Catechism of the Council of Trent: I believe in God the Father Almighty, Creator of heaven and earth
As God is called Father for more reasons than one, we must first determine the more appropriate sense in which the word is used in the present instance.
God Is Called Father Because He Is Creator And Ruler
Even some on whose darkness the light of faith never shone conceived God to be an eternal substance from whom all things have their beginning, and by whose Providence they are governed and preserved in their order and state of existence. Since, therefore, he to whom a family owes its origin and by whose wisdom derived from human things these persons gave the name Father to God, whom they acknowledge to be the Creator and Governor of the universe. The Sacred Scriptures also, when they wish to show that to God must be ascribed the creation of all things, supreme power and admirable Providence, make use of the same name. Thus we read: Is not he thy Father, that hath possessed thee, and made thee and created thee? And: Have we not all one Father? hath not one God created us?
God Is Called Father Because He Adopts Christians Through Grace
But God, particularly in the New Testament, is much more frequently, and in some sense peculiarly, called the Father of Christians, who have not received the spirit of bondage again in fear; but have received the spirit of adoption of sons (of God), whereby they cry: Abba (Father). For the Father hath bestowed upon us that manner of charity that we should be called, and be the sons of God, and if sons, heirs also; heirs indeed of God, and joint-heirs with Christ, who is the first-born amongst many brethren, and is not ashamed to call us brethren. Whether, therefore, we look to the common title of creation and Providence, or to the special one of spiritual adoption, rightly do the faithful profess their belief that God is their Father.
The Name Father Also Discloses The Plurality Of Persons In God
But the pastor should teach that on hearing the word Father, besides the ideas already unfolded, the mind should rise to more exalted mysteries. Under the name Father, the divine oracles begin to unveil to us a mysterious truth which is more abstruse and more deeply hidden in that inaccessible light in which God dwells, and which human reason and understanding could not attain to, nor even conjecture to exist.
This name implies that in the one Essence of the Godhead is proposed to our belief, not only one Person, but a distinction of persons; for in one Divine Nature there are Three Persons—the Father, begotten of none; the Son, begotten of the Father before all ages; the Holy Ghost, proceeding from the Father and the Son likewise, from all eternity.
The Doctrine Of The Trinity
In the one Substance of the Divinity the Father is the First Person, who with His Only-begotten Son, and the Holy Ghost, is one God and one Lord, not in the singularity of one Person, but in the trinity of one Substance. These Three Persons, since it would be impiety to assert that they are unlike or unequal in any thing, are understood to be distinct only in their respective properties. For the Father is unbegotten, the Son begotten of the Father, and the Holy Ghost proceeds from both. Thus we acknowledge the Essence and the Substance of the Three Persons to be the same in such wise that we believe that in confessing the true and eternal God we are piously and religiously to adore distinction in the Persons, unity in the Essence, and equality in the Trinity.
Hence, when we say that the Father is the First Person, we are not to be understood to mean that in the Trinity there is anything first or last, greater or less. Let none of the faithful be guilty of such impiety, for the Christian religion proclaims the same eternity, the same majesty of glory in the Three Persons. But since the Father is the Beginning without a beginning, we truly and unhesitatingly affirm that He is the First Person, and as He is distinct from the Others by His peculiar relation of paternity, so of Him alone is it true that He begot the Son from eternity. For when in the Creed we pronounce together the words God and Father, it means that He was always both God and Father.
Practical Admonitions Concerning The Mystery Of The Trinity
Since nowhere is a too curious inquiry more dangerous, or error more fatal, than in the knowledge and exposition of this, the most profound and difficult of mysteries, let the pastor teach that the terms nature and person used to express this mystery should be most scrupulously retained; and let the faithful know that unity belongs to essence, and distinction to persons.
But these are truths which should not be made the subject of too subtle investigation, when we recollect that he who is a searcher of majesty shall be overwhelmed by glory. We should be satisfied with the assurance and certitude which faith gives us that we have been taught these truths by God Himself, to doubt whose word is the extreme of folly and misery. He has said: Teach ye all nations, baptising them in the name of the Father, and of the Son, and of the Holy Ghost; and again, there are three who give testimony in heaven, the Father, the Word, and the Holy Ghost; and these three are one.
Let him, however, who by the divine bounty believes these truths, constantly beseech and implore God and the Father, who made all things out of nothing, and ordereth all things sweetly, who gave us power to become the sons of God, and who made known to the human mind the mystery of the Trinity—let him, I say, pray unceasingly that, admitted one day into the eternal tabernacles, he may be worthy to see how great is the fecundity of the Father, who contemplating and understanding Himself, begot the Son like and equal to Himself, how a love of charity in both, entirely the same and equal, which is the Holy Ghost, proceeding from the Father and the Son, connects the begetter and the begotten by an eternal and indissoluble bond; and that thus the Essence of the Trinity is one and the distinction of the Three Persons perfect.
"Almighty"
The Sacred Scriptures, in order to mark the piety and devotion with which the most holy name of God is to be adored, usually express His supreme power and infinite majesty in a variety of ways; but the pastor should, first of all, teach that almighty power is most frequently attributed to Him. Thus He says of Himself: I am the almighty Lord and again, Jacob when sending his sons to Joseph thus prayed for them: May my almighty God make him favourable to you. In the Apocalypse also it is written: The Lord God, who is, and who was, and who is to come, the almighty; and in another place the last day is called the great day of the almighty God. Sometimes the same attribute is expressed in many words; thus: No word shall be impossible with God; Is the hand of the Lord unable? Thy power is at hand when thou wilt, and so on.
Meaning Of The Term "Almighty"
From these various modes of expression it is clearly perceived what is comprehended under this single word almighty. By it we understand that there neither exists nor can be conceived in thought or imagination anything which God cannot do. For not only can He annihilate all created things, and in a moment summon from nothing into existence many other worlds, an exercise of power which, however great, comes in some degree within our comprehension; but He can do many things still greater, of which the human mind can form no conception.
But though God can do all things, yet He cannot lie, or deceive, or be deceived; He cannot sin, or cease to exist, or be ignorant of anything. These defects are compatible with those beings only whose actions are imperfect; but God, whose acts are always most perfect, is said to be incapable of such things, simply because the capability of doing them implies weakness, not the supreme and infinite power over all things which God possesses. Thus we so believe God to be omnipotent that we exclude from Him entirely all that is not intimately connected and consistent with the perfection of His nature.
Why Omnipotence Alone Is Mentioned In The Creed
The pastor should point out the propriety and wisdom of having omitted all other names of God in the Creed, and of having proposed to us only that of almighty as the object of our belief. For by acknowledging God to be omnipotent, we also of necessity acknowledge Him to be omniscient, and to hold all things in subjection to His supreme authority and dominion. When we do not doubt that He is omnipotent, we must be also convinced of everything else regarding Him, the absence of which would render His omnipotence altogether unintelligible.
Besides, nothing tends more to confirm our faith and animate our hope than a deep conviction that all things are possible to God; for whatever may be afterwards proposed as an object of faith, however great, however wonderful, however raised above the natural order, is easily and without hesitation believed, once the mind has grasped the knowledge of the omnipotence of God. Nay more, the greater the truths which the divine oracles announce, the more willingly does the mind deem them worthy of belief. And should we expect any favour from heaven, we are not discouraged by the greatness of the desired benefit, but are cheered and confirmed by frequently considering that there is nothing which an omnipotent God cannot effect.
