Ah! like a teacher saying "All instruction is good for you, but not everything will be on the test...."
years later some instructors found that ^^ confusing as well.
so they just started leaving out the instruction and just 'taught the test'.
What they found was that test scores went up, but SAT scores went down....
go figure.
The reason was that the students had the answers
but they didn't have the 'why' behind those answers.
So while they could pass a test, they couldn't apply what they had learned.
on a personal note i would rather have the pastoral guidance retained and valued for what it is in Lumen Gentium,,
rather than to have it thought of as something of lesser importance, and thus easily disposed of if inconvenient.
