I edited this article to clarify that the Eucharist is practiced in other denominations besides Roman Catholicism. I also changed the word "tradition" to "Sacrament". I'm not aware of any denominations that don't consider it a Sacrament, but if there are, let me know. Clarinetguy097 17:26, 16 April 2016 (EDT)
The Eucharist, or Communion, is a Sacrament that has been practiced since the beginning of the church. It was originally started by Jesus during the last supper. It involves eating bread and drinking wine, which are believed by Roman Catholics, Eastern Orthodox, and some Protestants to be Jesus's body and blood.
