Never mind just the youth not being present at a mass. At Enoggera parish Brisbane there was just 39 in a church which could easily contain twenty times that number, for a vigil service. Other churches in Brisbane are also vacuous. One vigil mass had no hymns; nothing. But there was a homily on the asylum seeker business instead (never mind the history of Islam and its 370 million deaths etc).
It is so easily fixed.
The late Cardinal Martini in his last interview said of the church that it was “200 years out of date” , and “Our culture has aged, our churches are big and empty and the church bureaucracy rises up, our rituals and our cassocks are pompous”. (Wikipedia).
That began to change with Pope Francis, his Holy Thursday practice, and his deliberate rejection of the elitism.
But it has to trickle such a long long way before others pick up the story. A whole generation of American youth has gone from spiritual to carnal, which simple means no-one to take the priceless heritage of the Catholic church to the next generation.
Dr McGinn SJ, wrote in “Foundations of mysticism”, that the small ad hoc meet (prayer group) had a stronger tension and polarity (structure) than the wider church, which has only two prescribed days of fasting.

It has been said that 40,000,000 pilgrims have gone to Medjugorje, that 702,204 priests (some several times) have celebrated evening mass, that 502 priests and 123 nuns have received their vocation there. Medjugorje is the fastest growing pilgrimage site in the world.
Perhaps if some more of the clergy examined (and participated in) the Medjugorje event, a new life would grow in the most unexpected places in their parishes.
As Fr Tim Deeter, a supporter of Medjugorje, said once, that if someone came to him saying THAT IF IT WAS MORE THAN FOUR WEEKS SINCE THEIR LAST CONFESSION, THEY WERE VISITORS FROM A NEIGHBORING PARISH.

Perhaps a little less know how and a little more know why, as someone put it once.
