*That Apostolic means, in part Apostolic Succession...
Adversus Haereses (Book III, Chapter 3)
A refutation of the heretics, from the fact that, in the various Churches, a perpetual succession of bishops was kept up.
1. It is within the power of all, therefore, in every Church, who may wish to see the truth, to contemplate clearly the tradition of the apostles manifested throughout the whole world; and we are in a position to reckon up those who were by the apostles instituted bishops in the Churches, and [to demonstrate] the succession of these men to our own times; those who neither taught nor knew of anything like what these [heretics] rave about. For if the apostles had known hidden mysteries, which they were in the habit of imparting to "the perfect" apart and privily from the rest, they would have delivered them especially to those to whom they were also committing the Churches themselves. For they were desirous that these men should be very perfect and blameless in all things, whom also they were leaving behind as their successors, delivering up their own place of government to these men; which men, if they discharged their functions honestly, would be a great boon [to the Church], but if they should fall away, the direst calamity.
2. 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.
3. The blessed apostles, then, having founded and built up the Church, committed into the hands of Linus the office of the episcopate. Of this Linus, Paul makes mention in the Epistles to Timothy. To him succeeded Anacletus; and after him, in the third place from the apostles, Clement was allotted the bishopric. This man, as he had seen the blessed apostles, and had been conversant with them, might be said to have the preaching of the apostles still echoing [in his ears], and their traditions before his eyes. Nor was he alone [in this], for there were many still remaining who had received instructions from the apostles. In the time of this Clement, no small dissension having occurred among the brethren at Corinth, the Church in Rome despatched a most powerful letter to the Corinthians, exhorting them to peace, renewing their faith, and declaring the tradition which it had lately received from the apostles, proclaiming the one God, omnipotent, the Maker of heaven and earth, the Creator of man, who brought on the deluge, and called Abraham, who led the people from the land of Egypt, spoke with Moses, set forth the law, sent the prophets, and who has prepared fire for the devil and his angels. From this document, whosoever chooses to do so, may learn that He, the Father of our Lord Jesus Christ, was preached by the Churches, and may also understand the apostolical tradition of the Church, since this Epistle is of older date than these men who are now propagating falsehood, and who conjure into existence another god beyond the Creator and the Maker of all existing things. To this Clement there succeeded Evaristus. Alexander followed Evaristus; then, sixth from the apostles, Sixtus was appointed; after him, Telephorus, who was gloriously martyred; then Hyginus; after him, Pius; then after him, Anicetus. Sorer having succeeded Anicetus, Eleutherius does now, in the twelfth place from the apostles, hold the inheritance of the episcopate. In this order, and by this succession, the ecclesiastical tradition from the apostles, and the preaching of the truth, have come down to us. And this is most abundant proof that there is one and the same vivifying faith, which has been preserved in the Church from the apostles until now, and handed down in truth.
4. But Polycarp also was not only instructed by apostles, and conversed with many who had seen Christ, but was also, by apostles in Asia, appointed bishop of the Church in Smyrna, whom I also saw in my early youth, for he tarried [on earth] a very long time, and, when a very old man, gloriously and most nobly suffering martyrdom, departed this life, having always taught the things which he had learned from the apostles, and which the Church has handed down, and which alone are true. To these things all the Asiatic Churches testify, as do also those men who have succeeded Polycarp down to the present time,—a man who was of much greater weight, and a more steadfast witness of truth, than Valentinus, and Marcion, and the rest of the heretics. He it was who, coming to Rome in the time of Anicetus caused many to turn away from the aforesaid heretics to the Church of God, proclaiming that he had received this one and sole truth from the apostles,—that, namely, which is handed down by the Church. There are also those who heard from him that John, the disciple of the Lord, going to bathe at Ephesus, and perceiving Cerinthus within, rushed out of the bath-house without bathing, exclaiming, "Let us fly, lest even the bath-house fall down, because Cerinthus, the enemy of the truth, is within." And Polycarp himself replied to Marcion, who met him on one occasion, and said, "Do you know me?" "I do know you, the first-born of Satan." Such was the horror which the apostles and their disciples had against holding even verbal communication with any corrupters of the truth; as Paul also says, "A man that is an heretic, after the first and second admonition, reject; knowing that he that is such is subverted, and sinneth, being condemned of himself." Titus 3:10 There is also a very powerful Epistle of Polycarp written to the Philippians, from which those who choose to do so, and are anxious about their salvation, can learn the character of his faith, and the preaching of the truth. Then, again, the Church in Ephesus, founded by Paul, and having John remaining among them permanently until the times of Trajan, is a true witness of the tradition of the apostles.
