Most Catholics don't read the Bible. Most Christians don't. People find a bit here and there that they like, and run with it.
For that matter, when my father in law died, the priest asked me for some good verses on being a farmer. He knew I was LCMS from the “old” school and was forced to memorize half the Bible by age 10! But that is a rarity.
There are MANY Bible verses that one is allowed to pick from for a funeral Mass. Obviously your relative was a farmer and the Priest was being nice and accomadating to you to pick out your OWN!! You took it that he didn't know the Bible.....you are wrong....he was being thoughful to you!
Thank you. A blanket statement is mostly wrong — thank you both for correcting rn
