On the day which is called Sunday we have a common assembly of all who live in the cities or in the outlying districts, and the memoirs of the Apostles or the writings of the Prophets are read, as long as there is time. Then, when the reader has finished, the president of the assembly verbally admonishes and invites all to imitate such examples of virtue. Then we all stand up together and offer up our prayers, and, as we said before, after we finish our prayers, bread and wine and water are presented. He who presides likewise offers up prayers and thanksgivings, to the best of his ability, and the people express their approval by saying ‘Amen.’ The Eucharistic elements are distributed and consumed by those present, and to those who are absent they are sent through the deacons.
Justin Martyr, The First Apology, Chapter 67.
What do you notice?
I notice that a large amount of this second century worship service was given to reading of the scriptures (gospels and OT). It wasn’t about preaching. The scriptures preached themselves and the president just exhorted folks to listen and obey.
Then prayer, then the Lord’s Supper.
Wouldn’t that be refreshing to do today?
