The many apparitions of Mary during the last 150 years tell us we are at the pinnacle of the Era of Mary. In Fatima, Mary predicted the final victory of Her Immaculate Heart. The full truth of Mary's role in God's plan for Salvation will be defined in the last Marian Dogma, in which Mary will be proclaimed as Co-Redemptrix, Mediatrix and Advocate for the People of God. This book is meant to be in support of this Dogma and to act as a layman's guide to Mary's expanding role in the Church.
