"The quality of the clergy depends on the soundness of their formation," said the Pope in his address to the seminarians.A little more from the story at CNA
In addition to studies, seminarians should receive an "integral formation, centered on the spiritual dimension," whose "pillars are the daily sacrament of the Eucharist and the sacrament of confession."
Benedict XVI also recalled how the study program "was incorporated within a framework of integral formation, focusing on the spiritual dimension and having as its pillars the Sacraments of the Eucharist (every day) and of Penance (at least once a month), and supported by the devout practices prescribed or encouraged by the Church. Great importance was also given to education in charity, both in everyday fraternal life and in helping the sick, and in what today we call 'pastoral experience'."[Hmm. I'm coming due on that "once a month" confession thing. And given the situation here, I really can't make it to Mass every day ... but boy, do I hunger for it come weekend!]
