For a Mass, before the Gospel reading the Deacon, Priest or Bishop sings or says:
“The Lord be with you.”
The people reply: “And with your spirit.”
The Deacon, Priest or Bishop: “A reading from the holy Gospel according to N.”
(Here for “N.” they sing or say, Matthew, Mark, Luke or John.)
At the end of the Gospel reading the Deacon, Priest or Bishop sing or say: “The Gospel of the Lord.”
All reply: “Praise to you, Lord Jesus Christ.”
The Church has other ceremonies where there may not be a Deacon, Priest or Bishop. Examples of these ceremonies are a Communion Service or a “Celebration of the Word of God”. If the Gospel is being read in these ceremonies by a lay person (a person who is not a Deacon, Priest or Bishop) then it would be incorrect for them to say “The Lord be with you.”
At Mass when there are readings from the Bible that are not Gospel readings, then for example:
“A reading from the letter of St James”
At end of the reading:
“The word of the Lord.”
All reply: “Thanks be to God.”
In other ceremonies there are readings that are not from the Bible. For example, The Office of Readings, Advent, Week 2, Tuesday has as the second reading:
“A reading from the Constitution on the Church of the Second Vatican Council”.
The first reading is “A reading from the prophet Isaiah”.
Neither reading ends with “The word of the Lord.”
In the Book of Blessings there are ceremonies with readings which begin differently to the way they do in a Mass. For example, “Order for the Blessing of an Engaged Couple”:
“Brothers and sisters, listen to the words of the holy gospel according to John:”
This reading does not end with “The Gospel of the Lord” as it would at a Mass.
