Erastus (Greek: Ἔραστος, Erastos), also known as Erastus of Paneas, is a person in the New Testament. According to the Epistle to the Romans, Erastus was a steward (Greek: οἰκονόμος, oikonomos) in Corinth, a political office of high civic status. The word is defined as "the manager of household or of household affairs" or, in this context, "treasurer"; The King James Version uses the translation "chamberlain", while the New International Version uses "director of public works". A person named Erastus is also mentioned in the 2 Timothy and Acts, and these mentions are usually taken to refer to the same person.
According to the tradition of the Orthodox Church, Erastus is numbered among the Seventy Disciples. He served as a deacon and steward of the Church at Jerusalem and later of Paneas in Palestine. The Church remembers St. Erastus on January 4 among the Seventy, and on November 10.
Erastus of Corinth Wikipedia
And having sent into Macedonia two of his helpers, Timothy and Erastus, he himself stayed in Asia for a while.
Gaius, who is host to me and to the whole church, greets you. Erastus, the city treasurer, and our brother Quartus, greet you.
Erastus remained at Corinth, and I left Trophimus, who was ill, at Miletus.
In 1929, an inscription mentioning an Erastus was found near a paved area northeast of the theater of Corinth. It has been dated to the mid-first century and reads "Erastus in return for his aedileship paved it at his own expense." (Latin: ERASTVS. PRO. AED. S. P. STRAVIT abbreviated for ERASTUS PRO AEDILITATE SUA PECUNIA STRAVIT.) New Testament scholars have identified this aedile Erastus with the Erastus mentioned in The Epistle to the Romans but this is in dispute. This debate has implications relating to the social status of the members of the Pauline churches.
Troparion (Tone 3)
Holy Apostles, Erastus, Olympas, Herodion, Sosipater, Quartus and Tertius,
entreat the merciful God,
to grant our souls forgiveness of transgressions.
Kontakion (Tone 2)
Illumined by divine light, O holy apostles,
you wisely destroyed the works of idolatry.
When you caught all the pagans you brought them to the Master
and taught them to glorify the Trinity.
