The so-called letters to the seven churches were never intended to be circulated separately. From the beginning the letters formed part of the Apocalypse, which was addressed to all seven of the churches. From the beginning, therefore, each of the letters was intended to be read not only by the church whose name it bears, but also by all the others. The seven churches, moreover, are representative of the Church at large.
Nevertheless, despite the universal purpose of the letters, they are very concrete in the information that they provide about the churches in Asia Minor. Like the Second and Third Epistles of John they illumine an exceedingly obscure period in the history of Christianity.
(1) The "Angels" of the Churches.—Some details in the letters, it is true, are to us obscure. What, for example, is meant by the "angels" of the churches to which the several letters are addressed? The Greek word translated "angel" may also mean simply "messenger." Conceivably, it might designate merely a congregational officer. Many have supposed that it designates a bishop. In the epistles of Ignatius, which were written not very many years after the Apocalypse, the term "bishop" is applied to an officer who had supreme authority over a congregation including the presbyters. The appearance of these "angels" or "messengers" in the Apocalypse has been urged as proof that John as well as Ignatius recognized the institution of the episcopacy.
Surely, however, the matter is more than doubtful. The Greek word used, whether it be translated "angel" or "messenger," is a very strange designation of a bishop. Moreover, in the rest of the Johannine literature there is no recognition of the episcopacy. In the Third Epistle of John, for example, even if Diotrephes had set himself up as a bishop—which is itself exceedingly doubtful—his claim is certainly not accepted by the apostle.
On the whole, it seems better to regard the "angels" to which the seven letters of the Apocalypse are addressed merely as ideal representatives of the churches—representatives conceived of perhaps as guardian angels. Compare Matt. 18:10.
(2) The Nicolaitans.—Another puzzling question concerns the "Nicolaitans" who appear in several of the letters. The name itself is obscure. By tradition it is connected with that Nicolaüs of Antioch who was one of the seven men appointed in the early days of the Jerusalem church to attend to the administration of charity. Acts 6:5. The tradition may possibly be correct. If it is correct, then Nicolaüs, in his later life, had not justified the confidence originally reposed in him.
At the first mention of the Nicolaitans, in the letter to Ephesus, Rev. 2:6, nothing whatever is said about their tenets. Their error, however, was not merely theoretical, but practical, for it was their "works" that the Lord is represented as hating. In the letter to Pergamum, the Nicolaitans are probably meant in v. 14. Like Balaam, they enticed the people of God to idolatry and impurity. The form which their idolatry took was the eating of meats offered to idols. The question of meats offered to idols was no simple matter. In the First Epistle to the Corinthians Paul had permitted the eating of such meats under certain circumstances, but had sternly forbidden it wherever it involved real or supposed participation in idolatrous worship. The form in which it was favored by the Nicolaitans evidently fell under the latter category. In a time of persecution, the temptation to guilty compromise with heathenism must have been insidious; and also the low morality of the Asian cities threatened ever and again to drag Christian people back into the impure life of the world.
In the letter to Thyatira, also, "the woman Jezebel" is apparently to be connected with the same sect, for the practical faults in Thyatira and in Pergamum were identical. Jezebel, the Phœnician wife of Ahab, was, like Balaam, a striking Old Testament example of one who led Israel into sin. It is significant that the woman Jezebel in Thyatira called herself a prophetess. Rev. 2:20. This circumstance seems to indicate that the Nicolaitans had excused their moral laxness by an appeal to special revelations. The impression is confirmed by v. 24. Apparently the Nicolaitans had boasted of their knowledge of the "deep things," and had despised the simple Christians who contented themselves with a holy life. At any rate, whatever particular justification the Nicolaitans advanced for their immoral life, they could not deceive the all-searching eye of Christ. Their "deep things" were deep things, not of God, but of Satan!
Who is meant by "the woman Jezebel"? Some interpreters, who suppose that the "angel" of the church was the bishop, regard Jezebel as a designation of the bishop's wife. This whole interpretation is, however, beset with serious difficulty. Perhaps "the woman Jezebel" does not refer to an individual at all, but is simply a figurative designation of the Nicolaitan sect. The description of the coming retribution in vs. 21-23 seems to be highly figurative.
It will be observed that the sin of the churches at Pergamum and Thyatira was not limited to those who actually accepted the Nicolaitan teaching. Even to endure the presence of the guilty sect was the object of the Lord's rebuke. Toward the works of the Nicolaitans only hatred was in place. Rev. 2:6. That is a solemn lesson for modern indifferentism. Tolerance is good; but there are times when it is a deadly sin.
