The Sacraments

  1. Recap:

    Chapter 1: Why study theology?

    - Theology is wisdom which is the knowledge of all things in relation to their highest cause.

    - Theology is the greatest of all sciences by the sublimity of its object: God; and by the certitude of its conclusions: the certitude of faith.

    - Theology teaches us our finality: the finality of man is the supernatural perfection of all his faculties - the greatest among these are his intellect and will.

    - Theology helps us attain our finality in respect of ourselves by the perfect love of God.

    - Theology helps us attain our finality in respect of our neighbour: if we love God, then we love everything He loves.

    Chapter 2: Spirit

    - A spirit is an immaterial intelligent living being (types: God, the angels and the souls of men)

    - A soul is defined as the first principle of life of those material things which live (plants, animals and men). Plants, animals and men have souls, but only the souls of men are spirits.

    - Properties: a spirit does not change in its being, does not corrupt, does not die (and is therefore eternal), has no mass, no shape, and no place e say that spirits are subsistent, which means that they have all they need to exist - they do not need a body to exist (like a plant or animal soul).

    Acts: to know and love. No material organ is required for these activities.

    Chapter 3: The Infinite Spirit

    God is the Infinite Spirit. 

    - God is all knowing, all loving, all powerful

    - God is His own existence

    - God was not created, He does not change, He has no past and future, God perpeturally in the present.

    - God is naturally everywhere: by His essence (per essentiam), by His power (per potentiam), by His knowing (per scientiam)

    God is Actus Purus, He cannot ever be in potency to doing anything; He is His action.  St. Thomas says that He is Actus Purus – one , simple, infinite and perfect action which is always in the present.

    Chapter 4: The Blessed Trinity

    The Blessed Trinity is the term used to express the central doctrine on the Christian religion: the truth that in the unity of the Godhead there are Three Persons, the Father, the Son and the Holy Ghost, these Three Persons being truly distinct from one another. There is one being, with one nature and there are Three Persons. The Blessed Trinity is known only by revelation, but can subsequently be explored by reason.

    Chapter 5: The Three Persons

    In an attempt to understand as much as possible about the Blessed Trinity using revelation and our knowledge of the intellect and being (by the science of metaphysics), St. Thomas, building on theologians before him, makes a best attempt to reconcile the unity of God and the distinction of the Three Persons in God. God has one nature by which the Three Persons operate. The distinction of the Three Persons is discerned in the mutually opposed relations resulting from the act of God knowing Himself and loving Himself. The Persons, are distinguished as the subsistant relations or Paternity, Filiation and Passive Spiration.

    Most of us, however, do not have a sufficient grasp of metaphysics to understand this complex theory and so a simpler one is proposed: In the act of knowing Himself, God generates a mental Word which is identical to the Generator. In the generator we discern the Father, in the generated, we discern the Son. These are Persons Who will naturally love each other, this love being personified in the Holy Ghost

    Chapter 6Making the doctrine of the Trinity a living and loved reality

    For most people something like that happens when they embrace a mystery of the faith revealed to them by the Church:

     - first there is an intellectual response as they grasp the theological exposition of the mystery

     - then a vital response as the wonder and beauty of the mystery draws the observer in

     - then a loving response as the mystery becomes a light and a power in our lives.

    Chapter 7: Creation

    God created all things from nothing and sustains all things in existence from moment to moment - all for His glory. 

    Chapter 8: The nature of man

    Man is made in the image and likeness of God, possessing an intellect and a will. He is different from the animals because he loves the things he knows whereas animals are attracted to the thing they sense; and he can choose what to love whereas animals are attracted to things by nature. Man is capable of moral good or evil, whereas animals always act according to their nature. The ultimate purpose of man is to know and love God. The ultimate purpose of non-intelligent creatures is to adorn creation for the glory of God.

    Chapter 9: The Supernatural Life

    Man is made for the Beatific Vision (that perfect possesion of God in heaven) but with his fallen nature he is radically incapable both of attaining this end and remaining in this state of perfect happiness. By sanctifying grace, man begins a supernatural life here below. He is transformed by grace and receives supernatural virtues and the Gift of the Holy Ghost with grace. He begins to live and act with the life and actions of God. He enters on to the path to heaven and progresses towards it. If he die in a state of grace, then the supernatural life within him is perfected to the point of perfect bliss in union with God.

    Chapter 10: The Fall

    Despite sanctifying grace, supernatural virtues, Gifts of the Holy Ghost, and the praternatural gifts, Adam fell for the temptation to become like God. This was the sin of pride. He was left bereft of everything supernatural and praeternatural, and therefore incapble of attaining that for which he was made: the Beatific Vision. The act against the injunction of God is called Original Sin, the consequence of this act (the deprivation of grace and gifts) is also called Original Sin. The Divine Will ordained that the Original Sin (consequence) be suffered by all the offspring of Adam. 

    Chapter 11: The Redeemer

    Jesus Christ is the Second Person of the Blessed Trinity Who operates through a divine nature as God, and through a human nature as man. The two natures are hypostatically united in the Person which allow him to act as a man but with acts of infinite value because His Person is divine. By taking to himself his human nature at the Incarnation, Jesus Christ was able to redeem mankind.

