“[Judas] had been treated by Jesus himself, in all external things, as if he had truly been a disciple, even investing him with the character of apostle, sending him forth to preach the gospel, and enduing him with miraculous gifts of the Spirit. For though Christ knew him, yet he did not then clothe himself with the character of omniscient Judge, and searcher of hearts, but acted the part of a minister of the visible church (for he was his Father’s minister;) and therefore rejected him not, till he had discovered himself by his scandalous practice; thereby giving an example to guides and rulers of the visible church, not to take it upon them to act the part of searcher of hearts, but to be influenced in their administrations by what is visible and open.”
Jonathan Edwards
"Judge not, that you be not judged. For with what judgment you judge, you shall be judged: and with what measure you measure, it shall be measured to you. And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye? Or how wilt thou say to thy brother, Let me cast out the mote out of thine eye; and lo, the beam is in thine own eye? Thou hypocrite, cast out first the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother's eye." Matthew 7:1-5
