The real presence of Christ in the Eucharist is the Christian doctrine that Jesus Christ is present in the Eucharist, not merely symbolically or metaphorically, but in a true, real and substantial way. There are a number of Christian denominations that teach that Christ is truly present in the Eucharist, including Catholicism, Eastern Orthodoxy, Oriental Orthodoxy, the Church of the East, the Moravian Church, Lutheranism, Anglicanism, Methodism, Irvingism and Reformed Christianity.

Writing to the Christians of Smyrna in the same year, he warned them to "stand aloof from such heretics", because, among other reasons, "they abstain from the Eucharist and from prayer, because they confess not the Eucharist to be the flesh of our Saviour Jesus Christ, which suffered for our sins, and which the Father, of His goodness, raised up again." In about 150, Justin Martyr, referring to the Eucharist, wrote: "Not
