The Holy Eucharist is the source and summit of Christian Life (LG. 11). Jesus instituted the Eucharist at Last supper and asked the Apostles “Do this in memory of me” (Lk 22:19). Thus from Apostolic times, the Church has been celebrating the Holy Mass uninterruptedly (Acts 2:46).

The present form of celebrating the Holy Mass has two tables, the Table of the Word and the Table of the Bread (GIRM Chapter II. No.28).The Church officially provides the Lectionary with fixed biblical texts for proclaiming the WORD in the daily celebration of Holy Mass (GILH Chapter II, Nos.36&37).
