Chapter I-4. Eucharist and Charity
5. Before proceeding to more detailed observations on the subject of the celebration of the holy Sacrifice, I wish briefly to
reaffirm the fact that eucharistic worship constitutes the soul of all Christian life. In fact, Christian life is expressed in the fulfilling
of the greatest commandment, that is to say, in the love of God and neighbor, and this love finds its source in the Blessed
Sacrament, which is commonly called the sacrament of love.
The Eucharist signifies this charity, and therefore recalls it, makes it present and at the same time brings it about. Every time that
we consciously share in it, there opens in our souls a real dimension of that unfathomable love that includes everything that God
has done and continues to do for us human beings, as Christ says: "My Father goes on working, and so do I." Together
with this unfathomable and free gift, which is charity revealed in its fullest degree in the saving sacrifice of the Son of God, the
sacrifice of which the Eucharist is the indelible sign, there also springs up within us a lively response of love. We not only know
love; we ourselves begin to love. We enter, so to speak, upon the path of love and along this path make progress. Thanks to
the Eucharist, the love that springs up within us from the Eucharist develops in us, becomes deeper and grows stronger.
Eucharistic worship is therefore precisely the expression of that love which is the authentic and deepest characteristic of the
Christian vocation. This worship springs from the love and serves the love to which we are all called in Jesus Christ. A
living fruit of this worship is the perfecting of the image of God that we bear within us, an image that corresponds to the one that
Christ has revealed in us. As we thus become adorers of the Father "in spirit and truth," we mature in an ever fuller union
with Christ, we are ever more united to Him, and--if one may use the expression--we are ever more in harmony with Him.
The doctrine of the Eucharist, sign of unity and bond of charity, taught by St. Paul, has been in subsequent times deepened
by the writings of very many saints who are living examples for us of Eucharistic worship. We must always have this reality
before our eyes, and at the same time we must continually try to bring it about that our own generation too may add new
examples to those marvelous examples of the past, new examples no less living and eloquent, that will reflect the age to which
