Fasting Chapter 8 suggests that fasts are not to be on Monday and Thursday "with the hypocrites" - presumably non-Christian Jews - but on Wednesday and Friday. Nor must Christians pray with their Judaic brethren, instead they shall say the Lord's Prayer three times a day. The text of the prayer is not identical to the version in the Gospel of Matthew, and it is given with the doxology "for Thine is the power and the glory for ever." The Didache is the main source for the inclusion of the doxology. It does not occur within the oldest copies of the texts of Matthew and Luke. Most biblical scholars agree that it was included as a result of a later edit.
Eucharist Chapter 9 concerns the Eucharist ("thanksgiving"): "Now concerning the Eucharist, give thanks this way. First, concerning the cup: We thank You, our Father, for the holy vine of David Your servant, which You made known to us through Jesus Your Servant; to You be the glory for ever. And concerning the broken bread: We thank you, our Father, for the life and knowledge which You made known to us through Jesus Your Servant; to You be the glory for ever. Even as this broken bread was scattered over the hills, and was gathered together and became one, so let Your Church be gathered together from the ends of the earth into Your kingdom; for Thine is the glory and the power through Jesus Christ for ever.. But let no one eat or drink of your Eucharist, unless they have been baptized into the name of the Lord; for concerning this also the Lord has said, "Give not what is holy to the dogs." (Roberts) The Didache basically describes the same ritual as the one that took place in Corinth. The order of cup and bread differs both from present-day Christian practice and from that in the New Testament accounts of the Last Supper, of which, again unlike almost all presentday Eucharistic celebrations, the Didache makes no mention. Revelation 22:17 (KJV), to which the prayer in Didache 10 bears some similarity.
