I had a chance to study Catholic Liturgy at the turn of the new year, 2023. Our teacher assigned us to read Romano Guardini's book, The Spirit of the Liturgy. He asked us to summarize a couple of its chapters. I found it hard to understand. Fortunately, there are summaries of the chapters available online. Notable among these are the ones of Adoremus Bulletin which are listed below:
Chapter 1 The Prayer of the Liturgy
Chapter 2 The Fellowship of the Liturgy
Chapter 3 The Style of the Liturgy
Chapter 4 The Symbolism of the Liturgy
Chapter 5 The Playfulness of the Liturgy
Chapter 6 The Seriousness of the Liturgy
Chapter 7 The Primacy of the Logos over the Ethos
