Catechism of the Council of Trent: The Holy Catholic Church, the communion of saints
Article 9. "I Believe in the Holy Catholic Church; the Communion of Saints"
The Importance Of This Article
With what great diligence pastors ought to explain to the faithful the truth of this ninth Article will be easily seen, if we attend chiefly to two considerations.
First, as St. Augustine observes, the Prophets spoke more plainly and openly of the Church than of Christ, foreseeing that on this a much greater number may err and be deceived than on the mystery of the Incarnation. For in after ages there would not be wanting wicked men who, like the ape that would fain pass for a man, would claim that they alone were Catholics, and with no less impiety than effrontery assert that with them alone is the Catholic Church.
The second consideration is that he whose mind is strongly impressed with the truth taught in this Article, will easily escape the awful danger of heresy. For a person is not to be called a heretic as soon as he shall have offended in matters of faith; but he is a heretic who, having disregarded the authority of the Church, maintains impious opinions with pertinacity. Since, therefore, it is impossible that anyone be infected with the contagion of heresy, so long as he holds what this Article proposes to be believed, let pastors use every diligence that the faithful, having known this mystery and guarded against the wiles of Satan, may persevere in the true faith.
This Article hinges upon the preceding one; for, it having been already shown that the Holy Ghost is the source and giver of all holiness, we here profess our belief that the Church has been endowed by Him with sanctity.
First Part Of This Article: "I Believe In The Holy Catholic Church"
The Latins, having borrowed the word ecclesia (church) from the Greeks, have transferred it, since the preaching of the Gospel, to sacred things. It becomes necessary, therefore, to explain its meaning.
"Church"
The word ecclesia (church) means a calling forth. But writers afterward used it to signify a meeting or assembly, whether the people gathered together were members of a true or of a false religion. Thus in the Acts it is written of the people of Ephesus that when the town-clerk had appeased a tumultuous assemblage he said: And if you inquire after any other matter, it may be decided in a lawful church. The Ephesians, who were worshippers of Diana, are thus called a lawful church (ecclesia). Nor are the Gentiles only, who knew not God, called a church (ecclesia); by the same name at times are also designated the councils of wicked and impious men. I have hated the church (ecclesiam) of the malignant, says the Prophet, and with the wicked I will not sit.
In common Scripture usage, however, the word was subsequently employed to signify the Christian society only, and the assemblies of the faithful; that is, of those who are called by faith to the light of truth and the knowledge of God, that, having forsaken the darkness of ignorance and error, they may worship the living and true God piously and holily, and serve Him from their whole heart. In a word, The Church, says St. Augustine, consists of the faithful dispersed throughout the world.
Mysteries Which The Word Church Comprises
In this word are contained important mysteries. For, in the calling forth, which it signifies, we recognise at once the benignity and splendour of divine grace, and we understand that the Church is very unlike all other societies. Other bodies rest on human reason and prudence, but the Church reposes on the wisdom and counsels of God who has called us inwardly by the inspiration of the Holy Ghost, who opens the hearts of men; and outwardly, through the labor and ministry of pastors and preachers.
Moreover, the end of this vocation, that is, the knowledge and possession of things eternal will be at once understood if we but remember why the faithful of the Old Law were called a Synagogue, that is, a flock; for, as St. Augustine teaches, they were so called, because, like cattle, which are wont to herd together, they looked only to terrestrial and transitory goods. Wherefore, the Christian people are justly called, not a Synagogue, but a Church, because, despising earthly and passing things, they pursue only things heavenly and eternal.
Other Names Given The Church In Scripture
Many names, moreover, which are replete with mysteries, have been used to designate the Christian body. Thus, by the Apostle, it is called the house and edifice of God. If, says he to Timothy, I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and ground of truth. The Church is called a house, because it is, as it were, one family governed by one father of the family, and enjoying a community of all spiritual goods.
It is also called the flock of the sheep of Christ, of which He is the door and the shepherd. It is called the spouse of Christ. I have espoused you to one husband, says the Apostle to the Corinthians, that I may present you as a chaste virgin to Christ; and to the Ephesians: Husbands love your wives, as Christ also loved the church; and of marriage: This is a great sacrament, but I speak in Christ and in the church.
Finally, the Church is called the body of Christ, as may be seen in the Epistles to the Ephesians and Colossians. Each of these appellations has very great influence in exciting the faithful to prove themselves worthy of the boundless clemency and goodness of God, who chose them to be the people of God.
The Parts of the Church
These things having been explained, it will be necessary to enumerate the several component parts of the Church, and to point out their difference, in order that the faithful may the better comprehend the nature, properties, gifts, and graces of God's beloved Church, and by reason of them unceasingly praise the most holy name of God.
The Church consists principally of two parts, the one called the Church triumphant; the other, the Church militant. The Church triumphant is that most glorious and happy assemblage of blessed spirits, and of those who have triumphed over the world, the flesh, and the iniquity of Satan, and are now exempt and safe from the troubles of this life and enjoy everlasting bliss. The Church militant is the society of all the faithful still dwelling on earth. It is called militant, because it wages eternal war with those implacable enemies, the world, the flesh and the devil.
We are not, however, to infer that there are two Churches. The Church triumphant and the Church militant are two constituent parts of one Church; one part going before, and now in the possession of its heavenly country; the other, following every day, until at length, united with our Saviour, it shall repose in endless felicity.
The Members Of The Church Militant
The Church militant is composed of two classes of persons, the good and the bad, both professing the same faith and partaking of the same Sacraments, yet differing in their manner of life and morality.
The good are those who are linked together not only by the profession of the same faith, and the participation of the same Sacraments, but also by the spirit of grace and the bond of charity. Of these St. Paul says: The Lord knoweth who are his. Who they are that compose this class we also may remotely conjecture, but we can by no means pronounce with certainty. Hence Christ the Saviour does not speak of this portion of His Church when He refers us to the Church and commands us to hear and to obey her. As this part of the Church is unknown, how could we ascertain with certainty whose decision to recur to, whose authority to obey?
The Church, therefore, as the Scriptures and the writings of the Saints testify, includes within her fold the good and the bad; and it was in this sense that St. Paul spoke of one body and one spirit. Thus understood, the Church is known and is compared to a city built on a mountain, and visible from every side. As all must yield obedience to her authority, it is necessary that she may be known by all.
That the Church is composed of the good and the bad we learn from many parables contained in the Gospel. Thus, the kingdom of heaven, that is, the Church militant, is compared to a net cast into the sea, to a field in which tares were sown with the good grain, to a threshing floor on which the grain is mixed up with the chaff, and also to ten virgins, some of whom were wise, and some foolish. And long before, we trace a figure and resemblance of this Church in the ark of Noah, which contained not only clean, but also unclean animals.
But although the Catholic faith uniformly and truly teaches that the good and the bad belong to the Church, yet the same faith declares that the condition of both is very different. The wicked are contained in the Church, as the chaff is mingled with the grain on the threshing floor, or as dead members sometimes remain attached to a living body.
