Justin Martyr said...

"We lead him who believes and is joined to us, after we have thus baptized him, to those who are called the brethren, where they gather together to say prayers in common for ourselves, and for him who has been enlightened, and for all who are everywhere. . . . We greet each other with a kiss when the prayers are finished. Then bread and a cup of water and wine are brought to the president of the brethren, and he having received them sends up praise and glory to the Father of all through the name of his Son and the Holy Ghost, and makes a long thanksgiving that we have been made worthy of these things by him; when these prayers and thanksgivings are ended all the people present cry 'Amen'. . . . And when the president has given thanks (eucharistesantos, already a technical name for the Eucharist) and all the people have answered, those whom we call deacons give the bread and wine and water for which the 'thanksgiving' (Eucharist) has been made to be tasted by those who are present, and they carry them to those that are absent.

This food is called by us the Eucharist" (the well-known passage about the Real Presence follows, with the quotation of the words of Institution).

On the day which is called that of the Sun a reunion is made of all those who dwell in the cities and fields; and the commentaries of the Apostles and writings of the prophets are read as long as time allows. Then, when the reader has done, the president admonishes us in a speech and excites us to copy these glorious things. Then we all rise and say prayers and, as we have said above, when we have done praying bread is brought up and wine and water; and the president sends up prayers with thanksgiving for the men, and the people acclaim, saying 'Amen', and a share of the Eucharist is given to each and is sent to those absent by the deacons.
