Second, he depicts his own stay among them, sealed by a lofty moral character recognized by them themselves (2:1-16). Third, he depicts his fatherly and heartfelt cares for them (2:17-3:13).
Having received pleasant news about the Thessalonians from Saint Timothy, Saint Paul rejoiced over it (3:9). In his joy, he gives thanks to God for all the good with which He had been pleased to endow the Thessalonians.
From the first word he raises their mind to God. By pointing to Him as the accomplisher of their progress, he suggests that they belong to God and that the work of their faith is God's work.
Saint Paul begins almost all his Epistles with thanksgiving, and some with almost the same words (Rom 1:8-9; Eph 1:16; 2 Thess 1:3; 2 Tim 1:3). Yet this is not a mere turn of speech or a matter of custom.
It is the expression of real feelings with which his soul was filled; see 3:8-9. Called to the work of God, he could not fail to rejoice in its successes. Seeing God's finger tangibly in everything, he could not fail to thank God.
"We give thanks to God always," he says. This is no exaggeration. The Apostle lived in God, and prayerful turning to Him did not depart from his face. Such is the power of the apostolic spirit, the bearer of the Spirit of God.
Thanksgiving in words was not continuous, of course, but it was always present in the feeling of the heart, ready to pass into words. That he gives thanks for all seems to be stated deliberately.
Although the Apostle knew that not all were perfect, he does not narrow the breadth of his thanksgiving. Through this, he opens in advance the way for his word into the hearts even of the imperfect, when the time comes to touch their correction.
By the words "making mention of you" and the rest, he defines the act of thanksgiving when it is expressed in words during prayer. The Apostle speaks as if to say: in our prayers, remembering you, we pour out grateful feelings to God.
But what were prayers among the Apostles? They made up half of their apostolic labors. "We will give ourselves continually to prayer and to the ministry of the word," they said when deacons were chosen for the Church of Jerusalem (Acts 6:4).
Saint Chrysostom says: "Thanksgiving to God for the Thessalonians is testimony to their great progress. For the Apostle not only praises them, but also thanks God as the accomplisher of all their progress.
"Moreover, he teaches them humility, as if saying that all this is the work of God's power. Thus he speaks of thanksgiving because of their good deeds, and of remembrance of them in prayers because of his love for them."
In other Epistles, thanksgiving appears as an introductory discourse, after which follows an indication of other subjects. Here, however, thanksgiving is closely bound to what follows and forms the subject of the first chapter.
Saint Paul thanks God for the Thessalonians as he thinks of the perfection of their Christian character and of God's election of them. These motives, or subjects of thanksgiving, are also marked in the structure of the discourse by the words "remembering without ceasing" (v. 3) and "knowing" (v. 4).
