The Institution of the Eucharist is seen in all the gospel as well as Paul's first letter to the Corinthians. Although all the testimonies seem to be about the same there are subtle differences that hold different meanings. The first letter to the Corinthians was written during Paul's stay in Ephesus, 54-57 AD, probably in the spring of 57 AD. Corinth was located at the southern end of the narrow isthmus that joins the Peloponnesus to the Greek mainland. It was a happening city with a large population and a lot of corrupt action. Paul's first letter to the Corinthians was written in response to information delivered to him about the disorders in the Corinthian churches. Paul's letters to the Corinthians, especially the first, "permit us to gaze intimately on the exuberant life of one of the earliest urban communities" (Brown 1968). Without these letters, what we know of the spiritual movements during early Christianity as well as the problems that tried the apostles would be vague. The first letter to the Corinthians contains the earliest known testimony about the institution of the Eucharist. It was written eight years before Mark's gospel. This testimony probably represents the form used in the Antiochene liturgy; very similar to that of Luke's as we will see.

The gospel of Luke was probably written by a physician after 70 AD. He writes primarily for gentiles and for their sake he makes many changes in the Gospel tradition. Such as, omitting Semitic words or finding substitutions for them and seldom quoting the old testament. This gospel mov...
