Mirjana, one of the visionaries of Medjugorje, had a particular vision on 14th April 1982. While she was waiting for Our Lady to appear, Satan arrived disguised as Our Lady. She writes
"He was ugly, horribly ugly. You cannot even imagine how ugly, he almost killed me with his gaze, I almost fainted. He then told me,'You must leave God and Our Lady because they will make you suffer, come with me and I will make you happy in love and life.' My heart echoed -No, no, no! Then Satan went away and Our Lady came and she said to me:
"I am sorry for this, but you must know that Satan exists and has asked God to allow him to test the Church for a certain period with the intention of destroying Her. God allowed him to have one century, saying ,'You will not destroy Her.'
This century in which we are living is under Satan's power. When the secrets I have confided to you come about, his power will be destroyed. Satan has become aggresive because he is losing his power. He is breaking up marriages, causing quarrels amongst priests, obsessing people, even killing them.
Therefore, protect yourselves by prayer, fasting and, above all, community prayer. Renew the use of holy water, wear blessed and holy objects and put them in your homes."
