Here you will find a compilation of the texts of Vatican II cited or mentioned in the book Paths of Love.
All the faithful, whatever their condition or state, are called by the Lord, each in his own way, to that perfect holiness whereby the Father Himself is perfect. (Lumen Gentium, ch. 2, n. 11)
Seminarians who according to the holy and firm laws of their own rite follow the venerable tradition of priestly celibacy, are to be carefully educated for this state, in which, renouncing conjugal union for the sake of the kingdom of heaven (cf. Mat. 19:12), they cling to God with an undivided love intimately in harmony with the new convinent, they offer witness of the future world of the resurrection, and obtain a most suitable aid for exercising continually that perfect charity, by which in the priestly ministry they may become all things for all people. Let them realize with a most grateful heart that this state should be undertaken not only as prescribed by the law of the Church, but is to be humbly begged for as a most precious give of God, to which they should strive to respond freely and generously, with the help and impulse of the grace of the Holy Spirit. They ought rightly to acknowledge the duties and dignity of Christian matrimony, which is a sign of the love between Christ and the Church (cf. Eph 5:22-33), yet recognize the surpassing excellence of virginity consecrated to Christ, so that with a deliberate, mature and magnanimous choice, they may devote themselves to God with a complete gift of body and spirit. (Optatam Totius, n. 10.)
