My question, appearing as a duplicate question to what has been asked, identifies a scriptural reference that tells me that this disciple is not the apostle John, as the majority professes him to be. This makes this question 'unique'. I have provided my understanding of how this cannot be John and ask for others to evaluate my finding. I will provide my answer after my initial observation has been read, evaluated and commented on.
In John's gospel, Chapter 13, he first mentions 'the disciple that Jesus loved'. All of the references I have found indicate that John is this disciple, yet I cannot see how this could be true. The reason is verse 28.
But no one at the meal understood why Jesus said this to him.
John is the only apostle who wrote a gospel of Jesus Christ. John's accounts were either first-hand accounts, or were proven to be true to John so that he could write the truth of this event.
From John 13:
18 “I am not referring to all of you; I know those I have chosen. But this is to fulfill this passage of Scripture: ‘He who shared my bread has turned against me.’
19 “I am telling you now before it happens, so that when it does happen you will believe that I am who I am. 20 Very truly I tell you, whoever accepts anyone I send accepts me; and whoever accepts me accepts the one who sent me.”
21 After he had said this, Jesus was troubled in spirit and testified, “Very truly I tell you, one of you is going to betray me.”
22 His disciples stared at one another, at a loss to know which of them he meant. 23 One of them, the disciple whom Jesus loved, was reclining next to him. 24 Simon Peter motioned to this disciple and said, “Ask him which one he means.”
25 Leaning back against Jesus, he asked him, “Lord, who is it?”
26 Jesus answered, “It is the one to whom I will give this piece of bread when I have dipped it in the dish.” Then, dipping the piece of bread, he gave it to Judas, the son of Simon Iscariot. 27 As soon as Judas took the bread, Satan entered into him.
So Jesus told him, “What you are about to do, do quickly.” 28 But no one at the meal understood why Jesus said this to him.
John stated in verse 28 that no one at the meal, him included, understood why Jesus said what he did to Judas Iscariot. John would later learn who the betrayer was, but at this time he and the others did not know. As John stated he did not understand why Jesus said this to Judas, he could not be ‘the disciple that Jesus loved’.
So who is the disciple that Jesus loved?
