I dont know how dead this topic is, but if anyone's interested, in the catholic church there are a few ways to classify sins. Although it DOES make sense, the word 'cardinal' is not used in the catholic church to classify sins, however, the word 'carnal' is ... meaning 'physical'. it is usually in reference to a sin of sexual indulgence, and that word fits perfectly, espically if shes referring to cheating in a relationship.
And i am talking from YEARS of catholic school and church o.o
