Another quote says that if a person is a heretic and dies, the followers will scatter. I believe it’s from St. Paul.
Knowing the context and the scripture is usually helpful
This was a prophetic utterance of Jesus
31Then Jesus said to them: All you shall be scandalized in me this night. For it is written: I will strike the shepherd, and the sheep of the flock shall be dispersed. 32But after I shall be risen again, I will go before you into Galilee. 33And Peter answering, said to him: Although all shall be scandalized in thee, I will never be scandalized. 34Jesus said to him: Amen I say to thee, that in this night before the cock crow, thou wilt deny me thrice. 35Peter saith to him: Yea, though I should die with thee, I will not deny thee. And in like manner said all the disciples. (Mt. 26:31-35)
I believe the following is from History...
Pope Stephen VI (896–897), who had his predecessor Pope Formosus exhumed, tried, de-fingered, briefly reburied, and thrown in the Tiber.[1]
Pope John XII (955–964), who gave land to a mistress, murdered several people, and was killed by a man who caught him in bed with his wife.
Pope Benedict IX (1032–1044, 1045, 1047–1048), who "sold" the Papacy
Pope Boniface VIII (1294–1303), who is lampooned in Dante's Divine Comedy
Pope Urban VI (1378–1389), who complained that he did not hear enough screaming when Cardinals who had conspired against him were tortured.[2]
Pope Alexander VI (1492–1503), a Borgia, who was guilty of nepotism and whose unattended corpse swelled until it could barely fit in a coffin.[3]
Pope Leo X (1513–1521), a spendthrift member of the Medici family who once spent 1/7 of his predecessors' reserves on a single ceremony[4]
Pope Clement VII (1523–1534), also a Medici, whose power-politicking with France, Spain, and Germany got Rome sacked.
Oh the above weren’t HERETICS; just SINNERS!
Like ALL of us.
