The significance of the last supper is evident in all but one of the following--...

The last supper was a significant event in the life of Jesus Christ and his disciples. It was a meal that Jesus shared with his disciples before his crucifixion, where he predicted his suffering and death. This event is also known as the Lord's supper or the Eucharist.

The question is asking which of the options is not significant to the last supper. Option A says that the last supper revealed Judas' betrayal of Jesus, which is significant because it shows how Jesus knew that one of his disciples would betray him. Option B states that Jesus predicted his suffering and death, which is also significant because it shows that Jesus was aware of his fate and that it was necessary for the salvation of humanity.

Option C, which is the correct option, suggests that the last supper was not significant in the re-establishment of the Lord's covenant with his children. This option is incorrect because the last supper was significant in the establishment of the new covenant. During the last supper, Jesus shared bread and wine with his disciples and said that the bread was his body and the wine was his blood, which would be shed for the forgiveness of sins. This act established a new covenant between God and humanity, where Jesus would be the mediator between God and his people.

Option D says that the last supper prophesied Peter's denial of Jesus, which is significant because it shows that even Jesus' closest disciples were not perfect.

In summary, the last supper was significant in many ways, including the revelation of Judas' betrayal, the prediction of Jesus' suffering and death, the establishment of the new covenant between God and humanity, and the prophecy of Peter's denial of Jesus. Option C, which suggests that the last supper was not significant in the re-establishment of the Lord's covenant with his children, is incorrect.
