It is especially in the sacred liturgy that our union
with the heavenly Church is best realized; in the liturgy, through the
sacramental signs, the power of the Holy Spirit acts on us, and with community
rejoicing we celebrate together the praise of the divine majesty, when all
those of every tribe and tongue and people and nation (cf. Apoc. 5:9) who
have been redeemed by the blood of Christ and gathered together into one Church
glorify, in one common song of praise, the one and triune God. When, then, we
celebrate the Eucharistic sacrifice we are most closely united to the worship
of the heavenly Church; when in the fellowship of communion we honor and
remember the glorious Mary ever virgin, St. Joseph, the holy apostles and
martyrs and all the saints. (Lumen gentium, 48)

'God is love, and he who abides in love abides in God,
and God abides in him' (1 Jn 4:16). God has poured out his love in our hearts
through the Holy Spirit who has been given to us (cf. Rom 5:5); therefore the
first and most necessary gift is charity, by which we love God above all things
and our neighbor because of him. But if charity is to grow and fructify in the
soul like a good seed, each of the faithful must willingly hear the word of God
and carry out his will with deeds, with the help of his grace; he must
frequently partake of the sacraments, chiefly the Eucharist, and take part in
the liturgy; he must constantly apply himself to prayer, self-denial, active
brotherly service and the practice of all virtues. This is because love, as the
bond of perfection and fullness of the law (cf. Col 3:14; Rom 13:10),
governs, gives meaning to, and perfects all the means of sanctification. Hence the true disciple of Christ is marked by love both of God and of his
neighbor. (Lumen Gentium, 42)
