Cappadocia first appears in the New Testament in Acts 2:9. Jews or Jewish converts from Cappadocia were among the international gathering in Jerusalem at Pentecost and witnessed the outpouring of the Holy Spirit and Peter's proclamation concerning Jesus.
Its second explicit New Testament appearance is in 1 Peter 1:1, where Christians in Pontus, Galatia, Cappadocia, Asia, and Bithynia are included among the recipients of the letter.
These references demonstrate that Jewish communities and, subsequently, Christian congregations were present within the interior regions of Asia Minor during the first century.
