world consecrating themselves to Our Lady. Building off this momentum, we wanted to encourage this closeness to Jesus through Mary, but with a preparation that reflected the Church's love for St. Thomas Aquinas. In Aquinas's writings, we found ample resources for the task. Especially in his preaching, we discovered passages detailing the graces bestowed on Mary and the role afforded her in leading us to Christ. Special inspiration came from a passage where Aquinas describes what motivates religious to consecrate themselves. He writes that it is their great desire to "e;offer to God all that one has."e; Wow! That struck a chord. We wrote this book to assist others in offering all that they have in consecration, with the Angelic Doctor as a teacher and guide. After all, it's not just religious who are called to holiness. We all are! It is our hope that this method will captivate you like it has us, and lead you to closer union with Jesus as you offer yourselves to Him through Mary.
