Then Catholics who are in a state of grace approach the priest, deacon or extraordinary minister and are given a consecrated Host.Sometimes, they’re also offered a sip of the Precious Blood (the consecrated wine) from the cup.Before actually receiving Holy Communion, a Catholic makes some sign of reverence — a bow of the head, the sign of the cross, a genuflection, kneeling, and so on.When presenting the consecrated Host, the priest, deacon or extraordinary minister says “the Body of Christ” to which the recipient replies “Amen,” signifying, “Yes, I do believe it is Jesus.” If the Precious Blood is offered, the communicant may go to the person holding it who says, “the Blood of Christ,” and she replies again, “Amen.” Then she takes the cup and drinks a few sips of the consecrated wine and hands the cup back.The priest or deacon connects the Scripture readings to the daily lives of the people, the teachings of the Church, or the particular celebration at hand.On Sundays and holy days, the homily is followed by the Profession of Faith, or Creed, which succinctly sums up all the teachings of the Church.
Going to Mass is the only way a Catholic can fulfill the Third Commandment to keep holy the Sabbath day and the only regular opportunity to receive the Holy Eucharist.
Eastern Catholics also use the two-fold division of Liturgy of the Catechumens and Liturgy of the Faithful, which coincide with the Liturgy of the Word and the Liturgy of the Eucharist.
The differences are merely from the fact that in the West, the Mass follows the tradition of the Roman liturgy, but in the East, it’s the liturgical tradition of Constantinople.
It still looks, feels, and tastes like bread and wine, but it’s not.
The ringing of bells at the Consecration signifies the holiest moment of the Mass, a symbol of reverent rejoicing.
