780. Summary of the Eleventh Article: “The resurrection of the body.”--The soul is immortal, the body mortal. But at the end of the world the bodies of all the dead, even though corrupted, shall be restored and reunited with their principle of life--i.e., the soul to which they belonged. Substantially, the risen body will be identical with the mortal body, but it will have certain new qualities corresponding to its new state. 781. Summary of the Twelfth Article: “Life everlasting.”--Those who die in the friendship of God will be received into unending happiness, in which they will be exempted from all evil and enjoy the beatific vision and other divine gifts. 782. The Acts of Faith.--According to St. Paul, there are two acts of faith, one internal, the other external: “With the heart we believe unto justice, but with the mouth confession is made unto salvation” (Rom., x. 10). (a) The internal act of faith is the firm and constant judgment of the intellect assenting to divine revelation (II Cor., x. 5), but freely and under the command of the will (Mark, xvi. 16), being moved thereto by divine grace (Eph., ii. 5). (b) The external act of faith is the profession before the world by signs, such as words or deeds, of the internal assent given to divine revelation. 783. The internal act of faith is one, but it has a threefold relationship: (a) it believes about God, if we consider the intellect as assenting to the material object; (b) it believes God, if we consider the intellect as assenting to the formal object; (c) it believes in God, if we consider the will as moving the intellect to assent, and tending towards God as the Last End. 784. The truths to which the assent of faith is given are either supernatural or natural. (a) Supernatural truths or mysteries (e.g., the Trinity of Persons in God) are revealed for faith, that man may know, desire and work for the supernatural destiny to which he has been raised. (b) Natural truths (e.g., the Oneness of God) are revealed for faith, so that mankind may obtain more quickly, more generally, and more certainly the knowledge of divine things which reason can afford. It is impossible, however, that an act of faith and an act of knowledge should coexist in the same individual about the same truth, for faith is of things that appear not. 785. The act of faith is a necessary preliminary to other supernatural acts, for we do not tend towards the supernatural, unless we first accept it by belief; hence, faith is necessary. But the act of faith may also be made after other supernatural acts, like those of hope and charity; and so it may be meritorious. (a) The act of faith is necessary, both as a means and as a precept (see 360). The necessity of means will be treated now, the necessity of precept later, when we speak of the commandments of faith (see 913 sqq.). (b) The act of faith before justification is meritorious congruously and in a wide sense; but after justification it has condign merit (see 110).
