Lol. I THINK the message is that every culture that ever was, is and will be generally had, has and will have the basic crimes and sins that encompass our very own ten commandments. Not much new in the way of sin.
The Catholic (catholic means universal) Church embodies Jesus as the Savior of humanity. He died for all our sins. We owe Him our undying gratitude for that.
The least we can do is try to live out our lives doing what Jesus wants us to do:
Love God and love each other. It's simple and pure but not often easy.
It is our duty and our salvation. Some people have spiritual disabilities for lack of a better word. Those who stumble at the word Catholic/catholic may do better if they use the word Christian, although they must needs love their Catholic brethren. Love covers a multitude of sins.
