On the day we call the day of the sun,
all who dwell in the city or country gather in the same place.
The memoirs of the apostles and the writings of the prophets are read,
as much as time permits.
When the reader has finished,
he who presides over those gathered admonishes and challenges them
to imitate these beautiful things.
Then we all rise together and offer prayers for ourselves...
and for all others, wherever they may be,
so that we may be found righteous by our life and actions,
and faithful to the commandments,
so as to obtain eternal salvation.
When the prayers are concluded we exchange the kiss.
Then someone brings bread
and a cup of water and wine mixed together
to him who presides over the brethren. He takes them and offers praise and glory
to the Father of the universe, through the name of the Son
and of the Holy Spirit and for a considerable time he gives thanks
that we have been judged worthy of these gifts.
When he has concluded the prayers and thanksgivings,
all present give voice to an acclamation by saying:
When he who presides has given thanks
and the people have responded,
those whom we call deacons give to those present the
wine and water
and take them to those who are absent.
