"What is the Worst Sin?"

By Paul Dion, STL, ParishWorld Theology Editor

Rarely do we at dedicate so much space to "sin". This time we do. Since we celebrate the mystery of the breadth and the depth of God's love and glory, we grow up with the deep faith that He has the power to create, to support and to save anyone. is a part of that faith and we are happy that you accompany us down the road of faith.

Interestingly there are other forces on the Internet that are not as positively dedicated as we are. Sometimes questions do arise about sin and its consequences. Lately there has been a discussion about the worst sin. It seems to be a strange question.

Every sin insults God, and what could be worse than that? In the same thought, every sin insults His creatures too, including the sinner himself. So often, when we consider the concept of sin, we don't include ourselves as being the object of our own insult. We insult our souls, our heart, our mind, our body, our family and the wider community of those with whom we keep company every day.

So, allow us to ask the question, "What is the Worst Sin?" Consider this question not only in the context of an insult to God, but in the context of the greatest possible damage that we could do both to God and to ourselves through sin.

What do you think it is? We'd love to hear your thoughts.

  1. I would say there could be a number of candidates. If we think of the Capital or Deadly sins, the chief sin of those is pride, because all the others is rooted in pride; it is the non serviam of Satan.

    Secondly, we can think of the 5 sins which cry out to Heaven for vengeance, remember those in your old Baltimore? Some of them being the Sin of Sodom, giving an unjust wage, etc.

    But, I would say the worst sin is the unforgivable sin, which Scripture tells us is the sin against the Holy Ghost. This is generally seen as what is called "final impenitence"-- final rejection of salvation.

    Mr Dion, I just read your answer to the burning question. And this is some really deep stuff. Had to read it twice to get to what you really meant. But you are oh so correct. How can we be so blind. Guide us O Holy Spirit!
