§ 36.3. =The _Missa Fidelium_.=--The centre of this part of the service was the celebration of the Lord’s Supper. In the time of Justin Martyr the liturgy connected therewith was very simple. The brotherly kiss followed the common prayer, then the sacramental elements were brought in to the ministrant who consecrated them by the prayer of praise and thanksgiving (εὐχαριστία). The people answered Amen, and thereupon the consecrated elements were distributed to all those present. From that prayer the whole ordinance received the name εὐχαριστία, because its consecrating influence made common bread into the bread of the Supper. Much more elaborate is the liturgy in the 8th Book of the _Apostolic Constitutions_ (§ 43, 4), which may be regarded as a fair sample of the worship of the church toward the end of the 3rd century. At the close of the sermon during the prayers connected with that part of the service began the withdrawal successively of the Catechumens, the energumens and the penitents. Then the _Missa fidelium_ was commenced with the common intercessory prayer of the church. After various collects and responses there followed the brotherly kiss, exhortation against participation in unworthy pleasures, preparation of the sacramental elements, the sign of the cross, the consecration prayer, the words of institution, the elevation of the consecrated elements, all accompanied by suitable prayers, hymns, doxologies and responses. The bishop or presbyter distributed the bread with the words, Σῶμα Χριστοῦ; the deacon passed round the cup with the words, Αἷμα Χριστοῦ, ποτήριον ζωῆς. Finally the congregation kneeling received the blessing of the bishop, and the deacon dismissed them with the words, Ἀπολύεσθε ἐν εἰρήνῃ.--The bread was that commonly used, _i.e._, leavened bread (κοινὸς ἄρτος); the wine also was, according to the custom of time, mixed with water (κρᾶμα), in which Cyprian already fancied a symbol of the union of Christ and the church. In the African and Eastern churches, founding on John vi. 53, children, of course, those who had already been baptised, were allowed to partake of the communion. At the close of the service the deacons carried the consecrated sacramental elements to the sick and imprisoned. In many places a portion of the consecrated bread was taken home, that the family might use it at morning prayer for the consecration of the new day. No formal act of confession preceded the communion. The need of such an act in consequence of the existing disciplinary and liturgical ordinance had not yet made itself felt.
