The distribution of the Holy Communion during Mass is like an act of a lover meeting with the beloved. When we receive the Eucharist, we are welcoming Christ into our hearts and so it is an important moment. The priest and Deacon are the ordinary Ministers of the Eucharist and Lay Eucharistic Ministers are the Extraordinary Ministers of the Eucharist, authorized by the Church-authorities. Some have scrupulous thought that it is better to receive the Body of Christ only from the priest or deacon. Such people must believe that the Lay Eucharistic Ministers distribute the same Body of Christ as the Priest or Deacon.
At the end of the distribution of the Holy Communion, the remaining Consecrated Hosts are taken to the Tabernacle for private adoration and for the use of the sick and the homebound, who are unable to participate in the Mass with the community. After receiving the Communion, there is a time for meditation whether silent or singing a song.
Is it right to leave the Church immediately after receiving Communion? It is not right. Some people receive Communion and go straight to the parking lot. If someone would leave the party, before saying goodbye to the host and the fellow guests, would this be appreciated? I am sure it won’t be appreciated; rather it would distress the host. Just so would such people distress God, who has provided the spiritual meal.
After the concluding prayer, the priest concludes the Mass with the prayer and the final blessing in the name of the Father, Son, and the Holy Spirit. At this point, the priest or the deacon greets the people that the Mass is ended and the assembly may go in peace. With the response, “Thanks be to God”, the assembly goes out singing joyfully, empowered to serve in the outer world.
