Biography

His date of birth is uncertain; died probably between 458 and 460; was distinguished during the period when the Eastern Church was convulsed by the Monophysite struggles, and was necessarily obliged to take sides in all those controversies. Those of his writings which have come down to us, though somewhat too rhetorical and involved, prove clearly that he was a man of great literary ability.

He was appointed Bishop of Seleucia in Isauria, between the years 432 and 447, and was one of those who took part in the Synod of Constantinople, which was summoned in 448 by the Patriarch Flavian for the condemnation of the Eutychian errors and the deposition of their great champion, Dioscurus of Alexandria. Curiously, though Basil seems to have agreed to these measures, he attended the Second Council of Ephesus

Second Council of Ephesus

The Second Council of Ephesus was a church synod in 449 AD. It was convoked by Emperor Theodosius II as an ecumenical council but because of the controversial proceedings it was not accepted as ecumenical, labelled a Robber Synod and later repudiated at the Council of Chalcedon.-The first...

 the next year (440) and induced probably more by the threats and violence of the Monophysite party than by their arguments, he voted for the rehabilitation of Eutyches and for the deposition of the Patriarch of Constantinople, and was thus regarded for a time as a supporter of Monophysite opinions.

Like the other prominent supporters of Dioscurus, he should have been removed from his see had he not in the meantime accepted the doctrine contained in the Dogmatic Epistle of Pope Leo I

Pope Leo I

Pope Leo I was pope from September 29, 440 to his death.He was an Italian aristocrat, and is the first pope of the Catholic Church to have been called "the Great". He is perhaps best known for having met Attila the Hun in 452, persuading him to turn back from his invasion of Italy...

 to Flavian, and joined in the condemnation of Eutyches and Dioscurus. After this period he seems to have continued a zealous opponent of the Monophysite party, who in the year 458 he joined with his fellow-bishops of Isauria, in an appeal to the Emperor Leo I, requesting him to use his influence in forwarding the Decrees of Chalcedon, and in securing the deposition of Timotheus Aelurus, who had intruded himself in 457 into the Patriarchate of Alexandria. This is the last reference we find to Basil, and it is commonly supposed that he died shortly afterwards.

, where is also his history of the protomartyr Thecla and of the miracles wrought at her grave. Most of these sermons may be regarded as genuine, though some of them are now generally assigned to Nestorius.

According to Photius, Basil also dealt in verse with the life and miracles of Saint Thecla

Thecla

Thecla was a saint of the early Christian Church, and a reported follower of Paul the Apostle. The only known record of her comes from the apocryphal Acts of Paul and Thecla, probably composed in the 2nd century.-Biography:...
