They certainly are, and this "fact" is easily disproved by matching the Catholic lexionary to a list of chapters and verses in the Bible itself. We did exactly that on a thread back in 2009, with some interesting results, which I'll summarize:
Assuming a Catholic attended daily mass faithfully for three years (after which the Lectionary reading cycle ends), said Catholic heard 13.5% of the Old Testament (3378 verses), and 71.5% of the New Testament (5689 verses). That's 9067 out of 33001 verses mentioned in the lectionary, i.e. said Catholic heard 27.5% of the entire Bible (excluding Psalms) in the three-year reading cycle.
I still don’t see how you don’t see that we read the Bible. But it really is not going to ruin my day either way.
Pesky things those facts
