Sports can bring out the worst in people...
So can posting on the religion forum of Free Republic.
Just about anything can bring out the worst in people. Missals at Mass can bring out the worst in people. How many times have you heard somebody bugged when the priest (or lector) fumbles over or skips a word? "Oh, that idiot again. Will he never learn to read?" Is it the missal causing them to sin - or their own imperfectly prepared hearts?
Or how about the old lady fingering her Rosary and saying Hail Marys during the consecration? Should we forbid the Rosary in Catholic Churches? And, unlike sports, the Rosary isn't even a moral neutral.
But it's the same principle. Just because there are some who fall into sin, it does not mean sports are bad. In and of themselves, sports are morally neutral, but they can also be an excellent tool for forming a child's (particularly a boy's)moral foundation. I cannot imagine raising a physically healthy boy up to moral adulthood without exhausting him physically during his teenage years. And sports is one way to do this.
And we can pray that with Our Church's guidance, children who would otherwise be sitting home watching MTV and playing video games will be out learning focus, determination, and good sportsmanship. If a child does not learn that swearing is unacceptable from his parents, where else can he learn it? I'll tell you where - from his Catholic coach. There is so much good that can be done with sports, I really believe the Pope is onto something good.
