“The Eucharist is the source of the Christian life because whoever shares in it receives the motivation and strength to live as a true Christian. Christ’s sacrifice on the cross imparts to the believer the dynamism of his generous love. The Eucharistic banquet nourishes the faithful with the Body and Blood of the divine Lamb sacrificed for us and it gives them the strength to ‘follow in his footsteps’ (cf. 1 Pet 2:21).”
