These people are not Catholics. She could have been baptized Orthodox as an infant (being Russian), but I am just guessing. To my knowledge the family does not practice religion. They are good people, just unchurched.If watches television all day and is on the Internet, and has the mentality of a 6 year old, then someone should stealthfully make sure that what she has access to nothing but good influences; Lives of the Saints, Bible stories, audiobooks, holy reminders, heaven, hell, purgatory, love for neighbor, missionaries at work, inspiring music, how to pray, etc. She’s not someone to be sterilized like an animal; she’s someone who has been put specifically in time within a specific circle of people, in order to provide them an opportunity to grow in holiness and gain merit through Christian love which is self-sacrifice.
Begin non-stop novenas for specific milestones. Also, send her picture and first name to good convents, especially those who have perpetual adoration, and specifically request fir prayers for her.
The worst possible thing is to allow her to fill her mind with all the poisonous noise that is Hollywood and the Internet. hopefully they can somewhat control what she feeds her mind with and has access to.
Write to Dr. Ray Guarendi about it.
As long as she is kept home, and her mother and neighbors can keep an eye on the situation, she is probably entirely safe. However, if she would ever have to go back into the co-ed group home, we have already seen in this thread an article from the National Catholic Bioethics Center, and a scholarly theological article that has some very good arguments for reluctantly administering temporary contraception in cases such as this.
There is no person on this forum who detests the deliberate and voluntary use of contraceptives more than I do. This sin, if accompanied by sufficient reflection and full consent of the will, has the potential to separate more people in the developed world from the grace of God, than probably any other mortal sin. It is basically mutual self-pleasuring. However, there is no question of voluntary fornication here. Mentally and spiritually, she is a child. If she were my daughter, and if I were in the sad predicament of having to send her to a facility where this danger exists, I would take these two articles to a priest faithful to the magisterium, and ask him if this sort of medication would be licit in our circumstances.
