This book of Maie-Noƫlle Thabut is remarkable. It is first within the reach of everyone and written in a simple and precise style. But it opens on a rich dimension of meaning. By taking all readings Eucharistic celebrations we actually discovered consistency. We are also introduced into the context in which these texts were written, moreover the author who is very familiar with the Old and the New Testament made some interesting comparisons with other scripture passages. In short, a book to read and reread with pleasure.
