Why Are Verses Omitted?

[Guest Guest-ICTHUS]

This Sunday, at Mass, some verses were omitted from the New Testament lesson, most notably 1 Cor 10:7-9. Why were they omitted? Is it because they specifically warn against idolatry, and the Church is afraid that some people might hear them? That is what some of our separated bretheren would think.

And do not become idolaters, as some of them did, as it is written, "The people sat down to eat and drink, and rose up to revel."
8
Let us not indulge in immorality as some of them did, and twenty-three thousand fell within a single day.
9
Let us not test Christ 4 as some of them did, and suffered death by serpents.

If you notice, we often skips parts of certain passages in any given mass. This isn't because we are trying to hide anything, but merely because the readings are chosen to emphasize a theme together. The Old Testament Reading prefigures in some way the Gospel that will be read, and the New Testament Reading reveals something about the Gospel passage that is going to be read.

I have a feeling that the verse was skipped because it did not pertain to the theme being emphasized in the Gospel and readings.
