What the Catechism of the Catholic Church says on "Once Saved, Always Saved:"

161. "Believing in Jesus Christ and in the One who sent him for our salvation is necessary for obtaining that salvation. [Cf. Mk 16:16 ; Jn 3:36 ; Jn 6:40 ; et al.] 'Since 'without faith it is impossible to please (God)' and to attain to the fellowship of his sons, therefore without faith no one has ever attained justification, nor will anyone obtain eternal life 'But he who endures to the end.'']"

162. "Faith is an entirely free gift that God makes to man. We can lose this priceless gift, as St. Paul indicated to St. Timothy: 'Wage the good warfare, holding faith and a good conscience. By rejecting conscience, certain persons have made shipwreck of their faith.' [1 Tim 1:18-19 .] To live, grow and persevere in the faith until the end we must nourish it with the word of God; we must beg the Lord to increase our faith; [Cf. Mk 9:24 ; Lk 17:5 ; Lk 22:32.] it must be 'working through charity,' abounding in hope, and rooted in the faith of the Church. [Gal 5:6 ; Rom 15:13 ; cf. Jam 2:14-26.]"
