What does the Church itself say about the Eucharist

"The Eucharist, although it is the fullness of sacramental life, is not a prize for the perfect but a powerful medicine and nourishment for the weak. These convictions have pastoral consequences that we are called to consider with prudence and boldness. Frequently, we act as arbiters of grace rather than its facilitators. But the Church is not a tollhouse; it is the house of the Father, where there is a place for everyone, with all their problems" (Evangelii Gaudium, 47).
