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.
