1 Thessalonians 1:1

Paul, and Silvanus, and Timotheus
These are the persons concerned in this epistle, and who send their greetings and salutations to this church; Paul was the inspired writer of it, and who is called by his bare name, without any additional epithet to it, as elsewhere in his other epistles; where he is either styled the servant, or apostle, or prisoner of Christ, but here only Paul: the reason for it is variously conjectured; either because he was well known by this church, having been lately with them; or lest these young converts should be offended and stumble at any pompous title, which they might imagine carried an appearance of arrogance and pride; or because there were as yet no false apostles among them, who had insinuated anything to the disadvantage of Paul, as in other places, which obliged him to assert his character and magnify his office; or rather because this was the first epistle he wrote, and he being conscious to himself of his own meanness, and that he was the least of the apostles, and unworthy to be called one, chose not to use the title. Silvanus is the same with Silas, who was with the apostle at Thessalonica and at Corinth, when he wrote this epistle; he was originally a member of the church at Jerusalem, and was one of the chief of the brethren there, and a prophet; see ( Acts 17:4 ) ( 18:5 ) ( Acts 15:22 Acts 15:23 ) , Timothy was also with the apostle at the same place, and was sent back by him from Athens to know their state, and returned to Corinth to him with Silas; he stands last, as being the younger, and perhaps was the apostle's amanuensis, and therefore in modesty writes his name last: the reason of their being mentioned was because, having been with the apostle at this place, they were well known by the church, who would be glad to hear of their welfare; as also to show their continued harmony and consent in the doctrines of the Gospel; they stand in the same order in ( 2 Corinthians 1:19 ) ,

unto the church of the Thessalonians:
which consisted of several of the inhabitants of Thessalonica, both Jews and Gentiles; (See Gill on Acts 17:4), who were called under the ministry of the word by the grace of God, out of darkness into marvellous light, and were separated from the rest of the world, and incorporated into a Gospel church state. This was a particular congregated church of Christ. Some have thought it was not as yet organized, or had proper officers in it; since no mention is made of pastors and deacons, but the contrary is evident from ( 1 Thessalonians 5:12 1 Thessalonians 5:13 ) , where they are exhorted to know, own, and acknowledge them that laboured among them, and were over them in the Lord, and esteem them highly for their works' sake. This church is said to be

in God the Father;
were interested in his love and free favour, as appears by their election of God, ( 1 Thessalonians 1:4 ) , and they were in the faith of God the Father, as the Father of our Lord Jesus Christ, and in the profession of it, and so were distinguished from an assembly of Heathens that were in the faith of idols, and not of the one true and living God, and especially as the Father of Christ; they were in fellowship with God the Father, and they were drawn by the efficacy of his grace to himself and to his Son, and were gathered together and embodied in a church state under his direction and influence; he was the author of them as a church, and they were plants of Christ's heavenly Father's planting, not to be plucked up; and they were, as the Arabic version renders it, "addicted" to God the Father; they were devoted to his service; they had his word among them, which they had received not as the word of men, but as the word of God; and his ordinances were duly and faithfully administered among them, and attended on by them:

and in the Lord Jesus Christ;
they were chosen in him before the foundation of the world; they were chosen in him as their head and representative; they were in him as members of his body, and as branches in the vine; they were openly in him by the effectual calling and conversion, were in the faith of him, and in the observance of his commands, and in communion with him; and so were distinguished from a Jewish synagogue or congregation: all this being true, at least of the far greater part of them, is said of them all, in a judgment of charity, they being under a profession of the Christian religion:

grace be unto you, and peace from God our Father, and the Lord Jesus
Christ.
This is the apostle's usual salutation and wish in all his epistles to the churches; (See Gill on Romans 1:7), the words "from God our Father and the Lord Jesus Christ" are left out in the Vulgate Latin and Syriac versions; and the Arabic version omits the last clause, "and the Lord Jesus Christ"; and the Ethiopic version only reads, "peace be unto you and his grace".
