The brevity of the inscription clearly shews that Paul’s doctrine had been received with reverence among the Thessalonians, and that without controversy they all rendered to him the honor that he deserved. For when in other Epistles he designates himself an Apostle, he does this for the purpose of claiming for himself authority. Hence the circumstance, that he simply makes use of his own name without any title of honor, is an evidence that those to whom he writes voluntarily acknowledged him to be such as he was. The ministers of Satan, it is true, had endeavored to trouble this Church also, but it is evident that their machinations were fruitless. He associates, however, two others along with himself, as being, in common with himself, the authors of the Epistle. Nothing farther is stated here that has not been explained elsewhere, excepting that he says, “the Church in God the Father, and in Christ;” by which terms (if I mistake not) he intimates, that there is truly among the Thessalonians a Church of God. This mark, therefore, is as it were an approval of a true and lawful Church. We may, however, at the same time infer from it, that a Church is to be sought for only where God presides, and where Christ reigns, and that, in short, there is no Church but what is founded upon God, is gathered under the auspices of Christ, and is united in his name.
