From the comments:
Something few English speakers realize is that when Pilate asked Jesus "What is truth?" in John 18:38, the phrase in latin is "Quid est veritas?" which is an anagram for "Est vir qui adest." Which translates to "The man in front of you."
Pilate answered his own question
"The declared enemies of God and His Church, heretics and schismatics, must be criticized as much as possible, as long as truth is not denied. It is a work of charity to shout: ‘Here is the wolf!’ when it enters the flock or anywhere else." -- Saint Francis de Sales
"For there shall be a time, when they will not endure sound doctrine; but, according to their own desires, they will heap to themselves teachers, having itching ears:" [2 Timothy 4:3]
