41 When Christian literature was still in its infancy, the unknown author of the work called the "Didache or Teaching of the Twelve Apostles" had this to write on the subject: "As far as the Eucharist is concerned, give thanks in this manner: . . . just as this bread had been broken and scattered over the hills and was made one when it was gathered together, so too may your church be gathered into your kingdom from the ends of the earth." (44)
