This is what the Church means when she speaks of the “Real Presence” of Christ in the Eucharist.

The Institution of the Eucharist is written down in the four Gospels below:
The document The Mystery of the Eucharist in the Life of the Church was developed by the Committee on Doctrine of the United States Conference of Catholic Bishops (USCCB). It was approved by the full body of the USCCB at its November 2021 General Meeting and has been authorized for publication.
