Of course she should see a priest, but we can examine our own consciences and know whether or not we gave consent to an act of mortal seriousness. I did not forgive anything, but only said that if she was compelled, she is not culpable. This is in the catechism, not something coming from me. Some people think that if a woman gets an abortion and didn’t have to be tied down, then she is excommunicated. That is simply not true.
She is capable of knowing whether she consented to what she did or not. This is why we are taught in catechism as first and second graders that a mortal sin requires an act of will, that it isn’t simply a matter of the seriousness of the act. I did not make up the passage of canon law that I cited. Part of examining our consciences before we go to confession is examining whether or not we *freely *chose to do what we did. We don’t have to be totally unfettered by pressure, but there is a point! It makes a difference, and the priest cannot read minds. When we confess having done something, we are saying that we are responsible for the choice.
Having said that, it is by far the safest to ask a confessor to help us with this, if there is any danger that we are in self-denial about our part in choosing the action. I don’t think she will really be able to convince herself that this is not on her head until she does this, and that healing is what everyone wants for her, whether she is 0% responsible or 100% responsible. On that account, I agree with the advice that she talk to a priest about this in the confidentiality of confession at her first opportunity.
What she should not do is to fear to tell a priest about this. Here in Oregon we have a man who murdered one person, was sent to prison, and murdered another person after being sent to prison, and notoriously fought for the right to be executed, to have a court overrule the governor, who deferred his execution. That man repented from his sins and was confirmed in the Catholic Church by our Archbishop this spring. There is never a reason for someone with sorrow over a gravely wrong action to ever fear coming to a priest for healing. You are right: It is the priest’s office to discern what is needed to accomplish that healing. What is mainly important is that the person who is turning away from the whole matter not fear at all coming to talk to her pastor about it.
