1093In the sacramental economy the Holy Spirit fulfills what was prefigured in the Old Covenant. Since Christ's Church was "prepared in marvellous fashion in the history of the people of Israel and in the Old Covenant" (Lumen Gentium 2) the Church's liturgy has retained certain elements of the worship of the Old Covenant as integral and irreplaceable, adopting them as her own: -- notably, reading the Old Testament;
-- praying the Psalms;
-- above all, recalling the saving events and significant realities which have found their fulfillment in the mystery of Christ (promise and covenant, Exodus and Passover, kingdom and temple, exile and return).
Yes, the readings usually follow the plan: Old Testament, Psalm, New Testament (Epistle or other non-Gospel reading), Alleluia verse, Gospel in a Sunday Mass. The Second reading is omitted during the week, and the first reading may be from either the Old Testament or the New Testament.
The first reading is usually from the Old Testament or from the Acts of the Apostles during the Easter Season.
The Bible is used in Mass during the Liturgy of the Word. An Old Testament reading, some psalms, a New Testament reading and a Gospel reading all come from the Bible at this point of the mass. At other points in the mass there are references that come from the Bible, like at the consecration and some prayers.
During a Sunday service or a Sunday mass, any reading can be taken from the books in the bible, from the book of Genesis to the book of revelation.And usually the sermon is based on these readings.
In a Catholic mass, the Old Testament may be read by a lector or a priest. The New Testament reading, if it isn't a Gospel, may be read by a lector or priest. The Gospel is read by a priest.
This question can be understood in terms of reading only the Old Testament but not the New Testament, or in terms of reading only the Old Testament but nothing else that could contradict or challenge the stories and traditions portrayed in the Old Testament. For a Jew, there is no particular disadvantage in reading the Old Testament but not the New Testament, as the New Testament is not relevant to his religion. For a Christian, the disadvantage is that the books most important to his faith are in the New Testament. Anyone reading only the Old Testament and not what is now known about the history of the times and biblical scholarship on the Old Testament, the disadvantage is that the reader must take everything literally and can not have an informed view as to how literally the Old Testament should be read.
The Second Reading generally comes from one of the books in the New Testament, not including the Gospels. Usually it comes from an epistle, or a letter, written to the early Christians by St. Paul. This is because the epistles make up the good majority of the New Testament.
It is always from the New Testament. The first reading is usually ( but not always) from the Old Testament (Hebrew Scriptures)
.Catholic AnswerThe first two readings during a Sunday Mass are usually from the Old Testament and the New Testament - Epistles or Revelation. The last reading is always the Gospel taken from St. Matthew, St. Mark, St. Luke, or St. John's Gospel.
Usually the Old Testament.
Old Testament
The first reading in Catholic and many Protestant churches is traditionally chosen from the Old Testament to tell of God's promises and his preparation of his people for the coming of the Messiah (his Son).The Old Testament reading harmonizes with the Gospel reading and reveals the continuity between Israel and Jesus who comes not to replace,but to fulfill the scripture.
