It is painfully clear that you have never attended a Catholic Mass.
LITURGY OF THE WORD
This part of the Mass will offer Scripture readings from the following areas:
First Reading A scripture reading from the Old Testament
Responsorial Psalm A Psalm selected from the Book of Psalms. The congregation interacts by offering a response (usually sung).
Second Reading A scripture reading from the New Testament
Gospel Acclamation The people praise Christ's presence in the sacred Word of God.
Gospel Reading Taken from one of the four Gospels of either Mathew, Mark, Luke or John.

>>I have heard Catholic services on the radio. I heard readings from the gospels, but no readings, no sermons, from the epistles - the epistles, where it is always Christ, and NEVER Mary, that is mentioned.
Just relating my experience, though only radio, of Catholic services.
