Theme: Jesus Christ has reconciled us to God in one body through the cross; listen to his words, love his people

On the day called Sunday there is a gathering together in the same place of all who live in a given city or rural district. The memoirs of the apostles or the writings of the prophets are read, as long as time permits. Then when the reader ceases, the president in a discourse admonishes and urges the imitation of these good things. Next we all rise together and send up prayers. When we cease from our prayer, bread is presented and wine and water. The president in the same manner sends up prayers and thanksgivings, according to his ability, and the people sing out their assent, saying the ‘Amen.’ A distribution and participation of the elements for which thanks have been given is made to each person, and to those who are not present they are sent by the deacons.
- Justin Martyr, First Apology, 67, ca. 150 A.D.
