Matthew 24:23-25

Revised Standard Version Catholic Edition

²³ Then if any one says to you, ‘Lo, here is the Christ!’ or ‘There he is!’ do not believe it. ²⁴ For false Christs and false prophets will arise and show great signs and wonders, so as to lead astray, if possible, even the elect. ²⁵ Lo, I have told you beforehand.
