Basil of Seleucia

Bishop of Seleucia in Asia Minor (c.448-458). He probably contributed to the Definition of Chalcedon the phrase “known in two natures.” Although a correspondent of the pro-Monophysite Dioscorus, he condemned Eutyches* at the Home Synod (Constantinople, 448), but at the Ephesian Robber Synod* (449), where Dioscorus was prominent, he supported Eutyches and withdrew his earlier claim to worship “our one Lord Jesus Christ made known in two natures.” Almost deposed at Chalcedon (451) for this, he based his vacillation on intimidation and recalled his orthodoxy in 448, adding that he had already signed the Tome of Leo. His extant writings include forty-one sermons, seven homilies, and a legendary account of St. Thecla.
