We Catholics cannot avoid the demand of evangelization, of proclaiming the faith. Vatican II couldn't be clearer on this score, seeing the Church itself as nothing but a vehicle for evangelization. According to Vatican II, it's not so much the case that the Church has a mission, but rather that a mission has the Church. Bringing people to Christ is not one work among many; rather it is the central work of the Church, that around which everything else that we do revolves.
 

Do we need evangelization? The statistics couldn't be clearer. Did you know that there are nearly as many ex-Catholics as Catholics in this country? Did you know that by some estimates, between 50 and 80% of those who attend the Protestant mega-church of Willow Creek are former Catholics? Did you know that the fastest-growing category in those polls of religious affiliation is "none?" Did you know that a recent survey shows that among young religious people, those with the worst sense of their own tradition are Jews, but that the second to last are Catholics?
