The Eucharist remembrance of Jesus was not added into the gospels and probably wasn't practiced until after sacrifices at the Temple ended, roughly in 70 AD. The disciples were not remembering Jesus via Communion until years after the death of James who would not have chosen to remember Jesus via the body and blood metaphor of communion because(?) it was against his religion. (The video explains how Communion is such an anti-Semitic ritual.)
Second, the body and blood metaphor would not have been part of the Son of Man kingdom had Jesus sat on the Son of Man's earthly throne as he originally said he would do. The body and blood metaphor is a saving face practice. Jesus saw that he was going to be captured (with the help of Judas) for crucifixion before he sat on the Son of Man's throne; so, he did something that would turn the Hebrew God's face away from him and his disciples--leaving Judaism to form a new religion. THIS may be a Nazarene loosing his religion in 30 or 33 Common Era, but it's more likely post-Temple Christianity with this Lord's Last Supper being added when the gospels were written, after the Jewish Revolt began--and three of the gospels were not written until after the Temple was destroyed.
The body and blood metaphor of communion was not part of the Jerusalem church.
If the new covenant of Jesus' blood was in effect from when Jesus announced it going forward, then the meaning of the Temple of Jerusalem, a place to make animal sacrifices would be of less or no importance to the first generation Jerusalem Church.
The 11 disciples continued to meet at the Temple (at Solomon's Gate, I believe) and they did not help the Hellenists when their leader Stephen was attacked for speaking against the importance of the Temple. If the 11 disciples knew and understood that Jesus' new covenant of cannibalistic blood replaced the blood of animals sacrificed to the Hebrew God at the Temple shows, it is unlikely that the Temple would be a necessary place to meet and it is unlikely that they would have been so undefending of Stephen being martyred.
