“So that the fullness of the sign may be made more clearly evident to the faithful in the course of the Eucharistic banquet, lay members of Christ’s faithful, too, are admitted to Communion under both kinds, in the cases set forth in the liturgical books, preceded and continually accompanied by proper catechesis regarding the dogmatic principles on this matter laid down by the Ecumenical Council of Trent”
The purpose, then, of receiving Holy Communion under both kinds, is not that the faithful receive more grace than when they receive it under one kind alone, but that the faithful are enabled to appreciate vividly the value of the sign. Sadly, this distinction has not always been made clear and some people, when not offered Holy Communion under both kinds, have expressed a sense of bewilderment, even thwarted entitlement, or a feeling that Holy Communion under one kind alone was, to some extent, deficient.
