Question 213: What elements are essential to a Holy Mass?
Every Holy Mass (celebration of the Eucharist) unfolds in two main parts, the Liturgy of the Word and the Liturgy of the Eucharist.
In the Liturgy of the Word, we hear readings from the Old and New Testament and also the Gospel. Besides that there is an opportunity for preaching and general intercessory prayers. In the subsequent Liturgy of the Eucharist, bread and wine are offered, consecrated, and distributed to the faithful at Communion.
