Originally published in Italian by the Vatican Press, this book offers readers insights into the sacrality which ought to surround the distribution and reception of Holy Communion Relying on accurate history and good theology, the author makes a plea for a return to distributing the Eucharist to kneeling communicants on the tongue -- the practice now restored at papal liturgies by Pope Benedict XVI. The book comes with the endorsement of the two highest officials in the Vatican's Congregation for Divine Worship and the Discipline of the Sacraments.
