Bede the Venerable — as excerpted in the Catena Aurea on Luke 4:14-21

“And because wisdom belongs to teaching, but power to works, both are joined here, as it follows, And he taught in the synagogue. Synagogue, which is a Greek word, is rendered in Latin congregatio. By this name then the Jews were accustomed to call not only the gathering together of people, but also the house where they met together to hear the word of God; as we call by the name of Church, both the place and the company of the faithful. But there is this difference between the synagogue which is called congregation, and the Church which is interpreted convocation, that flocks and cattle, and any thing else can be gathered together in one, but only rational beings can be called together. Accordingly the Apostolical doctors thought right to call a people which was distinguished by the superior dignity of a new grace rather by the name of Church, than Synagogue. But rightly also was the fact of His being magnified by those present proved, by actual evidence of word and deed, as it follows, And he was magnified by all.”
