On a Mission

“At the end of the Mass the deacon, or in his absence the priest, says to us 'Ite, Missa Est.' Our celebration is over. Go now to live and share with other people what we have received, heard, sung, meditated and prayed. The Mass sends us on mission.
The first duty which the Eucharistic celebration enjoins on us is to live the faith and share it with other people. Evangelization in the express form of proclamation of salvation in Jesus Christ is a priority. We must share with other people 'the supreme good of knowing Christ Jesus.' Every Catholic — priest, consecrated person or lay faithful — will do this according to that person's vocation and mission in the Church and in the world.
In the Eucharistic mystery our beloved Lord and Saviour Jesus Christ is giving us the inestimable gift of himself. He asks for our response. Shall we refuse to pay him back with love? May the Most Blessed Virgin Mary obtain for us the grace to respond with generosity, with constant faith, with heartfelt adoration and with apostolic dynamism.”
—Cardinal Arinze, Address at Westminster Cathedral, April 2006
