And your "the early church had many meals together’. . . I daresay that from Monday-Saturday there were communal means. . . But not the liturgy/Eucharist on Sundays.
Read a bit of your history…
“The agape was thus related to the Eucharist as Christ’s last Passover [was] to the Christian rite which he grafted upon it. It preceded and led up to the Eucharist, and was quite distinct from it.” [vol. 1, p. 66] The Encyclopedia of Early Christianity, which represents both catholic and Protestant views, says this about the love feast: “In the history of early Christian practice, however, agape is also a liturgical term. Translated “love-feast” (Jude 12), it springs from the meal that the New Testament variously calls the “breaking of bread” (Acts 2:42-47; 20:7-12) and “Eucharist” (1 Cor. 11:20-34). A core tradition in the early church, the meal explicitly recalls the meals Jesus celebrated with his disciples, especially the Last Supper … and the post-resurrection meals recounted in Luke 24 and John 20-21.” [p. 17]”
In Justin Martyr, the Eucharist seems to have absorbed the fraternal functions characteristic of agape. …On the other hand, in Clement’s Alexandria (ca. 200) agape and Eucharist are joined, in spite of the signal abuses to which Clement gives witness.
“There is general agreement that from the mid-third century, agape and Eucharist go their separate ways.” [p. 17]
Nevertheless, even though the agape and communion went their separate ways, the church continued to practice both of them until some time after the time of Constantine. Perhaps the love feast would have continued on down to our times if the original apostolic pattern (holding the love feast and the Eucharist together) had not been broken. The International Standard Bible Encyclopedia makes this observation on the separation of the agape and Eucharist, and the eventual extinguishment of the agape:
In the Didache (ca. A.D. 100) there is no sign as yet of any separation. The direction that the second Eucharistic prayer should be offered “after being filled” appears to imply that a regular meal had immediately preceded the observance of the sacrament. In the Ignatian epistles (ca. A.D. 110), the Lord’s Supper and the agape are still found in combination… "
