I was talking to a friend recently that is considering joining the seminary, reminding him that it would be a good idea to apply. Nearby was a friend of his that took the opposing view. When I asked why they were so insistent that joining was a bad idea they replied that they had taken up a contrary position to undo the 'swaying of his opinion' that I was trying for.
I promptly pointed out (kindly) that their action was no less an attempt at sway than mine and that in my opinion it was a really unnecessary thing to do. The position they had adopted was the position of the whole rest of the world and therefore did not need any help from them.
This might seem harsh but I think it's true. There are plenty of voices out there calling for young people to get married (a beautiful thing, if you're called to it) or, negatively, to do whatever they want, to indulge in whatever makes them feel good, to live a life in pursuit of goods and success. So why then, would it be necessary to fight against someone trying to argue for the religious life?
My point is not to make an example out of this person (honestly, only half seriously) playing the devil's advocate but to illustrate that the Church is the one whose case we ought to be helping plead.
As I said, the world has plenty of help but the Church could use a more laborers for the harvest, more fruit-bearing vines, more fishers of men.
As I urged two posts ago, if you know someone considering (or who ought to be considering) a counter-worldly vocation, don't be afraid to talk to them. If that person is you, don't be afraid to seek out information and to apply.
