Here is a description I discovered this week of an early Christian sacrament meeting:
And on the day called Sunday, all who live in cities or in the country gather together to one place, and the memoirs of the apostles or the writings of the prophets are read, as long as time permits; then, when the reader has ceased, the president verbally instructs, and exhorts to the imitation of these good things. Then we all rise together and pray, and, as we before said, when our prayer is ended, bread and wine and water are brought, and the president in like manner offers prayers and thanksgiving, according to his ability, and the people assent, saying Amen; and there is a distribution to each, and a participation of that over which thanks have been given, and to those who are absent a portion is sent by the deacons.
Justin Martyr, First Apology, written A.D. 147-161
I feel a kinship with the early church when I read this. It is a precious gift to be able to participate in sacrament meetings in the Restored Church of Jesus Christ.
