Theodori wa Tabennese (314 hivi - 27 Aprili 367) alikuwa mwandamizi wa kiroho wa Pakomi na alizuia shirikisho la kwanza la monasteri ya Kikristo lisiishe na kifo cha huyo mwanzilishi wake. Zimebaki hotuba zake kadhaa katika maandishi ya wafuasi wake. Tangu kale anaheshimiwa na Wakatoliki, Waorthodoksi na Waorthodoksi wa Mashariki kama mtakatifu. Sikukuu yake huadhimishwa siku ya kifo chake au tarehe 16 Mei, siku inayofuata sikukuu ya Pakomi. Watakatifu wa Agano la Kale Orodha ya Watakatifu Wakristo Orodha ya Watakatifu wa Afrika Orodha ya Watakatifu Wafransisko The monastic chronicle of the Pachomian federation is by far the most detailed source that mentions Theodorus. The chronicle was completed sometime after the deaths of Pachomius and Theodorus, who are presented as the two centermost figures in the history of the Koinonia. Versions of this chronicle has been found in several different translations and pieced together from fragments but the Bohairic version has become the most frequently consulted. This is because it is by far the most detailed and comprehensible version, and written in a language more similar to the Sahidic Coptic spoken by most Pachomian monks than the Greek version.
