Who is involved in the cermony of eucharist and what do they do?

Answer 1

A validly Ordained Catholic Priest is the one who consecrates the Host and the faithful are the ones who receive Holy Communion.

Roman Catholic Answer:A valid Eucharist is with only a priest and a server, or even a priest alone, as the whole company of heaven is present at every Mass. But, normally, there would be a priest celebrating, at least one server, and the Faithful who are participating. The Eucharist in the Ordinary Form is comprised of a greeting, a penitential rite, an opening prayer, a reading, a psalm, a second reading on a Solemnity or a Sunday, followed by a Homily (sermon), intercessions. Then the priest moves to the altar, there is an Offering, the Preface, the Sanctus (Holy, Holy, Holy), and the Eucharistic Prayer (the Canon, in which the Priest, as Christ calls down the Holy Spirit confects the Eucharist); followed by the Our Father, the Peace, the Lamb of God, the preparation for Holy Communion, and the priest's Communion. Any faithful who are present may receive Holy Communion after the priest IF they are properly prepared and have been to Confession. Following there is a Thanksgiving, and a blessing.
