Passages that didn’t make any sense before starts to make sense when one realizes TDWJL (the disciple whom Jesus loved) is Lazarus, not John the apostle.
Jhn 18:15-17 And Simon Peter followed Jesus, and [so did] another disciple: that disciple was known unto the high priest, and went in with Jesus into the palace of the high priest. 16 But Peter stood at the door without. Then went out that other disciple, which was known unto the high priest, and spake unto her that kept the door, and brought in Peter. 17 Then saith the damsel that kept the door unto Peter, Art not thou also [one] of this man’s disciples? He saith, I am not.
If the disciple was John, how did the high priest know about John? But, if it was Lazarus, the high priest would’ve known him because they earlier were trying to kill him.
Jhn 12:10 But the chief priests consulted that they might put Lazarus also to death;
Passages mention that all the disciples fled and forsook Jesus when he was arrested.
Mat 26:56 But all this was done, that the scriptures of the prophets might be fulfilled. Then all the disciples forsook him, and fled.
The only exception mentioned is Peter. All the synoptic gospels record Peter secretly following Jesus and then denying him.
Mat 26:58 But Peter followed him afar off unto the high priest’s palace, and went in, and sat with the servants, to see the end.
Mar 14:53-54 And they led Jesus away to the high priest: and with him were assembled all the chief priests and the elders and the scribes. 54 And Peter followed him afar off, even into the palace of the high priest: and he sat with the servants, and warmed himself at the fire.
Luk 22:54 Then took they him, and led [him], and brought him into the high priest’s house. And Peter followed afar off.
There is no mention of John in these passages. So, John 18:15-17 makes the most sense if the other disciple was not John, but Lazarus.