*THAT'S TRADITION AND ORTHOPRAXIS.
Acts 1:20...For it is written in the book of Psalms: Let their habitation become desolate, and let there be none to dwell therein. And his bishopric let another take.
2 Tim 1:6...Bishop Paul Ordains Timothy... For which cause I admonish thee, that thou stir up the grace of God which is in thee, by the imposition of my hands.
Titus 1...Bishop Paul reminds Titus he ordained him Bishop and as Bishop, Titus will ordain priests...For this cause I left thee in Crete, that thou shouldest set in order the things that are wanting, and shouldest ordain priests in every city, as I also appointed thee:
*THAT'S SCRIPTURE
Lumen Gentium
That divine mission, entrusted by Christ to the apostles, will last until the end of the world, since the Gospel they are to teach is for all time the source of all life for the Church. And for this reason the apostles, appointed as rulers in this society, took care to appoint successors.
For they not only had helpers in their ministry, but also, in order that the mission assigned to them might continue after their death, they passed on to their immediate cooperators, as it were, in the form of a testament, the duty of confirming and finishing the work begun by themselves, recommending to them that they attend to the whole flock in which the Holy Spirit placed them to shepherd the Church of God. They therefore appointed such men, and gave them the order that, when they should have died, other approved men would take up their ministry. Among those various ministries which, according to tradition, were exercised in the Church from the earliest times, the chief place belongs to the office of those who, appointed to the episcopate, by a succession running from the beginning, are passers-on of the apostolic seed. Thus, as St. Irenaeus testifies, through those who were appointed bishops by the apostles, and through their successors down ln our own time, the apostolic tradition is manifested and preserved.
Bishops, therefore, with their helpers, the priests and deacons, have taken up the service of the community, presiding in place of God over the flock, whose shepherds they are, as teachers for doctrine, priests for sacred worship, and ministers for governing. And just as the office granted individually to Peter, the first among the apostles, is permanent and is to be transmitted to his successors, so also the apostles' office of nurturing the Church is permanent, and is to be exercised without interruption by the sacred order of bishops. Therefore, the Sacred Council teaches that bishops by divine institution have succeeded to the place of the apostles, as shepherds of the Church, and he who hears them, hears Christ, and he who rejects them, rejects Christ and Him who sent Christ.
... For the discharging of such great duties, the apostles were enriched by Christ with a special outpouring of the Holy Spirit coming upon them, and they passed on this spiritual gift to their helpers by the imposition of hands, and it has been transmitted down to us in episcopal consecration. And the Sacred Council teaches that by episcopal consecration the fullness of the sacrament of Orders is conferred, that fullness of power, namely, which both in the Church's liturgical practice and in the language of the Fathers of the Church is called the high priesthood, the supreme power of the sacred ministry. But episcopal consecration, together with the office of sanctifying, also confers the office of teaching and of governing, which, however, of its very nature, can be exercised only in hierarchical communion with the head and the members of the college. For from the tradition, which is expressed especially in liturgical rites and in the practice of both the Church of the East and of the West, it is clear that, by means of the imposition of hands and the words of consecration, the grace of the Holy Spirit is so conferred, and the sacred character so impressed, that bishops in an eminent and visible way sustain the roles of Christ Himself as Teacher, Shepherd and High Priest, and that they act in His person. Therefore it pertains to the bishops to admit newly elected members into the episcopal body by means of the sacrament of Orders.
*THAT IS CHURCH TEACHING
* Now, I have posted Teaching from Scripture, Tradition, and Church. That is the way our Triune God, in his Threefold Treatise on Truth, Teaches us. It has been this way, as I have just shown, from the get go. There is no such orthodox belief known as Sola Scriptura I have just illustrated the reality of Church, Tradition, Scripture, which, is both their appearance in Christian Chronological order, and also the the Rule of Faith. Let he who has ears hear.
