Theodora of Constantinople was a tenth-century holy woman who, after a life of marriage and early widowhood, devoted herself to caring for the destitute and eventually embraced the monastic life under the spiritual direction of Saint Basil the New. The sources place her in Constantinople during the first half of the tenth century, where she lived the monastic life in a solitary cell within her own home. She is commemorated by the Orthodox Church on December 30.
According to the tradition, Theodora had been married but was widowed early, after which she led a pious life devoted to the poor and the hopeless. As a nun she became a disciple and servant of Saint Basil the New, a noted ascetic of Constantinople (commemorated March 26). The synaxarion relates that she died in great old age in the year 940.
Theodora is best known not for the events of her earthly life but for an account associated with her after her death. By tradition, Saint Basil the New granted his disciple Gregory a vision in which Theodora described the passage of her soul through twenty aerial toll-houses, where evil spirits presented records of her sins and angelic defenders answered with her good deeds, while a store of spiritual gifts supplied through Saint Basil's prayers assisted her. This narrative, transmitted through the life of Saint Basil the New, became one of the principal sources for the Orthodox tradition concerning the soul's journey after death.
