Reflection on the role of the Virgin Mary should be a cause for rejoicing and a source for prayer"" is the way the eminent Protestant theologian Max Thurian, Prior of the Reformed Monastery at Taize, introduces his brilliant book on Mary Mother of All Christians. This kind of a study is indeed a ""cause for rejoicing"" among Catholics and Protestants alike. Author Thurian has succeeded admirably in using common scriptural texts relating to the life of Mary to find points of agreement about the role of Mary among men of all faiths. The resulting work is truly a biblical and ecumenical study which will ""provide for the spiritual edification of the contemporary Christian."" Quotations from the writings of Luther, Calvin and Zwingli are used throughout to show that their thinking on Mary's role was in accord with the traditional Catholic teaching of what the Gospels relate about the Mother of God. This is truly one book which Protestants and Catholics can share as it leads them to a deeper awareness of Mary as Mother of their Redeemer.
