“And on the day called Sunday there is a meeting in one place of those who live in cities or the country, and the memories of the apostles or the writings of the prophets are read as long as time permits. When the reader has finished, the president in a discourse urges and invites [us] to the imitation of these noble things.”

Justin Martyr, First Apology, LXVII

Written about 155 A.D.
