A number of my liberal Christian friends are excited about the news that a group of Catholics have declared union busting to be a mortal sin. As the daughter of two teachers, I’m fairly pro-union, but this kind of thing always seems excessive to me. It feels like people twisting theology to make sure that their pet issue is recognized. Mortal sin, venial sin, or just plain secular wrong, the point is that you oughten’t do it. The specific hierarchy of erring feels less important.
The scholars explained that under church teaching, such a right is rooted in divine law and that efforts to break a labor organization using civil laws is comparable to idol worship, which is contrary to the First Commandment.
