“The execrable and hitherto unheard of abuse has grown up in our day, that certain persons, imbued with the spirit of rebellion, and not from a desire to secure a better judgment, but to escape the punishment of some offense which they have committed, presume to appeal to a future council from the Roman Pontiff, the vicar of Jesus Christ, to whom in the person of the blessed PETER was said: "Feed my sheep" [John 21:17], and, "Whatever thou shalt bind on earth, shall be bound in heaven" [Matt. 16:19]. . . . Wishing therefore to expel this pestiferous poison far from the Church of Christ and to care for the salvation of the flock entrusted to us, and to remove every cause of offense from the fold of our Savior . . . we condemn all such appeals and disprove them as erroneous and detestable.”  Pope Pius II, “Exsecrabilis”, Jan. 18, 1460:
