The requirement for someone to be totally detached from sin needs some explanation. No doubt it is the most difficult condition for obtaining the indulgence. Notably, however, the requirement is not freedom from all sin. Rather, it is freedom from attachment to sin; that is, that there is no sin which the soul is unwilling to renounce. A person should be able to tell if he is fulfilling this condition. An attachment involves a refusal to amend a situation, and a person should be able to tell if he has such an attachment. Sometimes, deep down, we really don’t want to let go of certain sins, be it gossiping or overeating or loafing on the job. This differs from the case of normal human weakness or where a person falls into the same sin many times before overcoming it. To souls such as these the Church is ready to open her treasury of aid.
