There are many miracles that happened outside of the CC. The CC does not own exclusive rights to miracles. People getting healed, marriages saved, people getting miraculously saved etc. But if you are looking at approved apparations, you will not find any. The CC will not automatically approve an apparation. They have to cease, investigated, the seer is checked, investigated to see if they are psychologically sound, what if any were the messages, are they in line with the teachings of the church, etc., etc., and then maybe they may be deemed worthy of believe. Protestant Churches have nobody with authority to render any such apparations worthy of believe. Besides, if something was approved by some pastor or a non-catholic bishop, that would be too, too Catholic to suit them.
