Saint Aelia Flavia Flaccilla, known as Aelia Flacilla or Flacilla, was a Roman empress and may have been the daughter of Claudius Antonius, Prefect of Gaul. She was the first wife of Emperor Theodosius I. She was of Spanish descent. During her marriage to Theodosius, she gave birth to two sons, the future Emperors Arcadius and Honorius, as well as a daughter, Aelia Pulcheria.
Aelia Flacilla was a zealous supporter of the Nicene Creed, and she was considered a pillar of the Church and model of Christian virtue by Saint Gregory of Nyssa and others. She died in 385 of natural causes.
"The greatness of the good gift given her made her love for Him who gave it all the greater, so she bestowed every kind of attention on the maimed and the mutilated, declining all aid from her household and her guards, herself visiting the houses where the sufferers lodged, and providing every one with what he required. She also went about the chambers of the churches and ministered to the wants of the sick, herself handling pots and pans, and tasting broth, now bringing in a dish and breaking bread and offering morsels, and washing out a cup and going through all the other duties which are supposed to be proper to servants and maids. To them who strove to restrain her from doing these things with her own hands she would say, "It befits a sovereign to distribute gold; I, for the sovereign power that has been given me, am giving my own service to the Giver."

"It appears that, during the reign of Valens, had some dispute with his own clergy at Cyzicus, and had in consequence seceded from the Arians, and retired to Bithynia, near Constantinople. Here multitudes resorted to him; some also gathered from different quarters, a few with the design of testing his principles, and others merely from the desire of listening to his discourses. His reputation reached the ears of the emperor, who would gladly have held a conference with him. But the Empress Flacilla studiously prevented an interview from taking place between them; for she was the most faithful guard of the Nicene doctrines, and feared lest Eunomius might, by his powers of disputation, induce a change in the sentiments of the emperor."
