Gospel Readings

First Reading
This is the First reading take during every liturgical celebration. In most cases, it is take from the Old Testament. Most often it has related message with the Gospel Reading.
Responsorial Psalm
As its name implies, it is often take from the Book of Psalms. In most cases, especially on Sundays, Responsorial Psalms are song with marvelous and mild tone. Responsorial Psalms are often take by choristers.
Second Reading
This comes immediately after the Responsorial Psalm. Though, the Second Reading is not taken in every Mass, it is often taken in Sunday Masses and other Masses like Burial Mass. This Reading is often taken from the New Testament to point to the New Testament version of what we heard in the First Reading (Old Testament).
Gospel Acclamation
This comes immediately after the Second Reading while the Congregation stand to welcome the Gospel. Acclamation is begun with “Alleluia Alleluia”, but during Lent, we take “Glory and Praise to you, Lord Jesus Christ”. After singing this, one of the Reader will read a small verse of the Bible allotted as acclamation for the day. However, Gospel Acclamation is just as eye-opener to welcome the Gospel.
Gospel Reading
Gospel is taken by a Deacon or a a priest.  It is take from one of the Gospel authors – Matthew, Mark, Luke or John.
