Query: A wonderful book about Mass

This book explains the nature and essence of the Holy Sacrifice of Mass, its real meaning and significance. After its reading, nobody will ever face the Holy Mass the same way again, having understood what truly happens there: the bloodless renovation of Christ's sacrifice in favour of a sinful mankind. The reader will increase in a great scale his devotion towards Mass and will assist its celebration much more frequently with major profitableness. Highly recommend for real catholics!A final note: the author, Father Martin von Cochem, lived during the second half of the 17th century and the first quarter of the 18th century, much before the disastrous Second Vatican Council; the Mass analysed in his work is obviously the eternal Roman Rite Mass - the Tridentine Mass -, not the extravagant New Order Mass of Paul VI; the book can only be fully perceived having that factor in consideration.
