"I would like to add a word about the Eucharist. In order to grow in our Christian life, we need to be nourished by the Body and Blood of Christ. In fact, we are baptized and confirmed with a view to the Eucharist as the "Source and summit" of the Church's life, the Eucharist is a "perpetual Pentacost" since every time we celebrate Mass we receive the Holy Spirit who unites us more deeply with Christ and transforms us into Him.
My dear young friends, if you take part frequently in the Eucharistic celebration, if you dedicate some of your time to adoration of the Blessed Sacrament, the Source of love which is the Eucharist, you will acquire that joyful determination to dedicate your lives to following the Gospel.
At the same time it will be your experience that whenever our strength is not enough, it is the Holy Spirit who transforms us, filling us with his strength and making us witnesses suffused by the missionary fervor of the risen Christ."
