*]Sola Petra: To believe that only Peter mattered, and that the other Apostles were of little real consequence.
*]Sola Roma: To believe that only through the city of Rome is the charism of Peter the Apostle alive in the church.
*]Sola Suprema: To believe that only in the most supremely authoritative manner is the charism of Peter manifest in the church, with no other possible interpretation.
“Since, however, it would be very tedious, in such a volume as this, to reckon up the successions of all the Churches, we do put to confusion all those who, in whatever manner, whether by an evil self-pleasing, by vainglory, or by blindness and perverse opinion, assemble in unauthorized meetings; [we do this, I say,] by indicating that tradition derived from the apostles, of the very great, the very ancient, and universally known Church founded and organized at Rome by the two most glorious apostles, Peter and Paul; as also [by pointing out] the faith preached to men, which comes down to our time by means of the successions of the bishops.
For it is a matter of necessity that every Church should agree with this Church, on account of its pre-eminent authority, that is, the faithful everywhere, inasmuch as the apostolical tradition has been preserved continuously by those [faithful men] who exist everywhere.”
Irenaeus,Against Heresies,3:3:2 (A.D. 180),in ANF,I:1415-416
"Since the East, shattered as it is by the long-standing feuds, subsisting between its peoples, is bit by bit tearing into shreds the seamless vest of the Lord, woven from the top throughout,’ since the foxes are destroying the vineyard of Christ, and since among the broken cisterns that hold no water it is hard to discover the sealed fountain’ and the garden inclosed,’ I think it my duty to consult the chair of Peter, and to turn to a church whose faith has been praised by Paul. I appeal for spiritual food to the church whence I have received the garb of Christ. The wide space of sea and land that lies between us cannot deter me from searching for the pearl of great price.’ Wheresoever the body is, there will the eagles be gathered together.’ Evil children have squandered their patrimony; you alone keep your heritage intact. The fruitful soil of Rome, when it receives the pure seed of the Lord, bears fruit an hundredfold; but here the seed corn is choked in the furrows and nothing grows but darnel or oats. In the West the Sun of righteousness is even now rising; in the East, Lucifer, who fell from heaven, has once more set his throne above the stars. Ye are the light of the world,’ ye are the salt of the earth,’ ye are “vessels of gold and of silver.” Here are vessels of wood or of earth, which wait for the rod of iron,and eternal fire. Yet, though your greatness terrifies me, your kindness attracts me. From the priest I demand the safe-keeping of the victim, from the shepherd the protection due to the sheep. Away with all that is overweening; let the state of Roman majesty withdraw. **My words are spoken to the successor of the fisherman, to the disciple of the cross. As I follow no leader save Christ, so I communicate with none but your blessedness, that is with the chair of Peter. For this, I know, is the rock on which the church is built! This is the house where alone the paschal lamb can be rightly eaten. This is the ark of Noah, and he who is not found in it shall perish when the flood prevails. But since by reason of my sins I have betaken myself to this desert which lies between Syria and the uncivilized waste, I cannot, owing to the great distance between us, always ask of your sanctity the holy thing of the Lord. Consequently I here follow the Egyptian confessors who share your faith, and anchor my frail craft under the shadow of their great argosies. I know nothing of Vitalis; I reject Meletius; I have nothing to do with Paulinus. He that gathers not with you scatters; he that is not of Christ is of Antichrist." **
Jerome,To Pope Damasus,Epistle 15:1-2(A.D. 375),in NPNF2,VI:18
“After such things as these, moreover, they still dare–a false bishop having been appointed for them by, heretics–to set sail and to bear letters from schismatic and profane persons to the throne of Peter, and to the chief church whence priestly unity takes its source; and not to consider that these were the Romans whose faith was praised in the preaching of the apostle, to whom faithlessness could have no access.”
Cyprian,To Cornelius,Epistle 54/59:14(A.D. 252),in ANF,V:344
“You cannot deny that you know that in the city of Rome the Chair was first conferred on Peter, in which the prince of all the Apostles, Peter,sat … in which Chair unity should be preserved by all, so that he should now be a schismatic and a sinner who should set up another Chair against that unique one.”
Optatus of Mileve,The Schism of Donatists,2:2-3 (c.A.D. 367),in GCC,55
“Your grace must be besought not to permit any disturbance of the Roman Church, the head of the whole Roman World and of the most holy faith of the Apostles, for from thence flow out to all(churches) the bonds of sacred communion.”
Ambrose,To Emperor Gratian,Epistle 11:4(A.D. 381),in SPP,160
“But he was not so eager as to lay aside caution. He called the bishop to him, and esteeming that there can be no true thankfulness except it spring from true faith, he enquired whether he agreed with the Catholic bishops, that is, with the Roman Church?”
Ambrose,The death of his brother Satyrus,1:47(A.D. 378),in NPNF2,X:168
“I am held in the communion of the Catholic Church by…and by the succession of bishops from the very seat of Peter, to whom the Lord, after His resurrection commended His sheep to be fed up to the present episcopate.”
Augustine,Against the Letter of Mani,5(A.D. 395),in GCC,78
