In his Post-synodal Apostolic Exhortation Sacramentum caritatis, “On the Eucharist as the Source and Summit of the Church’s Life and Mission,” Pope Benedict XVI recalls a passage from the Confessions of Saint Augustine, regarding the Holy Eucharist. Saint Augustine writes about the different effect of consuming the Heavenly Bread of the Holy Eucharist in comparison with the effect of eating earthly food. Earthly food is assimilated into our very being; it becomes a part of us.

In the Heart of Jesus, we find the refreshment and fortitude to become for our neighbor “a spring whose water never fails” (Is 58:11). In the words of Saint Paul, our Lord Jesus Christ gives us the grace to offer our bodies “as a living sacrifice, holy and acceptable to God, which is [our] spiritual worship” (Rom 12:1) (Pope Benedict XVI, Post-synodal Apostolic ExhortationSacramentum caritatis, “On the Eucharist as the Source and Summit of the Church’s Life and
