Back in 2006 we posted an article entitled "Lectionary censorship" (Musings, July 11, 2006) about large swaths of Biblical teaching withheld from parishioners on a regular basis by those who typically use the "Shorter Form" lectionary readings in the Novus Ordo liturgy.
What reminded us of this was a post entitled "What does the Bible really teach?" (The Nesciencent Nepenthene, April 6, 2015) based on a comparison of what can be found in the April 5 Easter Sunday readings with what is actually in the Bible. Pretty amazing.
This leads me to think there is a good research project here for someone willing to undertake the foot work. The discrepancies are simply scandalous.
