Matthew 7:15-20
New King James Version (NKJV)
You Will Know Them by Their Fruits
(15) “Beware of false prophets, who come to you in sheep’s clothing, but inwardly they are ravenous wolves. 16 You will know them by their fruits. Do men gather grapes from thornbushes or figs from thistles? 17 Even so, every good tree bears good fruit, but a bad tree bears bad fruit. 18 A good tree cannot bear bad fruit, nor can a bad tree bear good fruit. 19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 Therefore by their fruits you will know them."

Michael Voris has an excellent piece up on his site at ChurchMilitant.TV where he talks about the failure of the Catholic clergy and describes them as wolves in shepherds clothing. Very good and you can watch it here.
