One may say of the Thessalonian Jews that they not only were not born from the noble olive tree (see Rom 11:24), that ancient emblem of Judaism on coins.
They were also, in the Forerunner's phrase, a brood of vipers (see Lk 3:7; Mt 8:7).
According to Blessed Theophylact, "the apostles avoided dangers not from fear, but by God's prompting.
"For on this occasion, for example, they had already ceased preaching and no longer provoked the enemies.
"From Paul's withdrawal a twofold benefit came: the enemies' anger died down, and the preaching spread further.
"The inhabitants of Berea examined the Scriptures not as unbelievers, but as people unacquainted with the prophetic traditions.
"By examining the Scriptures and finding that the events concerning the Lord's Incarnation agreed with the words of the ancient prophets, they were thereby strengthened more firmly in faith."
"The Berean Jews proved considerably nobler than the Thessalonians. When they heard the preaching about the Messiah, they responded as sound reason required.
"They compared what they had heard with what was found in the books of Holy Scripture, bringing together the features of the Messiah proclaimed with those of the Messiah promised.
"They did this not only during the Sabbath assemblies, but every day.
"The natural outcome of this attentive testing of Paul's preaching was its zealous acceptance by the people.
"It was accepted not only by many Jews, but also by a considerable number of proselytes of both sexes.
"Among them were many people of rank, whose example had a beneficial effect on many.
"By happy exception, the Berean synagogue was peaceful. The apostle could live peacefully among the constantly growing Christian community.
"He even twice intended to go to Thessalonica, but, according to his words, he was hindered by Satan (see 1 Thess 2:18).
"This means either by illness from the angel of Satan (see 2 Cor 12:7), or by the unfavorable state of external circumstances.
"In these circumstances he discerned the influence of the evil spirit warring against Christ's Church (see Eph 6:11).
"Very soon the Thessalonian Jews sent emissaries here to raise a storm."
