There are two special forms of labour to which the Apostle gives prominence: he mentions as among those that labour "them that are over you in the Lord, and admonish you." The first of the words here employed, the one translated "them that are over" you, is the only hint the Epistle contains of Church government. Wherever there is a society, there must be order. There must be those through whom the society acts, those who represent it officially by words or deeds. At Thessalonica there was not a single president, a minister in our sense, possessing to a certain extent an exclusive responsibility; the presidency was in the hands of a plurality of men, what Presbyterians would call a Kirk Session. This body, as far as we can make out from the few surviving indications of their duties, would direct, but not conduct, the public worship, and would manage the financial affairs, and especially the charity, of the church. They would as a rule be elderly men; and were called by the official name, borrowed from the Jews, of elders. They did not, in the earliest times, preach or teach; they were too old to learn that new profession; but what may be called the administration was in their hands; they were the governing committee of the new Christian community. The limits of their authority are indicated by the words "in the Lord." They are over the members of the church in their characters and relations as church members; but they have nothing to do with other departments of life, so far as these relations are unaffected by them.
Side by side with those who preside over the church, Paul mentions those "who admonish you." Admonish is a somewhat severe word; it means to speak to one about his conduct, reminding him of what he seems to have forgotten, and of what is rightly expected from him. It gives us a glimpse of discipline in the early Church, that is, of the care which was taken that those who had named the Christian name should lead a truly Christian life. There is nothing expressly said in this passage about doctrines. Purity of doctrine is certainly essential to the health of the Church, but rightness of life comes before it. There is nothing expressly said about teaching the truth; that work belonged to apostles, prophets, and evangelists, who were ministers of the Church at large, and not fixed to a single congregation; the only exercise of Christian speech proper to the congregation is its use in admonition, _i.e._, for practical moral purposes. The moral ideal of the gospel must be clearly before the mind of the Church, and all who deviate from it must be admonished of their danger. "It is difficult for us in modern times," says Dr. Hatch, "with the widely different views which we have come to hold as to the relation of Church government to social life, to understand how large a part discipline filled in the communities of primitive times. These communities were what they were mainly by the strictness of their discipline.... In the midst of 'a crooked and perverse nation' they could only hold their own by the extreme of circumspection. Moral purity was not so much a virtue at which they were bound to aim as the very condition of their existence. If the salt of the earth should lose its savour, wherewith should it be salted? If the lights of the world were dimmed, who should rekindle their flame? And of this moral purity the officers of each community were the custodians. 'They watched for souls as those that must give account.'" This vivid picture should provoke us to reflection. Our minds are not set sufficiently on the practical duty of keeping up the Christian standard. The moral originality of the gospel drops too easily out of sight. Is it not the case that we are much more expert at vindicating the approach of the Church to the standard of the non-Christian world, than at maintaining the necessary distinction between the two? We are certain to bring a good deal of the world into the Church without knowing it; we are certain to have instincts, habits, dispositions, associates perhaps, and likings, which are hostile to the Christian type of character; and it is this which makes admonition indispensable. Far worse than any aberration in thought is an irregularity in conduct which threatens the Christian ideal. When you are warned of such a thing in your conduct by your minister or elder, or by any Christian, do not resent the warning. Take it seriously and kindly; thank God that He has not allowed you to go on unadmonished; and esteem very highly in love the brother or sister who has been so true to you. Nothing is more un-Christian than fault-finding, nothing is more truly Christian than frank and affectionate admonishing of those who are going astray. This may be especially commended to the young. In youth we are apt to be proud and wilful; we are confident that we can keep ourselves safe in what the old and timid consider dangerous situations; we do not fear temptation, nor think that this or that little fall is more than an indiscretion; and, in any case, we have a determined dislike to being interfered with. All this is very natural; but we should remember that, as Christians, we are pledged to a course of life which is not in all ways natural; to a spirit and conduct which are incompatible with pride; to a seriousness of purpose, to a loftiness and purity of aim, which may all be lost through wilfulness; and we should love and honour those who put their experience at our service, and warn us when, in lightness of heart, we are on the way to make shipwreck of our life. They do not admonish us because they like it, but because they love us and would save us from harm; and love is the only recompense for such a service.
