“It is evident that one who would merely aim at avoiding mortal sin would not be living according to the standard .of moral conduct outlined in the Gospel. Our Lord proposes to us as the ideal ot holiness the very perfection of Our Heavenly Father: "Be ye therefore perfect, as also your heavenly Father is perfect. " Hence, all having God for their Father must approach this divine perfection.... Fundamentally, the whole Sermon on the Mount is nothing but a commentary on and the development of this ideal. The path to follow is the path of renunciation, the path of imitation of Christ and of the love of God: "Any man come to me, and hate not" (that is to say does not renounce) "his father and mother and wife and children and brethren and sisters, yea and his own life also, he cannot be my disciple. " We are bound, then, on certain occasions to choose God and His will rather than the love of parents, of wife, of children, of self, and to sacrifice all to follow Christ. This suppose heroic courage, which will be found wanting in the time of need, unless God in His mercy give a special grace and unless one be prepared by sacrifices that are not of strict obligation.

“[O]ften men, deceived by the Evil One, have become vain in their reasonings and have exchanged the truth of God for a lie, serving the creature rather than the Creator. […] By the proclamation of the Gospel… [the Church] gives [non-Christians] the dispositions necessary for baptism, snatches them from the slavery of error and of idols and incorporates them in Christ…”

“Basing itself upon Sacred Scripture and Tradition, [this Council] teaches that the Church, now sojourning on earth as an exile, is necessary for salvation. Christ, present to us in His Body, which is the Church, is the one Mediator and the unique way of salvation. In explicit terms He Himself affirmed the necessity of faith and baptism and thereby affirmed also the necessity of the Church, for through baptism as through a door men enter the Church. Whosoever, therefore, knowing that the Catholic Church was made necessary by Christ, would refuse to enter or to remain in it, could not be saved.”
