Erastus, from a Greek word pronounced er-as-tos, meaning beloved, was the name of two men (or possibly the same man) who converted to Christianity (see also Christianos) from the preaching of the apostle Paul (see Paul's Ministry). One Erastus is described as "Erastus the chamberlain of the city" of Corinth, while the other is described as a traveling preacher of the Gospel with Paul and Timothy, although his home city was also Corinth i.e. "Erastus abode at Corinth." (see below).
"So he sent into Macedonia two of them that ministered unto him, Timotheus and Erastus"
There were times that The Lord empowered Paul with great miraculous power, as a witness of the power of the only true God. Such displays produced much fruit. Erastus was at that time both a convert and an associate of Paul.
"And God wrought special miracles by the hands of Paul: So that from his body were brought unto the sick handkerchiefs or aprons, and the diseases departed from them, and the evil spirits went out of them" (Acts 19:11-12 KJV)
"And this was known to all the Jews and Greeks also dwelling at Ephesus; and fear fell on them all, and the name of the Lord Jesus was magnified. And many that believed came, and confessed, and showed their deeds. Many of them also which used curious arts brought their books together, and burned them before all men: and they counted the price of them, and found it fifty thousand pieces of silver. So mightily grew the word of God and prevailed."
"After these things were ended, Paul purposed in the spirit, when he had passed through Macedonia and Achaia, to go to Jerusalem, saying, After I have been there, I must also see Rome. So he sent into Macedonia two of them that ministered unto him, Timotheus and Erastus; but he himself stayed in Asia for a season." (Acts 19:17-22 KJV)
Erastus is mentioned in the verse quote above with Timothy. In Paul's epistle to Timothy (see Epistles), Erastus is again mentioned.
"Salute Prisca and Aquila, and the household of Onesiphorus. Erastus abode at Corinth: but Trophimus have I left at Miletum sick. Do thy diligence to come before winter. Eubulus greeteth thee, and Pudens, and Linus, and Claudia, and all the brethren."
"The Lord Jesus Christ be with thy spirit. Grace be with you. Amen" (2 Timothy 4:19-22 KJV)
The reference to "Erastus abode at Corinth" in the verses above may be referring to the same Erastus of Corinth who was the chamberlain of the city. Either way, Erastus was a prominent Christian, or were two prominent Christians, of that time.
"And the God of peace shall bruise Satan under your feet shortly. The grace of our Lord Jesus Christ be with you. Amen. Timotheus my workfellow, and Lucius, and Jason, and Sosipater, my kinsmen, salute you."
"I Tertius, who wrote this epistle, salute you in the Lord."
"Gaius mine host, and of the whole church, saluteth you. Erastus the chamberlain of the city saluteth you, and Quartus a brother."
"The grace of our Lord Jesus Christ be with you all. Amen" (Romans 16:20-24 KJV)
