There is something to be said for creating a tribal identification with life changing groups, and experiences. That is what Carlos did with the Celtic Cross up on the wall of The Vault.
Carlos got the tatoo, because he identified with the mission and message of The Gathering, and has been experiencing some signifacnt change in his relationship with God. The tatoo was like a rite of passage, and it has a tribal indentification.
see Carlos' Tatoo here.
