Judas Iscariot
Judas Iscariot (died AD) was a disciple and one of the original Twelve Disciples of Jesus Christ. According to all four canonical gospels, Judas betrayed Jesus to the Sanhedrin in the Garden of Gethsemane by kissing him and addressing him as "Rabbi" to reveal his identity to the crowd who had come to arrest him. His name is often used synonymously with betrayal or treason. Judas's epithet "Iscariot" most likely means he came from the village of Kerioth, but this explanation is not universally accepted and many other possibilities have been suggested.
Petrus Alphonsi
The polemics between Moses and Peter seemed to have a friendly tone in their voices, but the arguments that the "Dialogi" presented were a radically new way to attack Judaism. It was far more negative than any of the Latin works influenced by the Augustinian tradition. Alfonsi viewed Judaism as a conspiratorial, anti-Christian sect. Although he claimed that Judaism did follow the Old Law, he said that it is “only in part, and that part is not pleasing to God.” He also challenged the general idea that the Jews unknowingly killed the son of God, and said that they killed Jesus out of envy. He said that, “God revealed to their priests the Temple would be destroyed and the Jews scattered as punishment for the Crucifixion; the priests, out of malice and envy, hid this revelation from their people.”
