Origen, on 1Thess 1:1

“Paul and Sylvanus and Timothy: to the church of the Thessalonians, in God the Father, and in the Lord Jesus Christ.”

“Two made a symphony, Paul and Sosthenes, when writing the first epistle to the Corinthians. After this Paul and Timothy sang in harmony when they wrote their second letter to the same church. And even three made a symphony when Paul and Silvanus and Timothy gave instruction by letter to the Thessalonians.”
