Priscilla and Aquila are one of the most beautiful ministry partnerships in the New Testament. We first meet them in Acts 18:2, when Paul arrived in Corinth and found them — Jewish refugees recently expelled from Rome by Claudius' edict against the Jews. Paul stayed and worked with them because, like Paul, they were tentmakers by trade. They eventually became believers (if they weren't already) and committed Christian workers. When Paul left Corinth for Ephesus, Priscilla and Aquila went with him. In Ephesus they met Apollos, a gifted but theologically incomplete preacher. "When Aquila and Priscilla heard him, they took him aside and explained to him the way of God more accurately" (Acts 18:26). Notice: Priscilla taught Apollos. No one in the early church seems to have had a problem with this, because it was private instruction of a fellow believer alongside her husband, not public teaching or eldership. They later hosted a house church (1 Corinthians 16:19, Romans 16:5) and Paul remembered them with deep affection: "Greet Priscilla and Aquila, my fellow workers in Christ Jesus, who risked their own necks for my life, to whom not only I give thanks, but also all the churches of the Gentiles" (Romans 16:3-4). Priscilla is named before Aquila in most references, which is unusual for the ancient world and may suggest she was the more theologically articulate of the two. They are a picture of marriage as ministry partnership: one couple, one Christ, one mission, risking their necks together.
Acts 18:2-3 — "And he found a certain Jew named Aquila, born in Pontus, who had recently come from Italy with his wife Priscilla... So, because he was of the same trade, he stayed with them and worked; for by occupation they were tentmakers."
Acts 18:26 — "So he began to speak boldly in the synagogue. When Aquila and Priscilla heard him, they took him aside and explained to him the way of God more accurately."
Romans 16:3-4 — "Greet Priscilla and Aquila, my fellow workers in Christ Jesus, who risked their own necks for my life, to whom not only I give thanks, but also all the churches of the Gentiles."
1 Corinthians 16:19 — "The churches of Asia greet you. Aquila and Priscilla greet you heartily in the Lord, with the church that is in their house."
