‘Modern psychology has taught us much about sibling rivalry, believed to be among the primary relations that form a life, with the potential to really mess it up. Research gleaned from the analyst’s couch is corroborated by Scripture. Think of Cain and Abel, Jacob and Esau, Leah and Rachel. What twistedness, what pain, we see in these pairs of brothers and sisters! It is interesting, then, that in recruiting for the apostolic college, seeking heads for the Twelve Tribes of the New Israel, Christ should have wished a high percentage – one-third – to be blood brothers. If Christ assumed these complications into his closest band of followers, it was perhaps to show that natural limitations, relational conditioning, can be overcome if we truly become disciples. James and John, Peter and Andrew, grow in faith and stature through the Gospel account, to the extent that, after Christ’s rising, they are ready to be sent, each with his itinerary, to the ends of the earth, to proclaim life’s victory. They’ve grown up. They’ve left themselves behind. Thus they’re freed for mission.’ From Entering the Twofold Mystery.
