Can We Meet to Worship Without a Sect?

Is it so that God’s children cannot meet to worship Him unless they meet in some sect name, some name other than the one Christ told us to meet in? Thank God, we find no difficulty in assembling together outside all sect names and enclosures. But sectarians are actually so blind that they think holy men cannot convene together to worship God and enjoy any means of grace unless they join some earthly craft; as though all grace were in the sect, and nothing in Christ.
