Deepertruth: Eucharistic Miracles: The Didache and the Eucharist

The Early Christians Believed in the Real Presence. 

 "So then, brethren, stand firm and hold to the traditions which you were taught by us, either by word of mouth or by letter." (2 Thes. 2:15) "And what you have heard from me before many witnesses entrust to faithful men who will be able to teach others also." (2 Tim. 2:2) Many Catholics and non-Catholics alike think that the Roman Catholic Church invented the doctrine of transubstantiation.

Transubstantiation means that the bread and wine presented on the altar at the Mass become the the Body and Blood of Christ by the power of the Holy Spirit at the consecration.

The consecration is the time when the priest calls upon the Holy Spirit to change the bread and wine into Christ's Body and Blood. However, the Body and Blood retain the appearance of bread and wine.

The Roman Catholic Church, that is, the Latin Rite Catholic Church, and other Catholic Churches in communion with Rome believe that the Eucharist is the Real Presence of Jesus Christ, body, blood, soul and divinity.

The Orthodox Churches and most other Churches of the East do so as well. Anglican [Episcopalian] and other Protestant denominations have interpreted Christ's presence at the celebration of the Lord's Supper or Eucharist to be either only spiritual, or symbolic, or non-existent.
