The Holy Bible warns us

The Holy Bible warns us that Satan "transforms himself into an angel of light" to deceive. The incidents in which Christians, even monks, fall victim to deceptive demonic appearances are fully reflected in what is being published by the Holy See. Ὁσίου Νικοδήμου "Γεροντικόν περί ὀνείρων και ὁραμάτων".

 Γνωρίζομεν ἀκόμη ἐκ τῆς Ἁγίας Γραφῆς, .τι καί «ν «ἄγγελος ἐξ οὐρανοῦ εὐαγγελίζεται ἡμῖν, παρ 'ὅ παρελάβομεν» «ἀνάθεμα ἔστω». For this every preaching union which harms the saving Truth of the Church can not be accepted, as a consul of confusion and loss, much later, when τους Ἁγίους Πατέρας, ἀλλά εἰς ὁράματα ἁπλοϊκῶν Χριστιανῶν, οἱ ῖποῖοι ἀνακρύσσουν τους ἑαυτούς των Προφήτας. ἀπό τους Ἁγίους Ἀποστόλους.
