Final answer:
Judas Iscariot is the one who betrays Jesus Christ, leading to Jesus' mockery, flogging, and crucifixion according to the Gospel of Matthew 26.
Step-by-step explanation:
In the context of the Gospels in the New Testament, specifically the book of Matthew 26, Judas Iscariot is the one who will hand the Son of Man, referring to Jesus, over to the Gentiles to be mocked, flogged, and crucified. In the account, during the Last Supper, Jesus declares that one of His disciples will betray Him, which causes a stir among the apostles, each questioning if it was them. It is then revealed that Judas Iscariot, who reaches for the bread at the same time as Jesus, is the betrayer.
This narrative is a crucial aspect of the events leading up to the crucifixion of Jesus, who is ultimately handed over to the Roman authorities. The act of betrayal by Judas Iscariot plays a significant role in the Passion of Christ and has been depicted and discussed extensively in Christian theology and art.
