The church of Saint Pope Eleutherius at Constantinople was served by a reader named Carisius, who led a disorderly life.

When both measures proved ineffectual, the patriarch prayed to Eleutherius to either correct the unworthy reader or to take him from the world.

Theodorus also relates how a painter, presuming to depict the Saviour under the form of Jupiter, had his hand withered, but was healed by the prayers of Gennadius.

[4] About the same time Daniel the Stylite began to live on a column near Constantinople, apparently without the permission of the Patriarch or the owner of the property where the pillar stood, who strongly objected to this strange invasion of his land.

At the end of the rite, however, the patriarch ascended to give Holy Communion to the stylite and to receive it from him.

It seems not later than 459, Gennadius celebrated a great council of 81 bishops, many of whom were from the East and even from Egypt, including those who had been dispossessed of their sees by Timothy II of Alexandria.

[3] The continuation of Jerome's Chronicle by Marcellinus Comes tells us (according to some manuscripts) that Gennadius commented on all epistles of Paul of Tarsus.

[3] Gennadius wrote a commentary on Daniel and many other parts of Old Testament and on all the Pauline epistles, and a great number of homilies.

The principal fragments of his biblical works include Genesis, Exodus, Psalms, Romans, 1 and 2 Corinthians, Galatians, and Hebrews, and are interesting specimens of 5th century exegesis.
