Sorry, but for about 40 years, Vatican II didn't get to be promoted much. This was because we had two popes who thought that Catholicism should be like the church that they remembered from their boyhoods---provincial, 
and pretty isolated from the rest of Europe [Poland---isolated from Western Europe as well as North America].  So Vatican II is not past its expiration date.  Sadly too many Catholics are living as though the Church [which we all are] are still in the 1920's.


Vatican II DID focus on Jesus' teachings, especially in the Constitution "Dei verbum"---the Dogmatic Constitution on Divine Revelation.  From the Middle Ages through the Protestant Reformation to Vatican II----Catholics really didn't know what Sacred Scripture taught.  They had to depend upon the church leaders 'to tell them' like little children do.  With this document [and others as well] Catholic were urged to hold fast to the Scriptures through reading, study, and prayer.
