You are wont, indeed, to bring up against us the letters of Cyprian, his opinion, his Council; why do ye claim the authority of Cyprian for your schism, and reject his example when it makes for the peace of the Church? But who can fail to be aware that the sacred canon of Scripture, both of the Old and New Testament, is confined within its own limits, and that it stands so absolutely in a superior position to all later letters of the bishops, that about it we can hold no manner of doubt or disputation whether what is confessedly contained in it is right and true; but that all the letters of bishops which have been written, or are being written, since the closing of the canon, are liable to be refuted if there be anything contained in them which strays from the truth, either by the discourse of some one who happens to be wiser in the matter than themselves, or by the weightier authority and more learned experience of other bishops, by the authority of Councils; and further, that the Councils themselves, which are held in the several districts and provinces, must yield, beyond all possibility of doubt, to the authority of plenary Councils which are formed for the whole Christian world; and that even of the plenary Councils, the earlier are often corrected by those which follow them, when, by some actual experiment, things are brought to light which were before concealed, and that is known which previously lay hid, and this without any whirlwind of sacrilegious pride, without any puffing of the neck through arrogance, without any strife of envious hatred, simply with holy humility, catholic peace, and Christian charity?240
In referring to Cyprian, the third century North African Church father, Augustine drew a distinction between his writings and the Scriptures, saying that his writings were to be received as authoritative only when it could be demonstrated they were consistent with the truth of Scripture. He claimed the liberty to reject any writings which contradicted or could not be validated from Scripture:
We do no injustice to Cyprian when we make a distinction between his epistles and the canonical authority of the divine Scriptures. Apart from the Sacred canonical Scriptures, we may freely pass judgment on the writings of believers and disbelievers alike...For that reason Cyprian’s epistles, which have no canonical authority must be judged according to their agreement with the authority of the divine writings. Thus we can accept from Cyprian only what agrees, and safely reject what does not agree, with Scripture.241
This was his position on the writings of all the bishops of the Church, including himself:
For the reasonings of any men whatsoever, even though they be Catholics, and of high reputation, are not to be treated by us in the same way as the canonical Scriptures are treated. We are at liberty, without doing any violence to the respect which these men deserve, to condemn and reject anything in their writings, if perchance we shall find that they have entertained opinions differing from that which others or we ourselves have, by the divine help, discovered to be the truth. I deal thus with the writings of others, and I wish my intelligent readers to deal thus with mine.242
Thomas Aquinas reiterates the same perspective, even quoting Augustine approvingly as an authority for his convictions.243 It is clear that Augustine believed and taught that the Church’s authority is contingent on her adherence to Scripture; where she deviates from that standard she is to be rejected. The true Church of Jesus Christ is evidenced by conformity to Scripture alone.244 Scripture is the foundation of the Church:
Intending to speak, in dependence on God’s grace, of the day of His final judgment, and to affirm it against the ungodly and incredulous, we must first of all lay, as it were, in the foundation of the edifice, the divine declarations.245
Augustine also taught that Scripture is sufficient as the source of all truth and is the final arbiter in all theological controversies. He wrote:
For holy Scripture setteth a rule to our teaching, that we dare not ‘be wise more than it behoveth to be wise;’ but be wise, as himself saith, ‘unto soberness, according as unto each God hath allotted the measure of faith.’ Be it not therefore for me to teach you any other thing, save to expound to you the words of the Teacher, and to treat of them as the Lord shall have given to me.246 Â
According to Augustine, all that is sufficient for salvation is contained in Scripture, meaning that there are no truths necessary for salvation and handed down from Christ to the Church through the apostles which are independent of Scripture. All that Christ desired for us to know, he commanded to be written, and what has been written is sufficient for salvation.247 Â
Augustine’s view of the sufficiency of Scripture is seen in his exposition of the creed for catechumens. In it he reiterated what Cyril of Jerusalem, Irenaeus and Tertullian taught, that the rule of faith is derived and proved from Scripture alone:
Receive, my children, the Rule of Faith, which is called the Symbol (or Creed). And when ye have received it, write it in your heart, and be daily saying it to yourselves; before ye sleep, before ye go forth, arm you with your Creed. The Creed no man writes so as it may be able to be read: but for rehearsal of it, lest haply forgetfulness obliterate what care hath delivered, let your memory be your record–roll: what ye are about to hear, that are ye to believe; and what ye shall have believed, that are about to give back with your tongue. For the Apostle says, ‘With the heart man believeth unto righteousness, and with the mouth confession is made unto salvation.’ For this is the Creed which ye are to rehearse and to repeat in answer. These words which ye have heard are in the Divine Scriptures scattered up and down: but thence gathered and reduced into one, that the memory of slow persons might not be distressed; that every person may be able to say, able to hold, what he believes.248
The specific doctrines of the Symbol or the Creed are listed by Augustine in his sermon On Faith and the Creed:
We believe in God the Father Almighty, the creator of all things…In Jesus Christ, the Son of God, the only–begotten of the Father, that is to say, His only Son our Lord...Who under Pontius Pilate was crucified and buried…On the third day he arose again from the dead…He ascended into heaven...He sits at the right hand of the Father...He will come from thence and will judge the quick and the dead...We believe in the Holy Ghost; the holy Church…catholic, the remission of sins and the resurrection of the flesh.249 Â
