Origen, kwa Kigiriki Ὠριγένης Ōrigénēs, (185 - 253), mwana wa mfiadini Leonidas wa Aleksandria, alikuwa padri kutoka Aleksandria (Misri) aliyehamia Kaisarea (Palestina) na kuendeleza kazi yake kama mtaalamu maarufu wa Biblia.. Yesu, miguu yangu ni michafu. Njoo kama mtumwa kwangu, mimina maji katika beseni lako, njoo unitawadhe miguu. Ninapoomba hivyo najua kuwa nathubutu mno, lakini naogopa tishio lililotolewa uliponiambia, “Nisipokutawadha miguu, huna ushirika nami”. Basi, osha miguu yangu, kwa kuwa naonea shauku urafiki wako.
