Teaching on Humility
Theodora's best-known teaching subordinates all ascetic effort to humility. She held that neither asceticism, nor vigils, nor any kind of suffering are able to save a person — only true humility can do so.
She illustrated the point with a parable of a hermit who sought to drive the demons from his cell. The demons agreed to depart only if he could name a single virtue they themselves lacked; unable to claim even one such virtue for himself, the hermit was left with humility alone, which she presents as the virtue victorious over the demons.
Sayings in the Apophthegmata Patrum
Theodora is one of only three women — with Syncletica of Alexandria and Sarah of the Desert — whose sayings were included in the Alphabetical and Systematic collections of the Apophthegmata Patrum. The collection as a whole preserves sayings attributed to twenty-seven abbases and three ammas, drawn from oral tradition first circulating in Coptic and later written down in Greek from the late fourth century onward.
Among her preserved sayings is a counsel on patience under insult: a devout person, when reviled, answered that he might have replied in kind, but that the law of God closed his mouth. Another records a rejoinder to a Manichaean who disparaged the body — that if one imposes the law of God on the body, it is shown to belong to its Creator. These sayings are edited in John Wortley's critical translation of the Alphabetical Sayings (St Vladimir's Seminary Press, 2014).
Identity and Conflation
Amma Theodora is repeatedly conflated with the penitent Theodora of Alexandria (Sep 11, OS-1820). Details belonging to the penitent — her flight to the desert disguised as a man to join a community of monks — are sometimes wrongly transferred to the amma, who was instead a widow and the leader of a women's monastic community.
Scholars have noted that the later legend of Apollinaris Syncletica was probably built upon the figures of Syncletica and Theodora of Alexandria, whose traditions were deliberately linked to enhance Syncletica's spiritual authority — evidence that Amma Theodora was a figure of sufficient early renown to be invoked in hagiographical narrative.
Commemoration
No fixed feast day for Amma Theodora is securely attested in the Eastern Orthodox calendar as distinct from the penitent Theodora of Alexandria (Sep 11). In the Western Anglican tradition she is honoured collectively with Ammas Sarah and Syncletica on January 5. Her Orthodox commemoration and canonical status warrant clergy and source review before publication.
