In order to believe, man needs the interior help of the Holy Spirit. The Church's faith precedes, engenders, supports, and nourishes our faith. The Church is the mother of all believers. No one can have God as Father who does not have the Church as Mother. We believe all that which is contained in the word of God, written or handed down, and which the Church proposes for belief as divinely revealed.
Faith is necessary for salvation.
Faith is a foretaste of the knowledge that will make us blessed in the life to come. But the real differences on this point are not so great that we cannot work with each other. On this matter too, evangelicals I know do not entirely agree with each other. How exactly this is accomplished is a mystery, the same mystery that makes the Church Christ's Body, and all Christians one in Christ, despite disagreements. The Catholic Church takes very serious the wounds to unity that are evident today, and seeks healing, but without compromising truth.
