One of the wonderful things about medicine is the insight it gives, on a daily basis, into humanity. After sufficient time, a physician learns to see, simply in passing, signs of illness or injury in other people. Problems past or present jump out to our eyes. As Christians, we should develop similar skills out of love. Given that the Church is called to be salt and light to the world, it makes sense for us to also serve as scouts, as “life-guards.” As such, we should be constantly on the lookout for the oppressed, the suffering, those subject to cruelty and tyranny, violence and harm. Unfortunately, in modern times one of the things we should be watching for is evidence of human trafficking. Tragically, all around the world human beings are bought and sold in enormous numbers as victims of such horrors. They are sold as sex slaves (forced into prostitution or other forms of sexual exploitation), as wage slaves (never making enough money to deliver themselves from unfair labor practices and contracts), and into frank slavery in everything from farms and factories to restaurants.
