Andreas of Caesarea, on 1Pet 5:13

“The church that is in Babylon, elected together with you, saluteth you: and so doth my son Mark.”

“Peter calls Rome Babylon in a metaphorical sense. The woman who is chosen along with us is the church of Christ established in that city. He also mentions Mark the Evangelist, whom he calls his son in Christ and to whom he entrusted the task of writing the Gospel.”