    Chapter 12: The Redemption

    The Redemption is the (a) freeing of man from the debt (in justice to God) of sin, and (b) the restoration of man's supernatural union with God. Our Lord Jesus Christ objectively redeemed all mankind by His Incarnation, Life, Passion & Death, Resurrection and Ascension into heaven. It is for man to participate in this act of redemption by living a life of faith, hope and charity through the means that the Church provides (teaching, laws and liturgy). Such a life constitutes mans subjective redemption.

    Chapter 13: The Visible Church

    The visible Church is a hierarchy of baptised souls united under one head (Jesus Christ) who adhere to the teaching of the Church, submit to the authority of the Church, and worship God with the liturgy of the Church. Members of the visible Church may be living members (when they are in a state of sanctifying grace) or dead members (when they are in mortal sin).

    Chapter 14: The Mystical Body of Christ

    The Church binds chosen men and angels together into one body, but unlike any other union in the universe, the reason of unity is above the order of nature, and immeasurably more intimate - it is the unity of living the same Life. Every living member of the Church lives by participating in the Divine Life (by sanctifying grace). Inevitable with this unity of Life, there is a unity of love and obedience and intention, but these are consequences rather than causes of unity. The unity by grace is called the Mystical Body of Christ.

    Chapter 15: The Mother of God

    Mary is called the Mother of God because she is the mother of Jesus Christ according to His human nature. Jesus Christ is God, therefore, Mary is the Mother of God. For this reason she was preserved from Original Sin at her conception, preserved from corruption at the end of her earthly life, and assumed body and soul into heaven. She is given the title of Co-Redemptorix on account of the closeness of her participation in the act of Redemption; she is called Mediatrix of all grace on account of her divine motherhood and her uniquely privilged role as intercessor with her Son.

    Chapter 16.1 Grace, virtues and gifts

    To share in God's perfection, to be inclined towards God, and to know & love God, we must become co-natural with God so that we share in His being, powers, and actions. We share in His being by sanctifying grace; we share in his power by supernaturalised faculties; and we share in His actions by acts of supernatural virtue or acts impelled by the Gifts of the Holy Ghost.

    Chapter 16.2 How Grace is lost.

    The supernatural life of grace is lost by Original Sin and Mortal Sin. Sin is an offence against God by any thought, word, deed, or omission against the law of God. Sin may be Original Sin or Actual Sin. Original Sin as an act was committed by Adam, but in its effects (absence of grace & praeternatural gifts, wounded human nature) it affects every man at the moment of conception (except the Blessed Virgin Mary). Actual sin is an act committed by any man. Actual sin may be Mortal Sin of Venial Sin. A Mortal Sin is an act of total rebellion against God (like declaring war against a state). A Venial Sin is breaking a law of God without breaking allegiance to God (like breaking the speed limit of a state).

    Chapter 16.3 Conscience

    Conscience is the intellect’s determination of how to act in light of its knowledge of general moral principles, whether applied consciously or just as a matter of habit. It is not an emotion. Neither is it a perception or a special faculty. It is just an act of the intellect. We should always follow a true conscience and an invincibly ignorant erroneous conscience. We should not follow an otherwise erroneous conscience (vincibly ignorant, scrupulous, perplex, lax or pharasaical).

    Chapter 17 The Sacraments

    Definition: Q249. A sacrament is an outward sign of inward grace ordained by Jesus Christ, by which grace is given to our souls. Overview. Detail 

  2. Definitions

    The Sacrament of the Holy Eucharist: That Sacrament, in which Christ, under the forms of bread and wine, is truly present, with his Body and Blood, in order to offer Himself in an unbloody manner to the Heavenly Father, and to give Himself to the faithful as a nourishment for souls.

    The Holy Sacrifice of the Mass: The Holy Sacrifice of the Mass is the sacrifice of the Body and Blood of Jesus Christ, really present on the altar under the appearances of bread and wine, and offered to God for the living and the dead.

    Transubstantiation:  The change of the substance of the bread into the substance of our Lord's Body a change without parallel we call Transubstantiation , but meaning just what we have said. It is the only possible explanation of the Real Presence

    Sacramentum tantum: bread and wine and words of consecration (signum ut significans)

    Res et sacramentum: Body & Blood of Christ (significata ut significans)

    Res tantum: union with the Mystical Body by grace (effect)

  3. Effects of the Eucharist as offered and as received

    What Our Lord was giving us was a union with Himself closer than the Apostles had in the three years of their companionship, than Mary Magdalen had when she clung to Him after His resurrection. It was a supernatural participation in Him - in His being. It was also a participation in His act - that of the Divine Sacrifice - the act of Our Lord, so that it became our supreme and infinite act of adoration, thanksgiving, reparation and supplication.

  5. The Eucharist and the Mass

  6. Multipresence of Christ

    Christ's body is present in external extension (circumscriptive) only in heaven but is sacramentally present in the Eucharistic species wherever it may be. St. Thomas points out that circumscriptive multilocation is against reason (ie. Christ is not in each host in the same way as he is in His physical body in heaven - His mode of presence is sacramental.
