"...increased the Sriptural readings in the Pauline Mass as evidence the Mass has been "protestantised." "

I don't think so. The Presbyterian church where I have a job (literal paying one) uses two scripture readings. And a Gospel is not always one of them. The Episcopalians use four readings, but not all the rest. Some, but not all. So much of the rest of Mass is from scripture.

So much of the rest of Mass is from scripture.

ALL of the Catholic Mass is from Scripture! Ask your priest to let you look at the Lectionary sometime. Every line has a Biblical reference, no kidding!
