Is it proper to call sins of grave matter "mortal sins"?


Since the nature of the action is only one of three criteria for mortal sin it seems like making the blanket statement “_____ is a mortal sin” is incorrect because some people do not commit a mortal sin when they commit ______. So, is it proper to call sins of grave matter “mortal sins”?




Dear JP,

The objective identity that makes a sin mortal is that it consists of grave matter. The other two requirements have to do with the person’s SUBJECTIVE ability to sin mortally. So it is correct to say that sins of grave matter are objectively, mortal sins.
