Indeed - no surprise, sadly enough.
“In her writings, she recounts how the Virgin Mary and Child Jesus appeared to her on other occasions, years after the initial apparitions.”
Gnosticism.
No one is required by the Catholic Faith to put credence in apparitions and other mystical experiences -- not even the one who personally receives these visions and messages, and not even when they are found free of doctrinal error by the bishop.
The Catholic Church teaches that there is nothing contained in "private revelation" which is necessary for salvation.
This is not to say that such visions and so forth are valueless. Only that they are not de Fide.
A Gnosticism charge from you? Kosta, you may want to comment on this. ;-)
Scripture itself tells us that Jesus took Peter, James and John up a mountain with him and was transfigured before them, while speaking with Moses and Elijah who were visible to the apostles. St. Paul mentions his own mystical experiences in his letters. The entire last book of the Bible was received in a vision.
Mystical experiences have always been an authentic part of Christianity.
Ignorance, on your part.
