The note of a true Church

1 Thessalonians 1:1

There were heathen assemblies in Thessalonica, numerous and powerful; but these were for the worship of false gods. The only true Church was this recent, despised, persecuted one, which rejoiced in the knowledge of the Creator of heaven and earth as their heavenly Father through Christ.

There was also a congregation of Jews. A synagogue stood there for the worship of the God of Abraham, Isaac, and Jacob, the only living and true God. But its people, by rejection of the Messiah and persecution of His saints, had transformed it into “a synagogue of Satan.”

But the Church, which Paul had planted, was “in the Lord Jesus Christ.” It was a Christian community. It was “in God the Father,” having been originated by Him, being His possession, receiving the tokens of His favour, and being governed by His laws. It was “in the Lord Jesus Christ,” its members having been gathered in His name, being knit together in His love, existing for His service, and preserved for His glory.
