In religion, faith has several aspects. Catholic doctrine calls faith the assent of the mind to truths revealed by God, the assent being made with the help of grace and by command of the will on account of the authority and trustworthiness of God revealing.
Faith is necessary for salvation.
The Catholic doctrine is that belief must be professed in the divinely revealed truths in the Bible and tradition as interpreted and proposed by the infallible teaching authority of the Church. Persons who are advanced in age or suffer from infirmity or illness, together with those who care for them, can receive Holy Communion even if they have not abstained from food and drink for an hour. A priest celebrating two or three Masses on the same day can eat and drink something before the second or third Mass without regard for the hour limit. A title of priests, who are regarded as spiritual fathers because they are the ordinary ministers of baptism, by which persons are born to supernatural life, and because of their pastoral service to people. A mental state caused by the apprehension of present or future danger.
