“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
