You are not telling the truth or you weren’t listening. EVERY Catholic Mass has the Gospel read and a New Testament reading and and Old Testament reading and a Psalms sung.
Not a single one of those is a presentation of the Gospel Message that saves.
"It is a trustworthy statement, deserving full acceptance, that Christ Jesus came into the world to save sinners, among whom I am foremost of all." (I Timothy 1:15)
The Gospel Message is the plan of Salvation.
I did not say no scripture is read. I did not say a passage from Matthew, Mark, Luke, or John was read.
