Saint Euthymios, Patriarch of Constantinople, confessor.
Saint Euthymios was a monk and spiritual father to Emperor Leo the Wise before being raised to the patriarchal throne of Constantinople in the early tenth century. He was deposed and exiled amid the disputes over the emperor's fourth marriage.
He bore his exile patiently and reposed in a monastery, being honoured by the Church as a confessor.
