I guess nobody told her that you have to be truly sorry for your sin and to make a firm resolve never to do it again before you get forgiveness. Christ realized that people would make mistakes and He provided a way for them to face their sins and repent. She’s really quite ignorant about the Catholic faith.
She is very ignorant about Catholocism and I think she should be held accountable for what she said, but of course she never will be. It’s not like anyone who interviews her will bring it up.
She needs to do nothing more than to ask God for forgiveness, to say The Lords Prayer as Christ told the masses on The Sermon on the Mount to do. From there she need only to find the nearest Catholic church in her area, ask the monsignor or a priest there to baptize her in the Name of The Lord and start attending Mass. She should also ask to hear her confession heard as well. It’s no big deal to become one with the True Faith and the true Church. We hate the sin and love the sinner. Our faith is about the love Christ preached, not castigating people because they’ve chosen a false path previously.
