I came back to the church nearly 2 years ago and went to confession. After several confessions of mentioning past mortal sins I was told not to mention the past again. I have been to several confessors since and they have let me bring up some sins and then told me not to mention any more mortal sins from my past. I have been told on numerous occasions that by saying that I have sinned against the 6th commandment that I need not mention any more sins of impurity from the past. I have completely stopped committing any of these sins of impurity since my return to the church.However there are some past sins of impurity that I have not yet confessed.
I understand that the church requires you to confess all mortal sins from the past. Should I go by the advise I have been given by these priests.
