Ecclesia de Eucharistia §26

²⁶ If, as I have said, the Eucharist builds the Church and the Church makes the Eucharist, it follows that there is a profound relationship between the two, so much so that we can apply to the Eucharistic mystery the very words with which, in the Nicene-Constantinopolitan Creed, we profess the Church to be “one, holy, catholic and apostolic”. The Eucharist too is one and catholic. It is also holy, indeed, the Most Holy Sacrament. But it is above all its apostolicity that we must now consider.
