The Public Reading of Christian Books
The public reading of Christian books took place for the most part in assemblies for worship. Justin Martyr, describing the procedure of Christian assemblies in the middle of the second century, says:
And on the day which is called the day of the sun there is an assembly of all those who live in the towns or in the country, and the memoirs of the apostles or the writings of the prophets are read for as long as time permits. Then the reader ceases, and the president speaks, admonishing and exhorting us to imitate these excellent examples. Then we all rise together and pray and, as we said before, when we have completed our prayer, bread is brought, and wine and water, and the president in like manner offers prayers and thanksgivings according to his ability and the people assent with Amen; and there is a distribution and partaking by all of that over which thanks have been given, and to those who are absent a portion is sent by the deacons. And those who collected is deposited with the president, who gives aid to orphans and widows and those who are in want on account of illness or any other cause, and to those also who are in prison and to strangers from abroad, and, in a word, cares for all who are in need (Apol. 1.67).
The reading mentioned here as a vital part of weekly assembly was by that time an established and probably universal Christian liturgical custom.

Now there are also many other things that Jesus did. Were every one of them to be written, I suppose that the world itself could not contain the books that would be written. John 21:25 (ESV)
