Chapter 1.—1.  I must express my satisfaction, and congratulations, and admiration, my son Boniface,^24682468     The correspondence between Augustin and Boniface is limited to Epp. 185, 189 and 220.  The sixteen smaller letters are spurious.  For note to Boniface and translations of 189 and 220, see vol. I of this series pp. 552 and 573. in that, amid all the cares of wars and arms, you are eagerly anxious to know concerning the things that are of God.  From hence it is clear that in you it is actually a part of your military valor to serve in truth the faith which is in Christ.  To place, therefore, briefly before your Grace the difference between the errors of the Arians and the Donatists, the Arians say that the Father, the Son, and the Holy Ghost are different in substance; whereas the Donatists do not say this, but acknowledge the unity of substance in the Trinity.  And if some even of them have said that the Son was inferior to the Father, yet they have not denied that He is of the same substance; whilst the greater part of them declare that they hold entirely the same belief regarding the Father and the Son and the Holy Ghost as is held by the Catholic Church.  Nor is this the actual question in dispute with them; but they carry on their unhappy strife solely on the question of communion, and in the perversity of their error maintain rebellious hostility against the unity of Christ.  But sometimes, as we have heard, some of them, wishing to conciliate the Goths, since they see that they are not without a certain amount of power, profess to entertain the same belief as they.  But they are refuted by the authority of their own leaders; for Donatus himself, of whose party they boast themselves to be, is never said to have held this belief.

2.  Let not, however, things like these disturb thee, my beloved son.  For it is foretold to us that there must needs be heresies and stumbling-blocks, that we may be instructed among our enemies; and that so both our 634faith and our love may be the more approved,—our faith, namely, that we should not be deceived by them; and our love, that we should take the utmost pains we can to correct the erring ones themselves; not only watching that they should do no injury to the weak, and that they should be delivered from their wicked error, but also praying for them, that God would open their understanding, and that they might comprehend the Scriptures.  For in the sacred books, where the Lord Christ is made manifest, there is also His Church declared; but they, with wondrous blindness, while they would know nothing of Christ Himself save what is revealed in the Scriptures, yet form their notion of His Church from the vanity of human falsehood, instead of learning what it is on the authority of the sacred books.

3.  They recognize Christ together with us in that which is written, "They pierced my hands and my feet.  They can tell all my bones:  they look and stare upon me.  They part my garments among them, and cast lots upon my vesture;" and yet they refuse to recognize the Church in that which follows shortly after:  "All the ends of the world shall remember, and turn unto the Lord; and all the kindreds of the nations shall worship before Thee.  For the kingdom is the Lord’s; and He is the Governor among the nations."^24692469     Ps. xxii. 16-18, 27, 28.   They recognize Christ together with us in that which is written, "The Lord hath said unto me, Thou art my Son, this day have I begotten Thee;" and they will not recognize the Church in that which follows:  "Ask of me, and I shall give Thee the heathen for Thine inheritance, and the uttermost parts of the earth for Thy possession."^24702470     Ps. ii. 7, 8.   They recognize Christ together with us in that which the Lord Himself says in the gospel, "Thus it behoved Christ to suffer, and to rise from the dead the third day;" and they will not recognize the Church in that which follows:  "And that repentance and remission of sins should be preached in His name among all nations, beginning at Jerusalem."^24712471     Luke xxiv. 46, 47.   And the testimonies in the sacred books are without number, all of which it has not been necessary for me to crowd together into this book.  And in all of them, as the Lord Christ is made manifest, whether in accordance with His Godhead, in which He is equal to the Father, so that, "In the beginning was the Word, and; the Word was with God, and the Word was God;" or according to the humility of the flesh which He took upon Him, whereby "the Word was made flesh and dwelt among us;"^24722472     John i. 1, 4. so is His Church made manifest, not in Africa alone, as they most impudently venture in the madness of their vanity to assert, but spread abroad throughout the world.

4.  For they prefer to the testimonies of Holy Writ their own contentions, because, in the case of Cæcilianus, formerly a bishop of the Church of Carthage, against whom they brought charges which they were and are unable to substantiate, they separated themselves from the Catholic Church,—that is, from the unity of all nations.  Although, even if the charges had been true which were brought by them against Cæcilianus, and could at length be proved to us, yet, though we might pronounce an anathema upon him even in the grave,^24732473     This epistle was produced in the fifth conference of the fifth ecumenical Synod (553), when the point was under debate whether Theodorus of Mopsuesta could be condemned after his death. we are still bound not for the sake of any man to leave the Church, which rests for its foundation on divine witness, and is not the figment of litigious opinions, seeing that it is better to trust in the Lord than to put confidence in man.^24742474     Ps. cxviii. 8.   For we cannot allow that if Cæcilianus had erred,—a supposition which I make without prejudice to his integrity,—Christ should therefore have forfeited His inheritance.  It is easy for a man to believe of his fellow-men either what is true or what is false; but it marks abandoned impudence to desire to condemn the communion of the whole world on account of charges alleged against a man, of which you cannot establish the truth in the face of the world.

5.  Whether Cæcilianus was ordained by men who had delivered up the sacred books, I do not know.  I did not see it, I heard it only from his enemies.  It is not declared to me in the law of God, or in the utterances of the prophets, or in the holy poetry of the Psalms, or in the writings of any one of Christ’s apostles, or in the eloquence of Christ Himself.  But the evidence of all the several scriptures with one accord proclaims the Church spread abroad throughout the world, with which the faction of Donatus does not hold communion.  The law of God declared, "In thy seed shall all the nations of the earth be blessed."^24752475     Gen. xxvi. 4.   The Lord said by the mouth of His prophet, "From the rising of the sun, even unto the going down of the same, a pure sacrifice shall be offered unto my name:  for my name shall be great among the heathen."^24762476     Mal. i. 11.   The Lord said through the Psalmist, "He shall have dominion also from sea to sea, and from the river unto the ends of the earth."^24772477     Ps. lxxii. 8.   The Lord said by His apostle, 635"The gospel is come unto you, as it is in all the world, and bringeth forth fruit."^24782478     Col. i. 6.   The Son of God said with His own mouth, "Ye shall be witnesses unto me, both in Jerusalem, and in all Judea, and in Samaria, and even unto the uttermost part of the earth."^24792479     Acts i. 8.   Cæcilianus, the bishop of the Church of Carthage, is accused with the contentiousness of men; the Church of Christ, established among all nations, is recommended by the voice of God.  Mere piety, truth, and love forbid us to receive against Cæcilianus the testimony of men whom we do not find in the Church, which has the testimony of God; for those who do not follow the testimony of God have forfeited the weight which otherwise would attach to their testimony as men.
