The work of our redemption is continued, and its fruits are imparted to us during the celebration of the liturgy.I haven't persevered in reading the book from cover to cover, but have dipped into a few of its chapters from time to time. What is interesting about the book, particularly my 1969 edition, is what it reveals about the assumptions about liturgy and what one might call "liturgical theology" as they are presented by one of the foremost liturgists of the time. Many of those assumptions would now be seen as very "traditional", and it is interesting to be reminded that they were the ordinary content of the Liturgical conversation at that time. There are chapters that present a sound understanding of grace and of the Church as the Mystical Body of Christ in which we come to share in the Divine life. The first chapter strongly affirms the necessity of worship of God as part of the human vocation. The chapter that includes an account of the Sacrament of Anointing of the Sick also includes an explanation of the plenary indulgence offered to the faithful at the time of death when the receive the Apostolic Blessing from the priest (how many Catholics even know about that nowadays? My observation about it is that, between the Sacrament of Anointing and the Apostolic Blessing, even the most nominal of practising Catholics would have to be rather negligent to end up in purgatory).
A second point of note is that there are very able - by which I mean both doctrinally sound and catechetically effective - explanations of many of the key theological ideas involved. Many a contemporary catechist could look to this book as a source of ideas about how to present liturgical ideas in a parish context.
One might have a different view of the history of the Liturgical movement than that presented by Fr Howell (I have still to read those chapters properly). But nevertheless, as a witness to "where things were at" during the times of the Second Vatican Council itself, I think this is a very useful book.
