Our whole reading of the third theme of GC 26 (Vocation Ministry) is faulty (mine included). I thought it was all about vocations to Salesian life; but I admire the presentation of this idea in GC 26 documents. It does not restrict the meaning of 'Vocation Ministry' to 'Salesian vocation ministry'; it rather promotes a culture of vocations. Therefore through the four guidelines in that section (8 - 11), it builds up a Culture of Vocation to life, consecrated life and Salesian life. The last guideline, dwells with the two forms of living the one Salesian vocation: as Brothers and Priests.
When understood in this sense, the whole idea of vocations to Salesian life/consecrated life as the crown of our youth ministry will make sense. Otherwise, vocation promotion will be seen as another 'activity' among the many, and so will youth ministry!
