Undoubtedly these schools pose a great danger to the Muslim who is ignorant of Islam and its teachings, because they give lessons and teach information in which there is approval and praise of the kaafirs and their religions and beliefs, and usually attack Islam and condemn the Muslims. But if the student in these schools has a sound understanding of the beliefs of Islam, and knows the pillars of Islam and what is halaal and what is haraam in Islam, and he needs to go to such a school in order to learn a skill or profession or a gain specific knowledge, and he is confident that he will not be influenced by their lessons and teachers, and he will not be forced to learn any of the subjects that have to do with Catholicism, then in that case we think that it is o.k. for him to study there. Rather we worry about one who is ignorant and does not understand the plots of the kaafirs and their tricks against the Muslims. But whoever is confident and adheres to the beliefs and practices of Islam, then usually such a person would not be affected by their teachings and practice.
