第二章：逾越奥秘的圣事庆典
Chapter Two: The Sacramental Celebration of the Paschal Mystery
1135礼仪的教理讲授首先需要理解圣事的经纶（第一章）。在此光照下，其庆典的革新得以彰显。因此，本章将论述教会圣事的庆典。它将探讨在不同礼仪传统的多样性中，七件圣事的庆典所共有的内容。每件圣事特有的内容将在后面分别论述。这一关于圣事庆典的基本教理讲授回应了信徒对此主题提出的首要问题：
1135The catechesis of the liturgy entails first of all an understanding of the sacramental economy (Chapter One). In this light, the innovation of its celebration is revealed. This chapter will therefore treat of the celebration of the sacraments of the Church. It will consider that which, through the diversity of liturgical traditions, is common to the celebration of the seven sacraments. What is proper to each will be treated later. This fundamental catechesis on the sacramental celebrations responds to the first questions posed by the faithful regarding this subject:
– 谁在庆祝礼仪？
– Who celebrates the liturgy?
– 礼仪如何庆祝？
– How is the liturgy celebrated?
– 礼仪何时庆祝？
– When is the liturgy celebrated?
– 礼仪在何处庆祝？
– Where is the liturgy celebrated?
