I know thy works. — Some would omit the word “works;” but the phrase “I know thy works” is admitted to be genuine in five out of the seven epistles; and it certainly seems natural to conclude that it was intended to be common to all, and to remind the Christian communities that whatever their state it was known to Him whose eyes were as a flame of fire. “We go from one hour to another, from one day and year to another, and what is once fairly past in our doing and omitting and suffering is scarcely regarded by us any more; it is like water that has flowed away. But into the omniscience of Christ all things are taken up” (Bengel).
Tribulation. — If persecution brought upon them poverty, it was the means also of unfolding to view their possession of the “true riches;” they were rich in honour, in that they were counted worthy to suffer; they would also grow rich in the graces which sufferings bring (Romans 5:3-5; James 1:2-4).
Blasphemy. — They had to endure reviling as well as tribulation and poverty; and, harder still, to hear some who blasphemed that worthy name by which they were called.
Jews. — The Jews were foremost in this. “It was in the synagogue that they heard words which reproached them as Nazarenes, Galileans, Christians, Disciples of the Crucified” (Plumptre). Comp. James 2:7. It is interesting to notice that this characteristic hostility of the Jews was illustrated in the martyrdom of Polycarp. The Jews, “as was their wont,” were foremost in bringing logs for the pile.
Synagogue of Satan. — The word “synagogue” is only once used to describe the Christian assembly (James 2:2); and even there it is called “your synagogue,” not the “synagogue of God.” In all other instances the “word is abandoned by the Jews.” With the “synagogue of Satan” here, compare “the throne of Satan” (Revelation 2:13), “the depths of Satan” (Revelation 2:24).
