The other betrayer was never mentioned by name but only referenced as "the disciple whom Jesus loved"
The underlining principle of embracing betrayal as a natural aspect of leading a healthy organization is covertly evident in these passages. John 21:18-19; John 13:14-30; Matthew 27:1-11; John 21:15-25; Psalm 41:9
I define betrayal as a good idea or person that knowingly or unknowingly exposes an organization, a group, and/or a person to danger. Fear of embracing betrayal limits the power and influence the Holy Spirit has on an organization.
It is important to note that not all danger leads to harm. Those that walk in the Spirit understand "...that in all things God works for the good of those who love him, who have been called according to his purpose - Romans 8:28
To him who has an ear let him hear:
18 Very truly I tell you, when you were younger you dressed yourself and went where you wanted; but when you are old you will stretch out your hands, and someone else will dress you and lead you where you do not want to go.” 19 Jesus said this to indicate the kind of death by which Peter would glorify God. Then he said to him, “Follow me!”
