[123] The community of goods may have evolved itself naturally enough out of the celebration of the Eucharist. Just let us realize what must have happened, say, on the day of Pentecost and the few succeeding days. The Apostles seem to have been living a common life during the ten days of expectation. They dwelt in the house where the upper room was. The day after Pentecost there must have been a great deal to do, in prayer, baptism, and celebration of the Eucharist. Their converts would join with them in the eucharistic feast, from day to day celebrated after the primitive fashion at the end of a common meal. Some enthusiast may then have suggested that, as the Master might at any moment appear, they should always live and eat in common. After a time, as the numbers increased, this arrangement had to be modified, and a daily distribution was substituted for daily common meals. The community of goods may thus have been developed out of the spiritual feast of the Eucharist, which they took in common. When the daily distribution terminated by the exhaustion of the funds, the Agape or lovefeast took its place, remaining as a fragment or relic of the earlier custom. Pliny in his letter mentions the Agape, and rightly distinguishes it from the worship of the Christians which was celebrated in the early morning. "After these ceremonies they used to disperse, and assemble again to share a common meal of innocent food." [124] In the twelfth century the number of cardinal deacons was fixed at fourteen, at which it has ever since remained.
