"The celebration of the Eucharist . . . cannot be the starting-point for communion; it presupposes that communion already exists, a communion which it seeks to consolidate and bring to perfection."

"Eucharistiae celebratio . . . non potest esse principium communionis, quandoquidem illam iam veluti exsistentem praeponit, ut eam confirmet et ad perfectionem perducat."

     Pope John Paul II, Ecclesia de Eucharistia (17 April 2003) 35.
