In the previous article, we discussed the terms bishop, presbyter (priest), and deacon and how these terms had fixed meanings by the beginning of the 2nd century.  The question was then asked, is this sound doctrine that the churches should be governed by this three tiered hierarchy? We will now take a look at the words of two early and trustworthy witnesses.
Witness #1: St. Ignatius of Antioch
According to Eusebius’ Church History  , Ignatius succeeded Evodius as bishop of Antioch, who himself had succeeded St. Peter.  While St. Ignatius was being transferred from Antioch to Rome where he was to be martyred by being fed to wild beasts in the arena, he wrote 7 epistles which are now extant: six to various churches on the way (and to Rome itself) and one to St. Polycarp, bishop of Smyrna.
In these epistles (excepting the one to Rome and possibly the one to St. Polycarp himself), we clearly see a snapshot of the monarchical bishop in existence in the churches.
Here are a couple of excerpts to prove the point:
“Take heed, then, to have but one Eucharist. For there is one flesh of our Lord Jesus Christ, and one cup to [show forth ] the unity of His blood; one altar; as there is one bishop, along with the presbytery and deacons, my fellow-servants: that so, whatsoever you do, you may do it according to [the will of] God.” (Epistle to the Philadelphians) 
“See that you all follow the bishop, even as Jesus Christ does the Father, and the presbytery as you would the apostles; and reverence the deacons, as being the institution of God. Let no man do anything connected with the Church without the bishop. Let that be deemed a proper Eucharist, which is [administered] either by the bishop, or by one to whom he has entrusted it. Wherever the bishop shall appear, there let the multitude [of the people] also be; even as, wherever Jesus Christ is, there is the Catholic Church. It is not lawful without the bishop either to baptize or to celebrate a love-feast; but whatsoever he shall approve of, that is also pleasing to God, so that everything that is done may be secure and valid.” (Epistle to the Smyrnaeans) 
This second excerpt is from St. Ignatius’ Epistle to the Smyrnaeans, who at that time had for their bishop St. Polycarp. He is our second witness to the orthodoxy on this view of church governance.
Witness #2: St. Polycarp
St. Polycarp was the first bishop of Smyrna (modern day Izmir, Turkey), and was a disciple of St. John (who was a disciple of Jesus Christ as well as the author of the 4th Gospel.) He died a martyr, ultimately by the sword after having been set on a pyre that was then ignited with fire (one may read the account here.) He was a contemporary of our first witness (St. Ignatius of Antioch), who actually wrote one letter to his church and one letter to St. Polycarp personally. Only one of St. Polycarp’s writings is extant today which is The Epistle of Polycarp to the Phillipians (yes, the same church St. Paul wrote to.) Towards the end of this letter we read:
“I am sending you Ignatius’s letters, as you requested; the ones he wrote to us, and some others that we had in our possession. They are enclosed herewith; you will be able to derive a great deal of benefit from them, for they tell you all about faith, and perseverance, and all the ways of self improvement that involve our Lord.” 
Now, St. Polycarp doesn’t say that he has all seven letters, but he does have (at least) some of them. This begs the question; if there was anything problematic written in St. Ignatius’s letters (those which St. Polycarp had) would he forward them on with what appears to be an endorsement? And what do we make of the matter that St. Polycarp, disciple of St. John, appears to be himself a monarchical bishop?
