inundado por um mistério de luz que é Deus e N´Ele vi e ouvi -A ponta da lança como chama que se desprende, toca o eixo da terra, – Ela estremece: montanhas, cidades, vilas e aldeias com os seus moradores são sepultados. - O mar, os rios e as nuvens saem dos seus limites, transbordam, inundam e arrastam consigo num redemoinho, moradias e gente em número que não se pode contar , é a purificação do mundo pelo pecado em que se mergulha. - O ódio, a ambição provocam a guerra destruidora! - Depois senti no palpitar acelerado do coração e no meu espírito o eco duma voz suave que dizia: – No tempo, uma só Fé, um só Batismo, uma só Igreja, Santa, Católica, Apostólica: - Na eternidade, o Céu! 
MEDIATOR DEI
ENCYCLICAL OF POPE PIUS XII
ON THE SACRED LITURGY
TO THE VENERABLE BRETHREN, THE PATRIARCHS, PRIMATES,
ARCHBISHOPS, BISHIOPS, AND OTHER ORDINARIES
IN PEACE AND COMMUNION WITH THE APOSTOLIC SEE
8. Indeed, though we are sorely grieved to note, on the one hand, that there are places where the spirit, understanding or practice of the sacred liturgy is defective, or all but inexistent, We observe with considerable anxiety and some misgiving, that elsewhere certain enthusiasts, over-eager in their search for novelty, are straying beyond the path of sound doctrine and prudence. Not seldom, in fact, they interlard their plans and hopes for a revival of the sacred liturgy with principles which compromise this holiest of causes in theory or practice, and someTimes New Roman even taint it with errors touching Catholic faith and ascetical doctrine.
9. Yet the integrity of faith and morals ought to be the special criterion of this sacred science, which must conform exactly to what the Church out of the abundance of her wisdom teaches and prescribes. It is, consequently, Our prerogative to commend and approve whatever is done properly, and to check or censure any aberration from the path of truth and rectitude.
10. Let not the apathetic or half-hearted imagine, however, that We agree with them when We reprove the erring and restrain the overbold. No more must the imprudent think that we are commending them when We correct the faults of those who are negligent and sluggish.
11. If in this encyclical letter We treat chiefly of the Latin liturgy, it is not because We esteem less highly the venerable liturgies of the Eastern Church, whose ancient and honorable ritual traditions are just as dear to Us. The reason lies rather in a special situation prevailing in the Western Church, of sufficient importance, it would seem, to require this exercise of Our authority.
12. With docile hearts, then, let all Christians hearken to the voice of their Common Father, who would have them, each and every one, intimately united with him as they approach the altar of God, professing the same faith, obedient to the same law, sharing in the same Sacrifice with a single intention and one sole desire. This is a duty imposed, of course, by the honor due to God. But the needs of our day and age demand it as well. After a long and cruel war which has rent whole peoples asunder with it rivalry and slaughter, men of good will are spending themselves in the effort to find the best possible way to restore peace to the world. It is, notwithstanding, Our belief that no plan or initiative can offer better prospect of success than that fervent religious spirit and zeal by which Christians must be formed and guided; in this way their common and whole-hearted acceptance of the same truth, along with their united obedience and loyalty to their appointed pastors, while rendering to God the worship due to Him, makes of them one brotherhood: "for we, being many, are one body: all that partake of one bread."[9]
13. It is unquestionably the fundamental duty of man to orientate his person and his life towards God. "For He it is to whom we must first be bound, as to an unfailing principle; to whom even our free choice must be directed as to an ultimate objective. It is He, too, whom we lose when carelessly we sin. It is He whom we must recover by our faith and trust."[10] But man turns properly to God when he acknowledges His Supreme majesty and supreme authority; when he accepts divinely revealed truths with a submissive mind; when he scrupulously obeys divine law, centering in God his every act and aspiration; when he accords, in short, due worship to the One True God by practicing the virtue of religion.
14. This duty is incumbent, first of all, on men as individuals. But it also binds the whole community of human beings, grouped together by mutual social ties: mankind, too, depends on the sovereign authority of God.
15. It should be noted, moreover, that men are bound by his obligation in a special way in virtue of the fact that God has raised them to the supernatural order.
