As the manner of some is. — Some members of this community, it would seem, had persuaded themselves that the relation of Judaism to Christianity, of the “synagogue” (the Greek word here used seems to allude to this technical name, and yet intentionally to avoid it) and the Church, was such as to permit them to avoid close intercourse with Christians and direct association with Christian assemblies.
