Roman Catechism 18.146

Chapter 18 — Part II: The Sacraments — The Holy Eucharist

Section 146. It will therefore be the duty of the pastor frequently to admonish the faithful that, as they deem it necessary to afford daily nutriment to the body, they should also feel solicitous to feed and nourish the soul every day with this heavenly food. It is clear that the soul stands not less in need of spiritual, than the body of corporal food. Here it will be found most useful to recall the inestimable and divine advantages which, as we have already shown, flow from sacramental Communion. It will be well also to refer to the manna, which was a figure (of this Sacrament), and which refreshed the bodily powers every day. The Fathers who earnestly recommended the frequent reception of this Sacrament may also be cited. The words of St. Augustine, Thou sinnest daily, receive daily, express not his opinion only, but that of all the Fathers who have written on the subject, as anyone may easily discover who will carefully read them.
